How to find the ASL products under WIKA?
New product designations for the ASL product portfolio
The company ASL, a leading manufacturer of AC resistance bridges and high-accuracy hand-held thermometers, has been part of the WIKA Group since January 2013.
With this acquisition the product range in the field of calibration technology with the measurement parameter temperature offered by WIKA has been extended.
In order to integrate the products into the WIKA websites, the previous model designations have been changed. Regarding their technical features the products remain unchanged.
What do different abbreviations like RTD, PRT, SPRT… mean?
RTD (Resistance Temperature Detector) – a temperature sensor whose resistance changes with temperature
PRT (Platinum Resistance Thermometer) – RTD using platinum wire for the resistance element
Pt1000 – PRT with 1,000 Ohm at 0 °C.
Pt500 – PRT with 500 Ohm at 0 °C.
Pt100 – PRT with 100 Ohm at 0 °C.
Pt25 – PRT with 25 Ohm at 0 °C.
Pt10 – PRT with 10 Ohm at 0 °C.
SPRT (Standard PRT) - high-stability PRT designed for use as a reference thermometer
What is a SMART probe?
The "SMART probe" is a precision RTD sensor with an electronic memory in its coupler connector. This memory chip stores the coefficients of the calibrated sensor and a complete history of the probe. This history includes the maximum and minimum value that the sensor has been exposed to and also the calibration dates.
