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.

An optional 3-point (25, 50 & 75%rh) UKAS Humidity Calibration Certificate is available at a preferential price when purchased with these therma-hygrometers. Select this option from drop-down.

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.
