the HCHO (formaldehyde) sensor’s crosssensitivity to a single gas of certain concentration. Mixtures of gases were not tested, and results with mixed gases are unpredictable. Crosssensitivities to all the compounds are only valid for a specified concentration and may be different for higher concentrations of the same compound.

PCEVOC 1 is a portable handheld volatile organic compound (VOC) and formaldehyde (HCHO) meter or gas leak detector for indoor air quality (IAQ) monitoring applications. This easytouse VOC meter is ideal for measuring total volatile organic compound (TVOC) and formaldehyde (HCHO) levels in homes, offices, factories, laboratories, hotels, schools and other indoor environments.
VOC gas sensor is second generation solution. it can detect HCHO roughly, because this sensor only expresses the whole concentration of VOC gas, not just HCHO only. DFRobot Gravity Formaldehyde sensor module can detect and measure HCHO gas concentration accurately.
SGP40 is Sensirion’s new digital VOC (volatile organic compounds) sensor designed for easy integration into air treatment devices and air quality monitors. Based on Sensirion’s CMOSens ® Technology , the SGP40 offers a complete sensor system on a single chip and features a digital I 2 C interface, a temperaturecontrolled microhotplate and a humiditycompensated indoor air quality signal.
The BAPI VOC sensor provides a CO2 equivalent ppm output so that Ashrae’s popular CO2based VRP procedure can be used for DCV; however, CO2 is not one of the VOCs that the sensor monitors. If your application needs to directly measure CO2, choose a CO2 sensor. Commissioning and Testing. BAPI’s VOC sensor is easily tested for proper operation.
Formaldehyde (/ f ə r ˈ m æ l d ə h aɪ d / fərMALdəhide, also / f ɔːr ˈ/ for) (systematic name methanal) is a naturally occurring organic compound with the formula CH 2 O (H−CHO). The pure compound is a pungentsmelling colorless gas that polymerises spontaneously into paraformaldehyde (refer to section Forms below), hence it is stored as an aqueous solution (formalin).

4/1/2016· 2. Humidity is a problem. Humidity is a huge problem with some PIDs. Most PIDs and their users are blind to RH effects: Water vapour scatters and absorbs photons, reducing the PID output. This is also called ‘quenching.’. With high RH, you may find current leakage along the sensor walls, resulting in higher than actual readings.
