The British Made low cost 6500 therma-hygrometer measures both relative humidity and air temperature. The instrument displays %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.

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.


General DescriptionThe 6500 therma-hygrometer incorporates a clear custom LCD with °C, %rh, max/min, hold and dew point indication. An auto power-off facility turns the instrument off after 10 minutes’ non-use.
