Overview

The Uni-T UT337A is a professional-grade, portable carbon monoxide (CO) meter designed for technicians who require immediate and reliable gas detection in the field. This compact device utilizes a high-precision electrochemical gas sensor to detect CO concentrations ranging from 0 to 1000ppm, ensuring that even trace amounts of this hazardous gas are identified quickly.

Built with the HVAC professional in mind, the UT337A features a dual-display LCD that simultaneously shows the current CO concentration and the maximum recorded level. This allows for real-time monitoring while tracking peak exposure levels during a site inspection. With its short response time and user-configurable alarms, it serves as a critical safety companion for any indoor environment where gas appliances are present.

Why It Matters

Carbon monoxide is a colorless, odorless gas that can be fatal if undetected. The UT337A provides a first line of defense, offering an adjustable zero-point for temperature compensation and a self-calibrated sensor. This ensures that your readings remain accurate across varying environmental conditions, protecting both the technician and the client from potential CO poisoning during appliance servicing or routine maintenance.
