240-0350 Calibrateur de température portative


  • Info produit

EJB 240-0350 temperature calibrator is a compact instrument used to calibrate trans­ ducers, RTD and temperature-measuring sensors in the field and in the laboratory. The possibility to generate positive and negative temperature ramps makes it suitable for use in calibrating and testing thermostats.

Insert with customiozable holes.

Info
EJB 240-0350 temperature calibrator consists of a metal block measuring 50 mm in diameter heated by a resistance which winds around the outer surface of the block.
A hole having diameter 35 x 190 mm is made in the block for the appropriate reduction inserts.

EJB 240-0350 is equipped with a PID microprocessor controller with a resolution up to 0,01°C, setting of the standard of measurement in °C, °F and K programming of ascent/descent ramps and storage of the thermostats’ operative temperature.

In EJB 240-0351 version the instrument is equipped with an acquisition card having two adjustable inputs able to read: Pt100 3/4 wires & thermocouples: E, J, K, N, R, S with automatic compensation of the cold junction.

The REF input is provided for the reference sample probe, thus obtaining a complete calibration system which can be certified by Accredia centres, in compliance with ISO 9000 regulations.

The EXT input is provided for probes that are being tested; hence, the instrument can display the temperatures of the furnaces, the temperature of the sensor to be checked and of the reference sample probe, at the same time.

Furthermore, EJB 240-0350 is equipped with the RS232 serial interface; it can operate in automatic mode connected to the PC by means of the 241-300 software which enables to carry out probe calibrations and cyclical life tests; test results can be stored and printed, so they are easily traceable in compliance with ISO 9000 standards.
