The portable Uni-T UT337A carbon monoxide detector enables reliable measurement of CO concentration in the range of 0–1000 ppm with a fast response of < 60 s. Thanks to the electrochemical sensor, simultaneous display of the current and maximum value, and adjustable audible and visual alarms, it is ideal for quick safety checks of the environment and basic indoor air quality monitoring.
The Uni-T UT337A CO meter is designed for a quick real-time overview of carbon monoxide concentration. It uses an electrochemical CO sensor with self-check and the option of user calibration, which helps maintain accurate results during long-term use. The instrument displays both the current and the maximum measured value at the same time, making it easy to detect short-term peaks.
For convenient field use, it features a backlit LCD display and a Data Hold function to “freeze” the reading. Temperature compensation for zero setting and selection of °C/°F units are also included. A low-battery indicator and automatic power-off to save energy are practical additions.
Main benefits and features:
