Technoline WL1025 CO2-monitor met temperatuur en luchtvochtigheid

Equipped with an NDIR sensor, the WL1025 measures CO2 from 400 to 5000 ppm with an accuracy of ±50 ppm + 5% in the 400–2000 ppm range. It also tracks temperature (0–50 °C) and relative humidity (20–95 % RH).

Overview

The Technoline WL1025 is a compact indoor air quality monitor. A traffic light indicator gives an immediate visual cue: green for good, yellow for elevated, red for high CO2 levels. An audible alarm can be set to warn when CO2 exceeds a user-defined threshold. The backlit LCD shows current CO2, temperature, and humidity, along with maximum and minimum values.
