Carbon monoxide meter VZ7701 AZI-VZ7701

The portable VZ 7701 meter is designed to detect carbon monoxide in the air. The construction of the meter is based on modern microprocessor technology. A new generation electrochemical sensor is used for the measurement, which is characterized by a fast-quick-changing response and high accuracy. The CO concentration is measured in the range of 0 - 999 PPM (millionths). Indications are displayed on a two-field LCD panel with a resolution of 1PPM. The device has an acoustic signaling of exceeding the set thresholds. The user can select the alarm threshold after exceeding which the acoustic signaling will be activated, from the following values: i.e. 25 (factory setting), 30, 35, 40, 50, 70, 100 or 200PPM. After exceeding the alarm threshold, in the range up to 200 PPM, the current CO
