Therma-Hygrometer - hygrometer thermometer

- Thermometer, Hygrometer. - Max/min and alarm functions. - 0°C or less alert by audible alarm. - %RH and remote temperature probe. - Instruction manual - Certificate of conformity This therma-hygrometer simultaneously displays humidity and temperature in addition to indicating and recording maximum and minimum readings. Using the internal sensor, the instrument measures temperature over a range of 0 to 49.9°C. External remote probe with integrated three meter cable measures both temperature and humidity over a range of -49.9 to 69.9°C and 20 to 98% RH. The unit has a temperature alert alarm that sounds when the external remote sensor indicates the temperature is 0°C or below. This function is ideal for frost / frost alert in horticulture and the like. The therma-hygrometer is housed in an 18 x 41 x 76 mm ABS case, which incorporates a retractable stand. Each unit is supplied with a probe wall bracket.
