Fixed Gas Detector Pump NH3 Wastewater Treatment Plant Confined Space Toxic Gas Online Monitoring
YT-98H/YT-98H-A Fixed Gas Detector is a built-in pump-suction single & multi gas detector with IECEx and ATEX certification. Featuring non-contact magnetic wand design, it can be installed and operated in explosion-proof areas and Oil & Gas industry. In addition to 3-wire 4 to 20-mA output with relays, it offers HART and Modbus protocols, making it compatible with most control systems. With optional wireless function, operators can view data on laptop, mobile phone or cloud system remotely.
YT-98H can detect the concentration of CO2 and NH3 simultaneously. It operates in environments of -20°C to 50°C, making it suitable for installation in freezers, cold storage and other environments to detect ammonia leaks.


- Up to 6 kinds of gases can be detected simultaneously
- Reduces multiple installations in complex multi-gas environments, saving time and effort
- 2.4-inch industrial-grade high-definition color screen with 320*240 resolution and 120-degree wide viewing angle
- Optional wireless module for cloud platform data upload with SMS reminder function
- Internal suction pump for fast response
- Full software automatic verification and zero calibration functions for accurate monitoring
- Standard 4-20mA current signal, RS485 modbus signal, and relay signal output
- Standard infrared remote control for remote detector operation and settings modification
- Optional sound and light alarm function
