NAP-520 Electrochemical Hydrogen Sulphide Gas Sensor

The NAP-520 is an electrochemical gas sensor with 3 electrodes for the detection of Hydrogen Sulphide (H₂S) in a variety of gas detection applications.

Exhibiting high performance with long-term stability, the small size of the NAP-520 makes it particularly suitable for portable instruments such as disposable “badge” type gas detectors.

Nemoto’s porous electrode technology enables accurate gas detection with high sensitivity. The mechanical design of the sensor gives optimum gas diffusion characteristics, and the hermetically sealed enclosure prevents costly electrolyte leakage.
