Universal Enterprises t220/3 Pocket Dial Thermometer

Product Description

The UNIVERSAL ENTERPRISES t220/3 is a pocket dial thermometer calibrated in Fahrenheit, designed for field temperature measurement in HVAC, plumbing, and refrigeration service. Compact enough to carry in a shirt pocket, it gives technicians a fast, tool-free way to check air temperatures, fluid temperatures, and surface readings at the job site. The dial face provides direct Fahrenheit readout with no batteries or calibration setup required, making it a reliable go-to instrument for everyday field checks.

This thermometer is suited for residential and light commercial service work. HVAC technicians use it to verify supply and return air temperatures, check refrigerant line conditions indirectly, or confirm water heater output. Plumbers and service techs reach for pocket dial thermometers when a quick, non-electronic temperature check is needed during inspections or commissioning work.

Key Features

• Fahrenheit-only dial face for direct field readout
• Pocket-sized form factor for easy carry and access on the job site
• No batteries required — purely mechanical dial operation
• Suitable for air, fluid, and general-purpose temperature measurement

Compatibility

Designed as a general-purpose pocket dial thermometer suitable for HVAC, plumbing, and refrigeration field service applications.

Installation Notes

Insert the probe stem fully into the medium being measured and allow sufficient stabilization time before reading the dial. Handle the dial face and stem carefully to avoid bending, which can affect calibration accuracy. No power source or tool is required for operation, but the instrument should be periodically verified against a known reference standard per your quality assurance procedures.
