Portable temperature calibrator - Quartz
Termékleírás
QUARTZ calibrator consists of a metal block measuring 35 mm indiameter and 135 mm in height, it doesn't use externalrefrigerating liquids and the metal block is heated and cooled byPeltier elements.
QUARTZ is equipped with a PID microprocessor controller with aresolution up to 0,01 °C, setting of the standard ofmeasurement in °C, °F and K, programming of ascent/descentramps and storage of the thermostats' operative temperature.
In the QUARTZ-2I version, the instrument is equipped with anacquisition card having two adjustable inputs able to read: Pt1003/4 wires & thermocouples: E, J, K, N, R, S with automaticcompensation of the cold junction.
The REF input is provided for the reference sample probe, thusobtaining a complete calibration system which can be certified byAccredia centres, in compliance with ISO 9000 regulations.
The EXT input is provided for probes that are being tested;hence, the instrument can display the temperature of the well, thetemperature of the sensor to be checked and the temperature of thereference sample probe, at the same time.
The QUARTZ is equipped with the RS232 serial interface tooperate in automatic mode connected to the PC by means of the AQ2spsoftware which enables to carry out probe calibrations, test ofthermostat and cyclical life tests; test results can be stored andprinted, so they are easily traceable in compliance with ISO 9000standards.
