FM-801Indoor high-precision formaldehyde detector
1、 FM801 Multi mode Formaldehyde Detector Main Features:
1. Meet the latest national standard GB/T, the detection principle of photoelectric photometry (formaldehyde gas reacts with β - diketone, and the color change is caused by the derivative of ranitidine), with high accuracy.
2. Unique host+colorimetric sensor box design: The sensor box can be inserted into the host for use, or used separately as a diffusion sampler (after sampling is completed, it can be inserted into the host to obtain readings), flexible and convenient, and can perform multi-point detection simultaneously.
3. The sensor box is compact and exquisite, and can be reused dozens to hundreds of times.
4. The unique diffusion filter effectively reduces the impact of environmental factors such as temperature and humidity on detection, and is currently the most stable formaldehyde detector (formaldehyde detector) on the market.
5. Formaldehyde concentration units can be selected: μ g/m3 (mg/m3), ppb (ppm).
6. Multiple detection modes are available: direct measurement at a single point, simultaneous measurement at multiple points with a sampler, and continuous monitoring.
7. It can be connected to the portable (fixed) multi-functional environmental quality testing system of Graves, and utilize the functions of Graves specialized software (reading, on-site annotation, storage, organization, analysis, reporting) to achieve a complete indoor environmental quality testing solution.
