29 Calibration certificates temperature Calibration certificates temperature Data loggers The best method for calibrating a data logger with an internal sensor is provided by circulating air, as found in a temperature or climate cabinet. The spatial temperature distribution in the testing room must be determined based on extensive measurements. Several programmable CTS temperature cabinets (CTS T-40/25) are used in Testo’s temperature laboratory. Pt100 probes in combination with a testo 400 or testo 950 reference measuring instrument are used as a reference.

Select the suitable calibrationpoints for your instruments in the range from +50 to +500 °C. Contact surface temperature probes are calibrated using a certain method according to your choice on different surfaces (steel, copper, aluminium). The reference is created with a Prema 3040 precision thermometer combined with several reference thermocouples. DKD ISO
