recording ambient conditions in the lab, monitoring differences that could
affect sample analysis, and predicting weather changes.
unit simultaneously displays current barometric pressure, bar graph of
barometric trends, humidity, temperature, and date or time. Switches permit
setting in °F or °C, and in.Hg or mbar.
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 Tehcnology.
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. There is an adjustable altitude compensation 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).
Units display relative humidity with a resolution of 1%. Accuracy is ±5 RH.
Temperature range is from 23 to 131°F and 5 to 55°C. Accuracy is ±1°C.
Surprisingly 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.
