## Description Barometer measures pressure in three different units. Fisher Scientific™ Traceable™ Hygrometer/Thermometer/Barometer/Dew Point Pen has a user selectable dual display which shows humidity/temperature, humidity/dew point, barometer/temperature or barometer/humidity. Displays several units of measure: inches of mercury (inHg) from 0.29 to 32.48 with a resolution of 0.01, millibars (hPa) from 10.0 to 1100 with a resolution of 0.1 and 1hPa, and millimeters of mercury (mmHg) from 7.5 to 825.0 with a resolution of 0.1mmHg. - Lightweight; Compact design features an electronic capacitance - Tough ABS plastic housing (1.50 x 8 x 1.50 in.) - Water-resistant; O-ring sealing; High contrast 0.375 in. high LCD digits - Membrane keypads provide longer durability - HOLD button freezes the reading on the display - At the press of a button, unit recalls minimum/maximum readings #### Certifications Individually serial-numbered Traceable Certificate is provided from an ISO 17025 calibration laboratory accredited by A2LA™. It indicates traceability to standards provided by NIST™. **Includes**: Traceable certificate, four AAA batteries ## Specifications ||| | ------------ | ------------ | |Accuracy|±1°C| |Dimensions (L x W)|8 x 1.5 in.
