Application profile
The multi-function-instruments are outstanding for their 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.

P700 / T900 series - Calibration function
Accurate measurements at any time
through integrated calibration function
To minimise measurement uncertainty of the complete system
(instrument and sensor) the P700 series and T900 series measuring instruments have a special calibration function which compensates the sensor tolerances when a sensor is replaced.
To this end all our measuring sensors are tolerance calibrated
in our laboratory. The determined deviation is converted into a
number code which is marked on the sensor.

This code contains information on the sensor deviationn at zero

Application profile
An instrument which meets the highest demands. The 2-channel-resistance thermometer automatically detects our Pt100smartprobes with integrated EEprom. Thereby the calibration
characteristic of each probe is transferred automatically to the
uracy
instrument. The thermometer will achieve a system accuracy

of ± 0,015K (instrument + probe). Both measuring channels
