safety, driven by dedication, and delivering innovation.
YHSP-SA is an electronic liquid leak point sensor engineered for chemical-family specific detection of organic solvent and oil leaks. It does not respond to water and detects leaks within 2 to 60 seconds, depending on the chemical. The replaceable YHS-FS sensor cartridge supports fast on-site replacement and a reusable sensor body, reducing maintenance costs. Use it with either a YHSM-01S-A (1-channel) or YHSM-04S-A (4-channel) leak detection control module.

๐ง Electronic leak point sensor for organic solvents & oils, YHSP-SA
Chemical family detection for organic solvents and oils, with a replaceable YHS-FS sensor cartridge.
YHSP-SA is an electronic leak point sensor that detects organic solvents and oil-based chemicals without responding to water. It detects leaks within 2 to 60 seconds, depending on the chemical, and is suitable for indoor and outdoor use around factories, tanks and piping.
Key Features
๐งช Optimized Detection by Chemical Family
โข Designed for chemical-family specific detection of organic solvents and oils without responding to water. Typical detection media include THF, acetone, IPA, toluene, MEK and xylene.
โก๏ธ Fast Response
โข Detects leaks within 2 to 60 seconds, depending on the chemical.
๐ง Replaceable Sensor Cartridge
โข The YHS-FS sensor cartridge is replaceable. The sensor body is reusable, supporting fast on-site cartridge replacement and reduced maintenance costs.
๐ช Control Module Integration
โข Use YHSP-SA with either the YHSM-01S-A (1-channel) or YHSM-04S-A (4-channel) leak detection control module for system operation.
๐จ Simple 2-Wire Connection
โข Observe the correct polarity when connecting the sensor: White: positive (+); Black: negative (-).
YHSP-SA is a practical solution that combines chemical-family specific detection and maintenance efficiency for building an organic solvent & oil leak monitoring system.
