Liquid expansion thermometers for temperatures from -60ºC to 650ºC for aluminum models and from -60ºC to 200ºC to polyamide ones.
These instruments are very tough, easy to install and reliable.

Useful for controlling the fluid temperature in tanks or pipes of boat motors, engine cooling systems, boilers, Industrial Refrigeration and Air Conditioning installations, etc.

Requests for Naval catalogue references can be made:

ISSA code
IMPA code

For temperatures up to 200°C polyamid cases are available, its low thermal conductivity prevents energy losses and frost formation when working at low temperatures.

In case of breakage or damage, all its components (glass rod, thermowell or case), are replaceable by new parts. This parts are also interchangeable with spare parts of other manufacturesrs as long as they comply with DIN standards. See:

DIN 16195 establishes the accuracy of these instruments.

Gesa has ENAC traceable devices that guarantee th accuracy during the manufacturing stages and of certificates issued.
All thermometers can be certified if requested.
