240-1500 Portable Dry block calibrator


  • Product info

EJB 240-1500 temperature calibrator is a compact instrument used to calibrate transducers, 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.

  • Stability : ±0,03°C (at 0 °C) ± 0.05°F (at 32 °F)
  • Display resolution : 0,1°C / 0,01°F (all temperatures)
  • Display accuracy : ±0,15°C (± 0.27°F)
  • Units of measurement : °C - °F - K
  • Serial interface : RS232
  • Well diameter : 35 mm (1.3 in.)
  • Insert hole depth : 130 mm (5.1 in.)
  • Power supply : 115 or 230 VAC - 50/60 Hz

- Axial : ±0,1°C (for 60 mm from the bottom) / ±0.1°F (for 2.3 in. from the bottom)
- Maximum heating time: 20°C/min (68 °F/min)
- Maximum cooling time: 22°C/min (71.6 °F/min)

EJB 240-1500 calibrator consists of a metal block measuring 35 mm in diameter and 135 mm in height, it doesn’t use external refrigerating liquids and the metal block is heated and cooled by Peltier elements.
EJB 240-1500 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 the EJB 240-1501 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 temperature of the well, the temperature of the sensor to be checked and the temperature of the reference sample probe, at the same time.

The EJB 240-1500  is equipped with the RS232 serial interface to operate in automatic mode connected to the PC by means of the 241-300 software which enables to carry out probe calibrations, test of thermostat and cyclical life tests; test results can be stored and printed, so they are easily traceable in compliance with ISO 9000 standards.
