COMMETER Thermometer Hygrometer Barometer

COMMETER Thermometer Hygrometer Barometer Thermometers, hygrometers, barometers are designed for measurement of temperature, relative humidity, dew-point, atmospheric pressure and atmospheric pressure tendency. Advantages: * included traceable calibration certificate * dual line LCD display with special symbols * dew-point reading * barometric pressure tendency reading for last three hours * adjustable dual alarm with audio indication for each channel * memory of minimum and maximum values * function Hold - manual storing of actual values for later displaying COMMON TECHNICAL PARAMETERS Operating temperature range: -10 to + 60° C Temperature sensor: RTD Ni1000/ 6180ppm Accuracy of temperature measurement with built-in sensor: ± 0.4° C Accuracy of temperature input without probes - C3631 instrument: ± 0.2° C from -50 to + 100° C, ± 0.2% from reading from 100 to 250° C Accuracy of air humidity measurement: ± 2.5% RH from 5 to 95% at 23° C, resolution 0.1% Accuracy of dew point reading: ± 0.5° C from 30 to 95% RH Accuracy of air-pressure measurement: ± 2hPa at 23° C, resolution 0.1hPa Barometric pressure tendency reading: in hPa - for last three hours Power: battery 9V Battery life: 4 months typically ( barometer 2 months typically) Warranty: two years
