Our Calibrations

Askey's Calibration. Dept.

In order to keep your registration meters in perfect condition you can have them checked and calibrated. If you want this to be done on a yearly basis you could take a subscription to have your meters annually calibrated and adjusted, if necessary. Of course you can send in your data loggers at any time without the need of an agreement, but an annual checkup gives you more certainty. In addition, when you have a calibration agreement you keep the costs down. Below you will find an overview of the possibilities that we offer.

During the calibration of a temperature sensor three fixed points are checked. In advance you can indicate which points you prefer. You can choose from the temperatures in the table below, but also other temperatures or more than 3 measuring points are possible against additional costs. The fixed points (deg. Celsius) that can be used are as follows:

Standard -38 -20 0 20 40 60 80
High -38 -20 0 20 40 60 80 100 120 140
Low -80 -60 -40 -38 -20 0 20 40 60 80

During calibration and adjustment of a humidity sensor two fixed points are checked, t.w. 33% and 76% relative humidity.

CO2 calibration consists of two fixed points: 0 ppm and 1.600 ppm.

Contains calibration of a thermocouple or analog recorder/adapter.
