HMS P-Series (Low Heat-Shock)
HMS P-Series (Low Heat-Shock)
The HMS P-Series is a special design for low heat-shock behaviour. It is a single element thermopile sensors in small TO-46 package and are optimized for temperature measurements (e.g in-ear thermometers). Due to the stable measurements even in heat-shock situations the measurement speed can be increased without loosing accuracy. Like all our sensors, the HMS sensors support a fully modular concept. You can choose a thermopile sensor chip size and an infrared filter which is mounted from the outside to improve the measurement accuracy. Additionally, the sensor can be equipped with an optional thermistor providing temperature reference.
Features and Benefits
- Special low heat-shock design
