YT-98H/YT-98H-A Fixed Gas Detector
Built-in pump-suction single & multi-gas detector with IECEx and ATEX certification. Features non-contact magnetic wand design for safe operation in explosion-proof areas and oil & gas industries. Offers 3-wire 4-20mA output with relays, HART, and Modbus protocols for compatibility with most control systems.
Advanced Pump Technology
Built-in high-suction vacuum pump with over 12,000 hours continuous operation. Provides faster response detection compared to traditional diffusion sampling. Suitable for normal open areas or underground confined spaces to detect gas concentration at high altitudes, ensuring personnel safety.
Display & Interface
2.4-inch high-definition color screen with simulated menu icons. Supports Chinese and English language switching. Capable of detecting up to six gases simultaneously with settable high/low alarm values and unit conversion.
Control & Output Options
Infrared remote control operation without opening the cover. Standard 3-wire 4-20mA, RS485, and 1 group relay output (up to 2 groups optional). External sound and light alarm available. Optional 0-10V, 0-5V, 1-5V outputs.
Protection & Safety Features
Explosion-proof, lightning protection, anti-static, surge protection, waterproof with IP65 rating. Optional: sound and light alarm (integrated or external), water vapor filter cartridge, automatic dehumidification drainage systems, and high-temperature flue gas pretreatment system.
Wireless Connectivity
Wireless transmission options: 2km, 5km, 8km unobstructed range or 2G/4G wireless signal transmission (unlimited distance). Cloud platform enables remote data monitoring, record storage, real-time viewing, and multi-user management.
