Wika 51090A006G4 Bimetal Dial Thermometer 0-250F 9in Stem

Product Description

The WIKA 51090A006G4 is a bimetal dial thermometer designed for temperature measurement in industrial and mechanical systems. It features a 9-inch stem length with bottom-connected mounting, making it suitable for insertion into pipes, tanks, ducts, and process equipment. The thermometer reads from 0 to 250 degrees F (-20 to 120 degrees C) and carries a 1.0 percent accuracy rating. The housing and stem are constructed from stainless steel (18-8 grade), providing corrosion resistance in wet or chemical-exposed environments. HVAC technicians, plumbers, and industrial service technicians install this instrument to monitor fluid or air temperatures in a wide range of applications.

This thermometer is well suited for residential and light commercial HVAC systems, hydronic heating and cooling circuits, domestic hot water systems, boiler supply and return lines, and general process piping where a direct-reading dial instrument is preferred over electronic sensors. The bottom-connected mount allows vertical installation into tees, wells, or tank walls. The 9-inch stem provides adequate immersion depth for accurate readings in larger pipe diameters or insulated piping systems.

Key Features

• Temperature range: 0 to 250 degrees F (−20 to 120 degrees C)
• 1.0 percent accuracy rating for reliable process monitoring
• 9-inch stem length for adequate immersion depth
• Bottom-connected mount for vertical or inline installation
• Stainless steel housing and 18-8 grade stem for corrosion resistance

Compatibility

Designed as a direct-reading bimetal thermometer for use in HVAC, plumbing, and light industrial piping systems where a bottom-connected, 9-inch stem dial thermometer is required.

Installation Notes

Installation is typically performed by a licensed HVAC technician or plumber. Shut off and depressurize the system before installing or removing the thermometer from any pipe or tank fitting. Use an appropriate thermowell or tee fitting to ensure a proper seal and to allow future removal without system shutdown. Follow all applicable local mechanical codes when installing temperature instruments in pressurized systems.
