Electrochemical Type Gas Sensors

NAP-505

NAP-505 gas sensor is our standard type of electrochemical CO gas sensor for a CO detector for domestic use. Detection principle is quite the same as conventional one, but quite cheaper than conventional ones due to unique structure and renovated electrodes. NAP-505 has already been approved by UL. (UL2034 – Residential CO detectors)

NE-HCHO

NE4-HCHO is a formaldehyde gas sensor, and is applicable for detecting and measuring formaldehyde generated from woody construction material or remained concentration after sterilization.Since it can detect even 0.5ppm of HCHO, it is applicable for various equipment. By adhering to industry standards for size and connection orientation, the NE4-HCHO can be retrofitted easily to existing product designs.

NE-NH3

NE4-NH3 is very stable in normal circumstance for more than 6 months, and can detect ammonia with excellent accuracy without reduction of sensitivity. Additionally, since it is applicable in exceedingly low temperature, it is available for many applications. By adhering to industry standards for size and connection orientation, the NE4-NH3 can be retrofitted easily to existing product designs.
