The temperature and humidity probes used in industrial applications have to fulfil very high requirements in regards to measuring accuracy, long term and mechanical stability.
The B+B humidity probes of the series TH109 and TH209 have been developed to comply with these requirements. Whether with plastic or stainless steel housing, with voltage or current analogue output, they can be used in almost all industry and building control engineering applications. The measurement of the relative humidity is performed with capacitive sensor element of the newest generation.
