Lufft C101 hand held Reference digital thermometer. Unique in its class with an accuracy of 0,02°C in the range from -40...200°C. This is achieved by means of high-quality, coiled, glass-sealed PT100 sensors & precision electronics with a 24 bit analogue/digital converter. Both the sensor & the electronics are pre-aged in an intricate process & in this way achieve excellent long-term stability. DKD certification available.

To minimise measurement uncertainty of the complete system (instrument and sensor) the P700 series accurate hand held digital thermometers have a special calibration function which compensates for the sensor tolerances when a sensor/probe is replaced. Probes are tolerance calibrated in the Dostmann laboratory. The calculated deviation is converted into a unique hexa decimal code which is marked on the probe handle.

This two line hex code contains information of the probe deviation at zero point & span in relation to the respective DIN standard on which it is based. The number code is simply entered & stored in the measuring instrument using either the front keypad or via software & USB interface. The instrument processor corrects the tolerance of the measuring probe defined by the number code & corrects the probe deviation error. The corrected measured value is displayed on the LCD display.

These Dostmann thermometers can be calibrated to un coded measuring probes by simple physical compensation (comparison measurement). At the same time this function can be used to easily correct any possible drift error caused by ageing of the probes internal detector.

For physical calibration you can select either a 1, 2, or 3-point temperature calibration. To implement this function the measuring probes to be calibrated are immersed, for example, in two reference temperature points (optional 1 or 3 points) one after the other & the values entered into the instrument through the keypad. The instruments monitor the calibration process automatically so that the operation is automatically broken off when references are unstable for example, in order to be able to continue to use the previously correction values in the processor.

DE-Graph software is available for the P700 series measuring instruments & permits simple, efficient administration of the various measuring sensors & the transfer for readout of the appropriate code on the measuring instrument. The software can be used to lock the keyboard preventing operators entry to the calibration function area, a practical function to prevent inquisitive fingers! As a result, the above-described calibration function eliminates the influence of the probes sensor error to a greater extent & gives a system accuracy which is about equal to the accuracy of the measuring instrument itself.

The resulting high system measurement accuracy predestines these instruments for applications in product quality assurance & in-house calibration laboratories

Need a fully automated temperature calibration system ? the Dostmann P700 series have been included in the equipment list which "Caliso Temps" automatic temperature calibration software supports.

The Dostmann P795 digital thermometer offers 4 calibration functions in addition to the DIN EN 60751 :

Calibration by sensor code/ oP1, calibration by physical standard references / oP2, calibration according to Coefficients of EN60751 (R0,ABC) / oP3, and Smart EE prom-probes with internal calibration (AUTO-Detection)/ oP4.
