Fixed 5-Gas Detector for LEL CO2 CO H2S O2 Pump Suction
The YT-98H/YT-98H-A Fixed Gas Detector is a built-in pump-suction single & multi gas detector with IECEx and ATEX certification. Featuring a non-contact magnetic wand design, it's suitable for installation and operation in explosion-proof areas and the Oil & Gas industry. The device offers 3-wire 4 to 20-mA output with relays, HART, and Modbus protocols for compatibility with most control systems. Optional wireless functionality allows remote data viewing on laptops, mobile phones, or cloud systems.
- Detects up to 6 gases simultaneously, reducing multiple installations in complex environments
- 2.4-inch industrial-grade high-definition color screen (320*240 resolution, 120° viewing angle)
- Optional wireless module for cloud data upload with SMS alerts and unlimited transmission distance
- Internal suction pump for fast response times
- Full software automatic verification and zero calibration functions for reliable monitoring
- Standard 4-20mA current signal, RS485 modbus signal, and relay signal output
- Infrared remote control for detector operation and settings modification
- Optional sound and light alarm function when reaching alarm points
