Digital Barometer is the perfect unit for plants, labs, and all other environments where there is a need to monitor conditions of environmental air parameters. A four-line LCD continuously and simultaneously shows barometric pressure, temperature, relative humidity, barometric pressure trend and time-of-day. Minimum\Maximum readings for barometric pressure, temperature and relative humidity are stored every hour for the last 24 hours and are available for recall at the touch of a button. HI/LO alarms can be set for barometric pressure, temperature, and relative humidity.
Barometric pressure range from 500 to 1030 millibars (mbar) with a resolution of 1 mbar. Accuracy is ±4 mbar. Barometric pressure trend shows in bar-chart format the current and past 1-, 3-, 6-, 12-, and 24-hour readings. Switching permits viewing in milibars (mbar), inches of mercury (inHg), or hectopascals (hPa). Altitude compensation is –100 to 2500 meters.
Temperature range is 32 to 131ºF and 0 to 55ºC. Resolution is 0.1° and accuracy is ±0.4°C. Relative humidity range is 5 to 95%. Resolution is 1% RH and accuracy is ±3% RH between 5 to 75%, otherwise ±5% RH.
Computer output allows unit to be connected to a computer using the accessory Computer Data Acquisition System to permanently capture readings
