Thermocouples (TCs) are widely used type of temperature sensors which made by two different metals
and used for industrial temperature measurement from low temperature to ultrahigh
temperature.
Kowa provide variety range of thermocouples to meet each requirements such as explosion
proof type thermocouples for explosion hazardous site as well as general industrial use
thermocouples.

Platinum Resistance Temperature Detectors (PRTs) are widely used temperature sensors almost made
by platinum that exploit the predicable change in electrical resistance of materials with changing
temperature and used for high-accuracy temperature measurement from extremely low temperature to
high temperature.
Kowa provide variety range of PRTs to meet each requirements such as explosion proof type PRTs
for explosion hazardous site as well as general industrial use PRTs.
