Volatile organic compounds and formaldehyde meter

The DT-900A meter is a universal instrument for testing the concentration of formaldehyde HCHO and volatile organic compounds (VOCs) in indoor air. Due to the prevalence of air pollution by formaldehyde and VOCs and their proven harmfulness, the issue of measuring the concentrations of these substances is becoming increasingly important. The small size, weight and advanced measuring systems of the DT-900A meter provide convenience of use and high mobility of the instrument. Measurements, ranges: - HCHO formaldehyde concentration: 0.0 ~ 5.00 mg/m³ (or ppm) - resolution: 0.01mg/m³ (or ppm) - accuracy: ±5%. - VOC concentration: 0.0 ~ 9.99 mg/m³ (or ppm) - resolution: 0.01mg/m³ (or ppm) - accuracy: ±5% Functions, features: - LCD display - Auto Power Off - working temperature 0°C ~ 40°C - alarm level indicator - low battery voltage indicator - power supply: lithium polymer battery 1200mAh/7.4V - dimensions: 165x60x25 mm - weight: 584 g Included: - lithium polymer battery - 9V 1A power adapter - manual
