| Housed in a waterproof metal box with glass door, the electronic converter is composed by two parts: - the microprocessor based electronic circuit, that supplies digital O2 reading; 4-20 mA output, alarms, etc. - the power group with regulation of the power of the electric heater. The high brightness led display continuously exhibits the measured oxygen (as ppm if the oxygen content is < 0,2% or as percentage if > 0,2%). By pressing a button, the temperature of the probe and the impedance of the cell can be read on the display. The analyser must be completed with reference and calibration pneumatic box Mod. 60 or 62 (see specific catalogue).
