Resideo by Honeywell TD-090 Tridicator Pressure Temperature Gauge 75 PSI 1/4 NPT

The Resideo by Honeywell TD-090 Tridicator is a dual-function gauge designed to monitor both pressure and temperature in hydronic heating systems, boilers, and water heater applications. This compact gauge features a short probe design ideal for installations with limited clearance.

Key Features:

• Dual function design measures both system pressure and temperature simultaneously
• Pressure range: 0-75 PSI for accurate monitoring of residential and light commercial systems
• Temperature range: 60-320°F for comprehensive system monitoring
• Short probe configuration for tight installation spaces
• 1/4" NPT male threaded connection for standard gauge port installations
• Easy-to-read dial face with clear pressure and temperature markings
• Durable construction designed for long-term reliability in heating applications

The TD-090 tridicator provides essential system monitoring in a single gauge, eliminating the need for separate pressure and temperature instruments. The short probe design makes it particularly suitable for replacing factory-installed gauges on boilers, water heaters, and heating system expansion tanks where space is limited. The 1/4" NPT connection is the standard size for most residential and light commercial heating equipment.
