The converter mod. H705 is a panel transmitter that can convert the electric signals coming both from zirconia cell and from the compensation thermocouple type B built in FER high temperature oxygen probes mod. 4153.

Microprocessor based, connected to an analogue to digital 16 bit converter, it is equipped with a high brightness led display (3½ digit) that continuously visualize the oxygen measurement and the temperature measured by the compensation thermocouple, the resistance of the cell at high temperature (in order to evaluate the electrode level of use) and all settable parameters by pressing some keys. The junction box is equipped with a connector to make cabling easy
