P755

Application profile

The universally applicable process-controlled hand-held 
instruments, Series P700, 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

Product features

- USB interface 
- Optional DE-Graph Windows Software for graphic and 
tabular documentation
- High measuring accuracy
- Integrated calibration function for simple compensation 
of sensor tolerances
- Physical 1-point, 2-point or 3-point calibration function
- Measuring channels are freely assignable
- Recording maximum, minimum, hold and average values
- Integrated sensor holder for one hand operation
- Mains operation possible
- Simultaneous display of two measured values
- Differential temperature display

P650

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.
