These thermomanometers are designed as panel mount models. They are fitted with 2 capillaries. The temperature is measured with sensor at the end of one capillary that shall be placed in a sheath located either on a pipe or on an appliance body. The other capillary is connected to a special check valve located either on a pipe or on an appliance body and used for pressure measurements. Both the values are indicated on separate scales integrated into one device. Models differ in their temperature and pressure range, shape, digit font, colors and capillary length.
