Hygrometers - The 6100 & 6102 therma-hygrometers are easy to use hygrometers, or relative humidity and air temperature measuring meters. The units measure %rh over the range of 0 to 100%rh with a resolution of 0.1 %rh and temperature over the range of -20 to 70°C with a resolution of 0.1°C/°F. 
 
These humidity meters incorporate a clear custom LCD with °C, %rh, max/min, hold and dew point indication. There is an automatic display of both open circuit and low battery. These units display humidity and temperature simultaneously and additionally incorporate a backlit display. 
 
The units are powered by three 1.5 volt AAA batteries with a minimum life expectancy of up to 10000 hours. An auto power off facility turns the therma-hygrometer off automatically after 10 minutes, maximising battery life. 
 
The 6100 / 6102  therma-hygrometers utilise an interchangeable probe that incorporates a one-metre lead with a 6-pin Lumberg connector. If the probe needs to be replaced, the instrument will not require recalibration as the probes are fully interchangeable. 
 
ATTENTION HUMIDITY SENSOR The Humidity Sensors housed in these products are susceptible to contamination from pollutants such as solvents and exposure to saturated air and therefore are not covered under the 2 year warranty. Furthermore it is expected that the sensor's readings will drift by up to 0.5% per year.
