EJB 8721 DEW POINT-THERMA-HYGROMETER The Therma-Hygrometer is an easy to use relative humidity, air temperature and dew point measuring instrument. The display incorporates a custom LCD display with ‘°C/°F’, ‘% RH’, Dew Point, ‘Max/Min’ and ‘Hold’ indication. There is an automatic display of both ‘Open Circuit’ and ‘Low Battery’. Display : 12 mm LCD Temperature range : 0 to +90°C resolution 0,1°C Temperature sensor : semi conductor Accuracy temperature : ± 0,5°C ± 1 digit Humidity range : 10 — 95 % RH resolution 0,1 % Humidity sensor : thin film polymer Accuracy humidity : ± 3 % ± 1 digit Dew point Battery : 9V PP3 / MN1604 Battery life : 100 hours Dimensions : 36 x 80 x 147 mm Weight : 210 g Generale info The Therma-Hygrometer simultaneously displays the % RH, temperature and dew point. The unit measures % RH over the range of 0 to 100% RH with a resolution of 0.1% RH and temperature over the range of 0 to +90°C with a resolution of 0.1°C or °F switchable. An auto power off facility turns the Therma-Hygrometer off automatically after 20 minutes which maximises battery life. The unit is powered by a 9 volt alkaline PP3 battery with a minimum life expectancy of up to 100 hours or via a 9/230 volt AC/DC power adaptor for continuous use. The Therma-Hygrometer probe is detachable via a 6-pin connector, however if the probe requires replacement, the instrument will require recalibration. Supplied complete with carrying case, battery and instructions for use. RH calibration test capsules are available for 33% and 75% RH (supplied as a pair).
