Wal-Rich 1722002 – 1/2″ NPT Hot Water Thermometer with Steel Case and Brass Well

The Wal-Rich 1722002 is a hot water thermometer engineered for monitoring system temperatures in hydronic and plumbing applications. Designed with a 1/2″ NPT connection and a 6-inch steel case, it delivers reliable readings across a wide temperature range. This model is commonly installed in boiler piping, domestic hot water lines, and other pressurized systems where temperature verification is required.

Application

This thermometer provides direct temperature monitoring with an analog dial calibrated from 40°F to 280°F. It includes a brass thermowell for thermal conductivity and protection, allowing safe removal or replacement without draining the system. Its compact design supports use in both vertical and horizontal piping configurations.

Key Features
