ASL F100 digital thermometer: High performance handheld 2-channel hand held thermometer for Pt100 & Thermistor probes. UKAS/ISO certification available.
The Lufft C101 Reference digital thermometer is 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 and 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 P600 series digital thermometers have a special calibration function which compensates 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 and 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 & RS232 interface. The instrument processor corrects the tolerance of the measuring probe defined by the number code & corrects the peobe deviation error. The corrected measured value is displayed in the LCD.

These measuring instruments can be calibrated to un coded measuring probes through a further instrument function 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 sensor.

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 and the values entered into the instrument through the keyboard. The instruments monitor the calibration process automatically so that the operation is automatically broken off in the case of references which are unstable for example, in order to be able to continue to use the previously correction values in the processor.

To achieve good results only high performance temperature references standards should be used for calibration such as a metal block bath or liquid calibration bath with good temperature uniformity.

DE-Graph software is available for the P600 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 entering 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 the same as the accuracy of the measuring instrument itself.

The resulting high system measuring accuracy predestines the measuring instruments for applications in quality assurance & in-house calibration laboratories

Need a fully automated temperature calibration system ? the Dostmann P600 series have been included in the equipment list which "Caliso Temps" software supports.

The new Dostmann P700 series 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.
