Thermographs

Thermographs a temperature measuring device that works by virtue of mechanical change principle. It consists of two metal bands. The coefficient of thermal expansion is not equal. Bring it together. When heated, both metals exhibited unequal expansion. Metal band deflection In general, thermometers are designed to measure both temperature and humidity

Thermograph can record data with the Revolving Cylinder, which can record up to 30 days without needing batteries. It is suitable for temperature measurement in areas riskt sparks
