Threshold Formaldehyde HCHO Sensor offers an easy-to-use solution to monitor HCHO levels. This device features a wide voltage range (5-24V) & has both high & low-level signals. Plus, it has an indicator light to quickly check the status. If the gas concentration exceeds the set threshold, the device will output a high-level signal & the light will be on. When the gas concentration falls beneath the threshold, the sensor emits a low-level signal & the light will switch off.
Formaldehyde, with the chemical formula CH2O or HCHO, is a colorless gas with a strong, pungent odor. It is soluble in alcohols and ethers. Acute formaldehyde poisoning is a systemic disease primarily characterized by damage to the eyes and respiratory system, caused by exposure to high concentrations of formaldehyde vapor. When the concentration reaches 0.08-0.09mg/m3 in ambient air, children may experience mild wheezing. At 0.1mg/m3, there may be odor and discomfort. At 0.5mg/m3, it can cause eye irritation and tear production. At 0.6mg/m3, it can cause discomfort or pain in the throat. Higher concentrations may result in nausea, vomiting, coughing, chest tightness, asthma, and even pulmonary edema. A concentration of 30mg/m3 can be fatal.
Note: The threshold of this sensor is factory-fixed and cannot be modified by the user. Custom threshold parameters can be set for bulk orders.
If you need to measure formaldehyde concentration accurately, we recommend the MEMS Formaldehyde HCHO Gas Detection Sensor.
