Fixed 5-Gas Detector for LEL CO2 CO H2S O2 Pump Suction
Product Overview
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.
Key Features
- 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
