Temperature range: 70 - 320°F, 20 - 160°C Pressure: 0 - 75 PSI Dimensions: 1 1/2 inches (1.59-inch) insertion depth; 2 1/2-inch dial; 1/4-inch NPT pipe thread installation Merges three vital boiler safety metrics—operating pressure, medium temperature, and water level—into a single unit. It replaces the conventional trio of pressure gauge, thermometer, and level indicator, slashing installation connection points and mitigating the risks of steam or hot water leakage effectively. Boasts a 2.5-inch dial with dual calibrated scales (0–75 PSI for pressure; 70–320°F for temperature). Color-coded visual cues allow for instant, intuitive readings, enabling operators to spot parameter anomalies at a glance. Broad Application Scope A go-to monitoring solution for boilers, hydronic heating systems, hot water tanks, plumbing lines, as well as a full spectrum of commercial and residential heating equipment.
