Multifunctional air parameters meter AZ 77535

AZ 77535 meter is a professional, portable device that allows you to quickly and easily monitor indoor air quality. It allows the simultaneous measurement of carbon dioxide, temperature and humidity.

It has a built-in NDIR sensor that allows for precise measurement of CO2 levels in real time and a high-class Rotronic sensor for measuring humidity. The results are presented on a three-field LCD display. User can set the CO2 alarm threshold after exceeding which the sound signaling will be activated, change the temperature reading units (°C or °F) and select the values ​​displayed on the LCD panel.

Device can work in the mode of measuring current values, minimum / maximum values ​​(MIN and MAX functions) and average values ​​for 8 h and 15 min time intervals (TWA and STEL functions). HOLD button makes it possible to stop the indications with a quick response.

Observation, archiving and printing of the measured parameters can be done via a PC after prior software installation (not included).

AZ 77535 has the function of automatic calibration of the CO2 sensor and a two-point calibration of the humidity sensor. The backlit LCD panel makes it easy to read the indications in low light conditions, e.g. at night or in poorly lit rooms.

Meter can be powered by 4 x 1.5V alkaline batteries or via a DC 9V 1A power adapter. In addition, it has an automatic power cut-off function after 20 minutes. idle and low battery indication.

APPLICATION
Measurements at workplaces, agri-food industry, poultry farms, greenhouses, food warehouses, CO2 cylinder warehouses, extinguishing agent warehouses, rooms with a CO2-based fire extinguishing system, breweries, carbonated drink bottling plants, distilleries, fermentation industry plants, for monitoring industrial processes, verification of the correctness of HVAC installations (air conditioning and ventilation)
