Frequently Asked Questions

What is Traceable?

In the context of measurement science, traceability is the property of a measurement result in which the result can be related to a national measurement reference through a documented unbroken chain of calibrations. National measurement standards are maintained by national measurement institutions (NMIs) such as the National Institute of Standards and Technology (NIST) in the United States. The ISO/IEC 17025 accredited calibration certificate that comes standard with our Traceable® Products is recognized in all European countries. With every, Traceable® Product, you receive the product, detailed operating instructions, individual serial number, Traceable® calibration label, and a Traceable® Certificate. The certificate displays detailed information for your specific serially-numbered product, indicating its traceability to NIST. The Traceable® calibration label provides the original calibration date and the calibration due date; it is a constant reminder of the next required re-certification date.

Who requires it?

Everyone who is, or wants to be ISO-certified.

  • Military suppliers
  • Government labs, from FDA to USDA
  • Labs maintaining certification programs
  • Labs requiring the utmost in accuracy
  • Hospital and clinical labs fulfilling CLIA requirements
  • Labs desiring to use the best possible practices for all measurements
What are ISO/IEC 17025 traceability requirements?

ISO/IEC 17025:2017 mandates traceability in clause 5.6.1, which states in part:

"All equipment used for tests and/or calibration, including equipment for subsidiary measurements (e.g. for environmental conditions) having a significant effect on the accuracy or validity of the result of the test, calibration or sampling shall be calibrated before being put into service. The laboratory shall have an established program and procedure for the calibration of its equipment."

Calibration Service
What is the Calibration Service?

For those customers who need to show continued compliance with a quality system, Traceable Products provides a re-certification service to recalibrate all Traceable® products. Most users re-certify their equipment on an annual basis. Some with special requirements do it more frequently.

Simply send it to Traceable Products. No return authorization number is required. Upon receipt, Traceable Products will contact you with re-certification costs and await instructions.

What is "As Found" data and "As Left" data?

When recalibrating your measurement device, you have the option to receive “As Found” data, “As Left” data, or both.

As Found calibration data is calibration data acquired before any repairs or adjustments being made to the device. In other words, it is the condition of the device “as found” when arriving at our facility for calibration. This provides the user an opportunity to ensure that the instrument was reading accurately, and within specification, while it was in use. It offers valuable information and documentation to support an end user's test results. It also provides record-keeping on the instrument's long-term linearity and stability.

As Left calibration data is calibration data acquired after any repairs or adjustments are made to the device, i.e., the condition the device was left before shipping back to you. The condition of the device used to acquire the as left data will be the same condition in which you will receive your device.

If I replace the battery on my instrument, will it need re-calibration?

None of the Traceable® products will need re-calibration or re-certification due to a battery change.

What is the cost of recalibration?

Each device will be estimated per as found or as left data.

Returned shipping cost - $20. Please include a working battery and probe in package being shipped to Traceable Products.

*cost may vary by product condition, Cal points, and any additional customizations

Product Support
What is MIN/MAX and can I set it?

These are measurement readings recorded to represent the minimum (lowest or min) value achieved and the maximum (highest or max) value achieved since the instruments. If the memory is cleared, it will display the most recent reading. These are temperature values that cannot programmable.

What are Hi/Lo Alarms and how do I set it?

If your instrument comes with this feature, you can set the alarm values. The instrument will alarm when readings are above or below the set values. Setting the values will be dependent on the product. See the manual on each product page or contact us at 281.482.1714 or email us.

What is IN/OUT?

The IN is the ambient temperature around the thermometer's environment, and the OUT is the measurement of the bottle probe. This does not reflect if the instrument is in or out of its environment.

What does accuracy mean?

Accuracy is the parameter which characterizes a measurement instrument’s ability to measure with the range of the true theoretical value of the measured quantity.

What does resolution mean?

The instrument will display beyond a whole number. These are referenced as significant digits.

What are the bottle/vaccine bottles filled with?

Bottle probes are filled with non-toxic glycol solution, which GRAS (generally recognizes as safe) by the US FDA.

Why is my product screen blank, faint, or giving erratic readings?

Check the battery; it may need replacing. If you are still receiving errors after battery replacement, remove the batteries. Press all the buttons-one at a time. Put the batteries back in. If issues still occur, please contact customer service at 281.482.1714 or email us.

Why does my product screen display LLLL?

If the temperature of your environment is within the thermometers' or hygrometers' measuring range, this error will occur if the probe is disconnected or damaged.

Why does my product screen display HHHH?

If the temperature of your environment is within the thermometers' or hygrometers' measuring above the range, this error will occur if the probe is disconnected or damaged.

Why are my two instruments displaying different temperatures?

When comparing two thermometers, you must add the tolerances of the two units together to identify the total amount of variance that may occur between the two units and still be considered within specification. For example, when comparing two devices of the same model that has a +/- 1˚C accuracy, the two units can display temperatures that are up to 2˚C different. When comparing temperatures of different model thermometers, it is important that the probe types of both devices are equivalent.

This device provides recorded data in a CSV format that can be transferred from the thermometer to any computer with the use of a USB flash drive. No specific software is needed for the device and data can be deleted from memory. The device has a memory capacity of up to one year when using one-minute intervals.


This datalogger device provides recorded data in a CSV format that can be transferred from the thermometer to any computer with use of a USB flash drive. The data on each unit cannot be overwritten or modified, thus reliably securing information that should not be deleted.

Datalogger (DDL)

Traceable® device that logs and records data over a period about its environment or application. Monitor readings overnight, on weekends, or for any time with rolling data log. The user-defined datalogging interval of one observation/minute to one observation/24 hour. Memory capacity maintains a year of recorded data when using 1-minute intervals and longer when using larger intervals.

Traceable® Certificate

Multi-point calibration on an individually-numbered Traceable® Certificate which assures accuracy from our ISO/IEC 17025:2017 (1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognized national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement.

Smart Alarm™

When an out-of-range condition is sensed, the Smart-Alarm™ triggers. Smart-Alarm™ features visual and audible indicators which signal continuously until acknowledged, even if the parameter returns to the non-alarm range.

Hi/Lo Alarms and Time/Date Stamp

Alarm tracking feature stores in memory each alarm event detailing when the alarm state occurred, as well as when the unit returned back to within range. Alarm state indicators include visual LEDs, audio alerts, and flashing LCD segments. Data for up to 10 different alarm events can be retrieved with the most current event viewable on display.

Bottle Probe

Bottle probes are sealed in a miniature bottle filled with nontoxic glycol. A solution is GRAS (generally recognized as safe) by the FDA (Food and Drug Administration). Eliminates concerns about incidental contact with food or drinking water. Temperature-buffered bottle sensor eliminates rapid changes when a refrigerator door is opened. Ideal for use in monitoring storage conditions for vaccines or other important samples.
