UNI-T UT337A Carbon Monoxide Meter Details

Suitable for use everywhere from in the house to restaurants, offices and industrial areas, the UT337A measures the exact value of carbon monoxide (CO) present in the air.

Featuring a built-in sensor integrated into the top of the unit, the UT337A measures CO content from 0-1000ppm with accuracy of ±5% (5ppm) and resolution of 1ppm. The sensor is also designed to adjust rapidly to changes, ensuring you always get a stable, accurate reading.

When CO levels exceed a certain threshold, the UT337A will alert the user by using a combination of audible and LED light indicators. The alarm is configurable to the user's specification and it is also possible to use this meter to calculate temperature values.

Great tester

Review by Handyman (Posted on 04/10/2018)


Needed a CO tester after a trigger on the generic alarm at home. The UNI-T was the cheapest(!) available and gave the peace of mind that the trigger was probably false. I now offer screening tests when visiting customers.
