Abstract

The invention relates to the technical field of electrolytic tank temperature control, in particular to a Karl Fischer moisture meter electrolytic tank simple heating device which comprises a main frame body arranged on the outer side of an electrolytic tank in a sleeving mode, and an inner side installation clamping groove is formed in the included angle position of the inner bottom face of the main frame body. The simple heating device for the electrolytic tank of the Karl-Fischer moisture meter can be used for heating the electrolytic tank of the Karl-Fischer moisture meter, monitoring the temperature of the electrolytic tank in real time and maintaining the stable temperature of the electrolytic tank, and effectively solves the problems of instability, poor precision, short service life and the like when a Karl-Fischer reagent is used for detecting the moisture of lubricating oil at a relatively low temperature; heat generated by the heating device can be directly conducted to the electrolytic tank, the temperature rise is rapid, the temperature control is accurate, and overheating is avoided; the heating device can shield an induced electromagnetic field generated when the flexible heating film is electrified and heated through the copper foil, operation of the Karl Fischer moisture meter is not interfered, and stability and precision of the meter are not affected.
