PST offers a wide range of gas, oxygen, and level sensors as well as measurement instruments including probes, transmitters, analyzers and real-time online monitoring systems. Our products and solutions measure relative humidity, moisture, dew point, water activity, temperature, CO2, differential pressure, pressure, oxygen and trace impurities.


Our measuring instruments and monitoring solutions are easy to use, need little maintenance and conform to GAMP and FDA requirements. The portfolio – known particularly for temperature measurement and monitoring of relative humidity – includes industrial probes, humidity sensors, measurement probes and data loggers, handheld instruments, transmitters and OEM products. Apart from humidity and temperature measurement, it is designed for monitoring of CO2, differential and process pressure, flow, dew point, water activity and analog signals.

Our Real-time Monitoring System (RMS) monitors various measured data – simply and reliably.

Services such as mapping, validation and calibration round off our portfolio.
