Bimetal Thermomanometer Eco WIKA Model THM10


The model THM thermomanomeer combines the measurement of pressure and temperature in one instrument. This enables the control of both measurement parameters at one single measurement point. The built-in measuring elements-Borudon tube and bimetal coil-provide for reliable measuring result.

By using the self-sealing shut-off valve, the measuring instrument can be dismounted at any time and without having to empty the heating circuit first. The bimetal thermomanometer is delivered with a shut-off valves as standard.
