Wika 52872802 Bimetal Dial Thermometer 0-250F 6in Stem

Product Description

The WIKA 52872802 is a bimetal dial thermometer designed for temperature measurement in HVAC, plumbing, and industrial process applications. It reads from 0 to 250 degrees F (negative 20 to 120 degrees C) and features a 6-inch stem for insertion into pipes, ducts, or wells. The back-connected mount positions the dial face forward for easy reading when the thermometer is installed inline or through a wall fitting. Accuracy is rated at plus or minus 1.0 percent of full scale. The housing and stem are constructed from 18-8 stainless steel, making it suitable for environments where corrosion resistance is required. Licensed HVAC technicians and plumbers are the primary installers.

This thermometer is used in residential and light commercial HVAC systems, hydronic heating and cooling loops, domestic plumbing lines, and refrigeration monitoring applications. The 6-inch stem length accommodates standard pipe diameters and thermowell installations. The back connection orientation suits panel-mount or direct-pipe installations where the dial needs to face outward from a surface. It is a direct-read instrument requiring no power source or wiring.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation thermometer for back-connected bimetal dial thermometer applications in residential and commercial HVAC, plumbing, and hydronic systems.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Before installing, isolate and depressurize the pipe or system section and allow it to cool to a safe handling temperature. Use a thermowell where required by system design to allow removal without draining the line. Verify the stem insertion depth does not contact the opposite pipe wall, and torque fittings to the fitting manufacturer's specification using appropriate thread sealant compatible with the process fluid.
