Electronic digital barometers measure atmospheric pressure, graphically display the barometric trend, and report relative humidity and temperature. Ideal for recording ambient changes in the lab, monitoring conditions affecting sample analysis, and assisting in the prediction of weather changes.
Traceable to NIST for accuracy
To assure accuracy an individually serial-numbered Traceable® Certificate is provided from our ISO 17025 calibration laboratory accredited by A2LA. It indicates traceability to standards provided by NIST (National Institute of Standards and Technology).
Memory stores barometric readings
Graphic barometric trend shows present reading and previous 1-, 3-, 6-, 12-, and 24-hour readings in a bar chart format. Hourly digital barometric readings are stored in memory and can be recalled and displayed for each of the past 24 hours. Adjustable altitude compensation is from –100 to 2500 meters. Barometer measures pressure from 23.45 to 31.01 inches of mercury (inHg) with a resolution of 0.03 inHg and from 794 to 1050 millibars (mbar) with a resolution of 1 mbar. Accuracy is ±0.1477 inHg (±5 mbar).
Weather forecasting
Units display relative humidity with a resolution of 1% RH. Accuracy is ±5% RH. Temperature range is 32 to 131°F and 0 to 55°C. Accuracy is ±1°C. Exceptionally accurate forecasting indicators show weather conditions for the next 24-hours using symbols for sunny, cloudy, rainy, and partly cloudy. Temperature and humidity are updated every 9 seconds, barometric pressure every 15 minutes. Switches permit setting in Fahrenheit/Celsius and inHg/mbars. Units are supplied with stand, wall-mount, and batteries. Replacement battery Cat. No. 1105.
