Factory second Air Quality Monitor - from 0.01 mg/m³ TVOC / HCHO

Take control of your indoor air quality with the SBS-DT-74 from Steinberg Systems. This compact device monitors both formaldehyde (HCHO) and volatile organic compounds (TVOC) – two of the most common indoor pollutants – and displays the readings side by side in real time. Highly sensitive sensors detect concentrations from just 0.01 mg/m³ and provide continuous updates on air conditions. With practical features like max, min and hold modes, plus easy switching between ppm and mg/m³, you can monitor the air in homes, offices, workshops or public buildings with complete confidence.

Designed for portability and ease of use, this air quality monitor runs on three AAA batteries (not included) and features a clear LCD screen with optional backlighting for any lighting conditions. It powers down automatically to conserve battery life and is housed in a durable ABS and polycarbonate casing. Whether you're carrying out professional assessments or simply want peace of mind at home, it gives you the insight you need to reduce pollutants and improve indoor air quality.
