The total error of measurement results from the sum of the measuring error of device and probe. In order to minimise these, we offer you the following each other calibrated and optimized measuring systems. This due to theirExcellent system accuracy is excellently suited to quality assurance within the framework of ISO 9000 ff, as a reference devices in manufacture, service and maintenance, etc. The system optimisation is done by sensor alignmentWith the help of zero point and slope. Due to the low test current there is no self-heating of the sensor is also compensated thermal voltage is measured.This text is machine translated.
