Meter VZ77597 AZI-VZ-77597

Professional multifunctional air‑analysis meter

This advanced meter, equipped with high‑class sensors, is an indispensable tool for professionals and anyone concerned with air quality in their environment. The device enables simultaneous measurement of carbon monoxide (CO), carbon dioxide (CO2), humidity, ambient temperature, dew‑point temperature (DEW POINT) and wet‑bulb temperature (WET BULB). Its versatility makes it suitable for many sectors – from the food industry, through agriculture, to HVAC system monitoring.

Precision and functionality for demanding applications

The meter uses a stable and accurate NDIR sensor for CO2 measurement and a high‑quality electrochemical sensor for CO. In addition, a precise Rotronic sensor provides reliable humidity readings. Results are clearly displayed on a large back‑lit LCD screen. Functions such as HOLD, MIN/MAX, TWA and STEL allow detailed data analysis. An integrated data logger (DATALOGGER) can store up to 32 000 measurements with date and time, facilitating documentation and trend analysis. USB connectivity enables easy data transfer to a PC.

Wide range of applications and benefits

The device is ideal for monitoring air quality in:

• Workstations – ensuring safe working conditions.

• Agro‑food industry – controlling food storage conditions.

• Poultry farms and greenhouses – optimizing growth conditions for plants and livestock.

• Food warehouses and CO2 cylinder storage – maintaining proper storage environments.

• Rooms with CO2‑based fire‑extinguishing systems – checking gas concentration after discharge.

• Breweries, carbonated‑drink bottling lines and distilleries – monitoring fermentation processes.

• Fermentation industry plants – controlling production processes.

• Verification of HVAC (air‑conditioning and ventilation) installation correctness.

Additional features:

• Auto‑calibration: Automatic calibration of CO/CO2 sensors ensures long‑term measurement accuracy.

• Alarm signaling: Audible alarm warns when set threshold levels are exceeded.

• Power supply: Battery or mains operation provides usage flexibility.

• Energy saving: Automatic shutdown after 20 minutes of inactivity extends battery life (deactivatable feature).

• Dew‑point (DEW POINT) and wet‑bulb (WET BULB) temperatures: Enable precise assessment of humidity conditions.

The meter complies with CE marking, confirming its conformity with European safety and quality standards. The package includes alkaline batteries and a transport case for convenient storage and carrying.
