Wika 52877123 Bimetal Dial Thermometer 0-250F 2.5in Stem

Product Description

The WIKA 52877123 is a bimetal dial thermometer designed for temperature measurement in HVAC, plumbing, and industrial process applications. It reads from 0 to 250 degrees F (-20 to 120 degrees C) and uses a back-connected mount for direct inline or pipe-tee installation. The stem measures 2.5 inches in length and is constructed from 18-8 stainless steel, making it resistant to corrosion in wet or chemically active environments. The housing is also stainless steel. With a 1.0 percent accuracy rating, this thermometer provides reliable readings for commissioning, troubleshooting, and routine system monitoring. HVAC technicians, plumbers, and mechanical contractors are the typical installers.

This thermometer fits residential and light commercial applications where a compact, durable temperature gauge is needed. Common install locations include hydronic heating systems, domestic hot water lines, chilled water circuits, and boiler supply or return piping. The 0 to 250 degrees F range covers most hot water heating and cooling system operating temperatures. The back-connected configuration suits installations where the gauge face needs to read flush against a panel, wall bracket, or pipe assembly without an angled stem.

Installation Notes

A licensed plumber or HVAC technician should install this thermometer into a properly sized thermowell or threaded pipe fitting. Shut off and depressurize the system before threading the stem into the well or fitting. Do not overtighten the stem connection; use appropriate thread sealant per local plumbing code. Verify the stem is fully immersed in the process fluid to ensure accurate readings.
