Basic components of the probe include a platinum cathode 7 and a silver
anode 8. The cathode 7 bears a Teflon film 10 secured by nylon threads 9. The
membrane and the rubber bushing make the membrane assembly 11 put onto the
bushing and filled with electrolyte 13. The temperature sensor is nested in the
casing 14. The protective bushing 15 covers the probe electrode member and is
thread-joined with the cable sleeve 16.
The cable 17 connects the probe electrode member to the convertor unit.
