UYIGAO Brand New Handheld Portable Meter for PPM HTV Digital Formaldehyde Tester Methanal Concentration Monitor Detector with LCD Display Sound and Light Alarm

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.

Features:
Portable detector for detecting formaldehyde concentration in both parts per million (ppm) and mg/m3.
Can continuously monitor the HCHO gas concentration in the surrounding environment.
Sound and light alarm works when HCHO gas concentration reaches the level of the alarm.
Compact size, light weight, easy to carry and operate.
Professional and accurate measurement with audible / visual alarms.
Internal vibrating alarm for high noise environments. 
Large LCD display and ℃/℉ switch.
Can set automatic shutdown time and concentration of alarm value.
