Dwyer Instruments TRI-200-50 Tridicator Gauge 0-200 PSI 1/2" NPT Center Back Mount

The Dwyer Instruments TRI-200-50 is a Series TRI Tridicator Gauge that combines a pressure gage and thermometer into a single, easy-to-read instrument. Designed for boiler monitoring and hydronic heating systems, this tridicator eliminates the need to install two separate instruments, saving both installation time and cost.

Featuring a movable dual-scale dial with blue pressure markings and red temperature markings, the TRI-200-50 displays pressure in both psi and kPa (0–200 psi / 0–1400 kPa) and temperature in both Fahrenheit and Celsius (80–290°F / 30–140°C). The 1/2" NPT center back mount (CBM) connection makes it well-suited for direct panel or pipe installation.

Key Features:

• Dual-function instrument: measures both pressure and temperature simultaneously
• Pressure range: 0–200 psi (0–1400 kPa)
• Temperature range: 80–290°F (30–140°C)
• Connection: 1/2" NPT center back mount (CBM)
• Movable dial with color-coded scales — blue for pressure, red for temperature
• Pressure accuracy: ±3-2-3%; Temperature accuracy: ±1 scale division
• Brass connection with phosphor bronze Bourdon tube for durability
• Drawn steel case with black finish
• Ambient operating range: -40 to 250°F (-40 to 120°C)
• Media compatibility: water, oils, inert gases, and compatible liquids

The Dwyer Series TRI Tridicator is an ideal solution for heating and cooling system monitoring where both pressure and temperature readings are required at a single measurement point.
