Pump-Type HCL Gas Detector Wall Mounted Fixed Gas Detector with High Accuracy Continuous Monitoring
Hydrogen chloride (HCL) is a colorless, irritating, corrosive, and asphyxiating gas that is both volatile and unstable.
High-purity HCL gas is widely employed in the electronics industry. The gas has a suffocating odor and is highly irritating to the upper respiratory tract, with corrosive effects on eyes, skin, and mucous membranes. Continuous HCL concentration monitoring is essential to prevent leaks that could endanger personnel safety.
Maximum allowable concentrations: China (MAC) 15 mg/m³ (9.2 ppm); US TLV-C 7.5 mg/m³ (4.6 ppm).
Due to HCL's volatile and unstable nature, pump-type detectors that actively draw gas samples provide faster and more reliable detection.
The YT-98H is a built-in pump-suction single and multi-gas detector featuring IECEx and ATEX certification with non-contact magnetic wand design. Suitable for installation and operation in explosion-proof areas and the oil & gas industry, it offers 3-wire 4-20mA output with relays, plus HART and Modbus protocols for compatibility with most control systems. Optional wireless functionality enables remote data viewing on laptops, mobile phones, or cloud systems.
- Simultaneous detection of up to 6 different gases
- Reduces multiple installations in complex multi-gas environments, saving time and resources
- 2.4-inch industrial-grade high-definition color screen with 320*240 resolution and 120-degree viewing angle
- Optional wireless module for cloud platform data upload, environmental protection bureau integration, and SMS alerts with unlimited transmission distance
- Internal suction pump for fast response times
- Full software automatic verification and zero calibration functions for enhanced accuracy and reliability
- 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
