Temperature Products GmbH

P655

Application profile  The universally applicable process-controlled hand-held instruments, Series P600, are ideal for measuring operations in which high accuracy counts or the possibility of online documentation is demanded.

Areas of application in industry and laboratory for example  
- For taking measurements for quality assurance under ISO 9000
- As a reference instrument for checking production
- For taking comparison measurements in service and repair
- For registration of humidity and temperature in air conditioning and environmental engineering
- Long-period monitoring of temperature and/or relative humidity with online documentation

P655 The two multi-function-instruments are outstanding for theri high accuracy of ±0,03°C.
You can optional plug in Pt100 or thermocouple (type J, K, L, N, R, S, T), as well as probes for humidity and flow. The high precision makes them eminently suitable as reference instruments for testing subordinate measuring instruments in quality assurance laboratories or for checking temperature-critical processes.
These instruments are frequently provided with a DKD calibration certificate.
