NAP-78SU is a gas sensor developed to detect incomplete combustion of gas water heaters. It can directly detect exhaust gas at about 200 ° C and is sensitive to carbon monoxide and hydrogen.A bridge circuit is built on the board, and it can be adjusted to any zero point with a variable resistor.
- Measurement range
- Incomplete combustion exhaust gas within 1% * Contains 0.5% hydrogen
