Product Description

The HAL-CO**1, based on reliable electrochemical sensing technology, features directly displays the carbon dioxide concentration in ppm, and is easy to use. A short, low-resistance diffusion pathway with a built-in pump enables a rapid reaction time.Low power design allows long operation time. Exceptional stability allows very long intervals between calibration checks. The external digital temperature and humidity sensor or pressure sensor allows compensation or correction for accurate measurement. The USB port provides capability of downloading stored data and continuous, real-time monitoring of the environment.
