The relative air-moisture is an important factor in the industry and quality controlling domains. Therefore very high performance respective to measurement accuracy, long term stability and equipment are required from a temperature–moisture probe used in the industry. The accurate Hygrometer TH309 fulfil all the called requirements. It offers high measurement accuracy up to 1% of the relative moisture and a dew point determination down to – 40 °C. If wished special measurement device can be realised to best fit the requirements of the customer. Moreover different Hand probes of the series TH309 can be connected to the hygrometer without need of new calibrations.
