Milwaukee 2225-20 Voltage Detector Infrared Thermometer

Product Description

The MILWAUKEE ELECTRIC TOOL CORP 2225-20 is a combination non-contact voltage detector and laser infrared thermometer built for residential and commercial HVAC service work. The voltage detector senses AC voltage from 12 to 1000 volts and carries a CAT IV 1000V safety rating, the highest category for electrical safety standards. The infrared thermometer covers a temperature detection range of -22 to 482 degrees F, giving technicians a wide measurement window across all common HVAC operating conditions. An LCD backlit display delivers clear, readable output in low-light environments. Both detection functions are integrated into a single handheld tool, reducing what a technician needs to carry on a service call.

This tool is designed for HVAC technicians performing residential and commercial service calls where both electrical and temperature diagnostics are required. Typical applications include verifying live voltage at disconnect boxes, contactors, and control boards, as well as measuring supply and return air temperatures, refrigerant line surface temperatures, and equipment surface readings. The wide temperature range accommodates everything from sub-freezing refrigeration systems to high-temperature heat exchanger surfaces. The CAT IV voltage rating makes it suitable for use at the service entrance level, not just downstream branch circuits.

Key Features

• Non-contact AC voltage detection from 12 to 1000 volts with visual and audible indicators
• CAT IV 1000V safety rating for use in high-energy electrical environments
• Laser infrared thermometer with detection range of -22 to 482 degrees F
• LCD backlit display for clear readings in low-light or confined service areas
• Dual-function design combines voltage detection and temperature measurement in one tool

Compatibility

Designed as a general-purpose diagnostic instrument for residential and commercial HVAC service applications requiring non-contact voltage detection and infrared temperature measurement.

Installation Notes

This instrument is intended for use by qualified HVAC technicians and licensed electricians familiar with electrical safety procedures. Always confirm voltage detection results with a calibrated meter before performing any wiring work. De-energize and lock out equipment per NFPA 70E procedures before servicing electrical components. The non-contact detector confirms presence of voltage only and is not a substitute for a full multimeter measurement.
