DT-900A/900C Formaldehyde/TVOC Rapid Screening Instrument (DT-900C)

Sensor: Imported high-quality fuel cell sensor Formaldehyde range [or PPM]: 0.00~5.00 mg/m3(or PPM) Formaldehyde-Resolution [or PPM]: 0.01 mg/m3(or PPM)

The DT-900A/900C can quickly measure formaldehyde and TVOC values in real time, meeting the air pollution testing needs of different occasions and reflecting the degree of air pollution in real time. It is suitable for quickly locating formaldehyde and TVOC pollution sources in homes, offices, factories, hotels, schools and other indoor environments, and can quickly detect formaldehyde and TVOC concentration values in the air and calculate the air pollution index.

Mass Weighing Range-PM2.5: 0~2000 μg/m³ Mass Weighing Range-PM10: 0~2000 μg/m³ Air Temperature Measurement-Temperature Measurement Range: -20至70°C

The DT-968/969 meter is a compact, simple, and efficient air quality meter from CEM that integrates PM2.5, PM10, formaldehyde (only applicable to DT-969), temperature and humidity measurement into one unit.

Detected Gas: Combustible gas, carbon monoxide, oxygen, ammonia, sulfur dioxide, hydrogen sulfide, carbon dioxide, methane, nitrogen oxides, benzene, nitrogen, VOC, TVOC, chlorine, and other gases in any combination Response Time [T90]: ≤20 seconds (T90) Detection Accuracy [Depends on specific sensor]: ≤±3 % (depends on specific sensor)

The multi-in-one gas detector is a fixed detection device capable of real-time, continuous monitoring of multiple gas concentrations in the environment.

GS302M-SD adopts the NDIR infrared absorption detection principle, combining an advanced optical path, precision circuits, and intelligent software to form a general-purpose infrared CO2 sensor module. GS302M-SD uses a single light source and a dual-channel detector to achieve spatially dual-optical-path reference compensation. The microprocessor performs signal acquisition, processing, and output, achieving ambient temperature compensation, correcting the nonlinear relationship inherent in the principle, and offering multiple output forms. It features the good selectivity unique to NDIR products, high sensitivity, no oxygen dependence, and long service life.
