AZ Instrument Kooldioxidemeter VZ7752 - CO2, Temperatuur, Luchtvochtigheid

The AZ Instrument VZ7752 is a professional-grade carbon dioxide meter designed for accurate and reliable measurement of CO2 concentration, temperature, and relative humidity. Featuring advanced NDIR sensor technology, this device is ideal for indoor air quality monitoring in offices, schools, greenhouses, and industrial environments. With a large backlit LCD display, data logging capability, and adjustable CO2 alarm, the VZ7752 provides comprehensive environmental analysis.

Advantages

High-precision NDIR CO2 sensor ensures stable and accurate readings over a wide range. The device supports both manual calibration and automatic baseline correction (ABC) for long-term reliability. Data logging of up to 32,000 points allows for trend analysis via USB connection to a PC. The audible alarm with adjustable threshold alerts users to unsafe CO2 levels, enhancing safety.
