Product Description
SP-15A-00 Gas Sensor for LPG Detection Description
The SP-15A is a tin dioxide semiconductor gas sensor which has a high sensitivity and excellent selectivity in propane/ butane detection.
The SP-15A has also a significant feature in good stability after exposure to silicone compounds. Using the SP-15A, the most reliable LPGas leak detection can be achieved.
SP-15A-00 Gas Sensor for LPG Detection Application
• Home gas leak detector
