Meter for PPM HTV Portable Formaldehyde Tester ( Item#: E1248 )

The meter for PPM HTV directly measures airborne formaldehyde concentrations as well as ambient temperature. It's widely used in the following application scenarios:  
●Building materials and indoor air quality detection.   
●Environment and Public Health inspection.  
●Estate and property management.  
●Industrial production process of formaldehyde detection, such as paint and paper manufacture.   
●Hospitals, pharmaceutical and clinic formaldehyde detection.   
●Tracing the formaldehyde release source in the environment.   
●To assess the efficiency of hvac system.   
●To assess the efficiency of formaldehyde scavenger.
  With further importance being put on air quality in public buildings, the workplace and in homes, the formaldehyde tester is aimed towards being the most accurate meter while still providing quick and simple operation  from a hand-held device.
