Uni-T UT337A Carbon Monoxide Tester

The Uni-T UT337A Carbon Monoxide Tester is a portable handheld device designed for detecting carbon monoxide (CO) concentrations in the range of 0–1000 ppm. It features an electrochemical sensor with a response time of less than 60 seconds for 90% of the reading, ensuring real-time monitoring of CO levels.

• Accurate detection: ±5% or 5 ppm accuracy with 1 ppm resolution
• Audible and visual alarm: adjustable threshold alerts you when CO levels exceed safe limits
• Data Hold & Max Hold: freeze readings or track peak concentration
• Backlit LCD display: clear readings even in low light
• Auto power-off & low battery indicator: extends battery life and prevents unexpected shutdown

Powered by 4 AAA batteries (included), the UT337A is ideal for home, workplace, or industrial safety checks. CE and RoHS certified.
