  • Info produit

EJB 240-202-FT is a portable thermostatic liquid calibrator used for checking thermocouples and platinum resistance thermometers in the laboratory as well as in the field.

EJB 240-202-FT is possible to calibrate temperature sensors with the same accuracy and precision of a thermostatic bath.

EJB 240-x00-FTx models are suitable both for low and high temperature ranges. In addition, they are available with a double built-in temperature indicator in order to compare the reference probe with the external probe. 240-202-FT can be used with different kind of accessories: dry blocks, dry bodies, extension tubes, liquids and so forth.

  • Operating range : +20°C....+200°C
  • Display accuracy : ±0,15°C
  • Display resolution : 0,1°C  (all temperatures)
  • Stability : ±0,02°C at 150°C
  • Units of measure : °C - °F - K
  • Average heating time (stabilization included) : 10°C/min
  • Average cooling time (stabilization included) : 4°C/min
  • Axial uniformity : ±0,05°C at 0°C (for 60 mm from the bottom)
  • Radial uniformity (at 40 mm) : ±0,05°C (at 50 mm)
  • Switch test : yes
  • Calibrator size : 160 x 340 x 330 mm
  • Calibrator weight : 8 kg
  • Hole depth : 170 mm
  • Hole diameter : 60 mm
  • Power supply : 115 or 230 VAC - 50/60 Hz
  • Electric power : 500 W

All instruments are supplied with final testing, stability and accuracy certification traceable to EU standards

EJB 241-0100 (Size 59,5 x 170mm). Holes and diameters :
  • 2 x 4 mm
  • 1 x 4,5 mm
  • 1 x 5,5 mm
  • 1 x 6,5 mm
  • 1 x 8,5 mm
  • 1 x 10,5 mm
  • 1 x 12,5 mm
Every hole has a 160 mm (6,2in.) depth

In  EJB 240-202-FT the internal tank is heated with two electrical resistances and cooled by a fan.
EJB 240-202-FT is equipped with a new 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.

The mixing process ensures a proper heat transmission, excellent stability and uniformity values; the large size of the well makes it possible to test sensors of various lengths and diameters.

In the EJB 240-200-FTH version, the instrument is equipped with an acquisition card having two adjustable inputs (Pt100 3/4 wires, thermocouples: E, J, K, N, R, S) with bushes fitted with gold-plated contacts and 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.

Furthermore, EJB 240-200-FT 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, thermostats tests, and cyclical life tests; test results can be stored and printed, so they are easily traceable in compliance with ISO 9000 standards.

It consists of an aluminium vessel whose capacity is about 400 cc and it is constantly kept homogenous by a magnetic mixer whose speed is adjustable according to the viscosity of the fluid used.

The mixing process ensures a proper heat transmission, excellent stability and uniformity values; the large size of the well makes it possible to test sensors of various lengths and diameters.

Both low and high temperature EJB 240-x00-FTx are available in two different models. All these models can be accessorized with a double thermocuoples and a RTD (Resistance Temperature Detector) reader.
