The UNI-T UT337A is a professional-grade, handheld Carbon Monoxide (CO) meter designed to detect the presence of the "silent killer" gas with speed and precision. Carbon Monoxide is colorless, odorless, and tasteless, making a reliable digital detector an essential safety tool for HVAC technicians, home inspectors, and industrial safety officers. Whether you are checking for leaks in gas furnaces, water heaters, or testing indoor air quality in warehouses, the UT337A provides the real-time data needed to protect lives.
Designed with a user-friendly interface, the UT337A requires no complex setup. Once powered on, the sensor initializes and begins continuous monitoring. The device is programmed with standard safety thresholds, providing a "Caution" alert at 35 ppm and a critical "Warning" alert at 200 ppm. Its compact, lightweight design allows for comfortable single-handed operation, while the included wrist strap and rugged housing ensure it can withstand the demands of field work.
Reliability is a core feature of the UT337A. It utilizes an advanced electrochemical sensor, known for its long life and stability. The device also features an auto-power-off function to preserve battery life and a "Data Hold" button to freeze readings for easy logging. For professionals who need a dependable, easy-to-carry CO detection solution, the UNI-T UT337A is the definitive choice for maintaining a safe and breathable environment.
Key Features:
Dual Alert System: Features both an audible buzzer and a visual LED indicator that trigger at 35 ppm (Warning) and 200 ppm (Danger) to ensure immediate awareness of hazardous levels.
Smart Self-Calibration: Built-in self-calibration function ensures the sensor maintains accuracy over time and stabilizes quickly upon startup.
Ambient Temperature Display: Simultaneously monitors and displays the current room temperature in either Celsius (°C) or Fahrenheit (°F).
Maximum Value Hold: Includes a "Max" function that tracks and displays the highest CO concentration recorded during the session, ideal for identifying peak leak periods.
Backlit LCD for Low Light: Features a clear, backlit digital display for easy reading in dark mechanical rooms, basements, or industrial environments.
