YT-95H Fixed O3 Gas Detector with Electrochemical Sensor IP65 Rated and RS485 Modbus Output for Industrial Monitoring
YT-95H Fixed Ozone (O3) Gas Detector
A cost-effective, 24/7 continuous gas transmitter for ozone detection, featuring triple signal outputs (4-20mA, RS485 Modbus, relay) and rugged explosion-proof construction.
The YT-95H is a fixed gas detector purpose-built for ozone (O₃) monitoring in industrial environments. It combines 3-wire 4-20mA analog output, RS485 Modbus communication, and a relay contact in one unit, ensuring easy integration with DCS, PLC, and gas control panels. Optional add-ons include a sound-light alarm, infrared remote control, and wireless transmission (LoRa/4G). The detector is housed in die-cast aluminum, rated IP65 and Ex d IIC T6 Gb, making it suitable for long-term deployment in harsh conditions.

- Continuous online monitoring - Real-time concentration display with user-adjustable high/low alarm thresholds.
- Optional audible-visual alarm - Sound level >90 dB, clearly noticeable even in noisy industrial settings.
- Infrared remote control - Adjust alarm setpoints, perform zero calibration, or change device address without opening the housing - safer and faster.
- Triple output interface - Integrated 4-20 mA (analog), RS485 Modbus (digital), and relay output - compatible with most control systems.
- Relay-driven linkage - Directly activates external horns, strobe lights, exhaust fans, or shut-off valves for automated hazard response.
- Wireless ready (optional) - LoRa or 4G modules enable remote data viewing on mobile phones or laptops.
- PC software support - For remote monitoring, data logging, and historical record management.
- Industrial-grade ruggedness - Die-cast aluminum housing, IP65 (dust-tight and water-resistant), and Ex d IIC T6 Gb explosion-proof certification.
- Stable and low drift - High repeatability and minimal zero shift for long-term reliable operation.
| Industry / Application | Specific Use Cases |
|---|---|
| Water & wastewater treatment | Disinfection and oxidation processes - monitor O₃ in treatment rooms, generator areas, and contact chambers to protect workers and equipment. |
| Food & beverage processing | Surface sanitation, bottle rinsing, cold storage deodorization - ensure safe O₃ levels in filling rooms, packaging lines, and cold rooms. |
| Chemical & pharmaceutical manufacturing | Ozone as oxidizer or reagent - detect leaks in production areas, storage rooms, and around ozone generators. |
| Semiconductor & electronics | Wafer cleaning and surface treatment - install detectors in cleanrooms and tool exhaust lines. |
| Pulp & paper bleaching | Ozone replaces chlorine for bleaching - monitor in bleaching towers, storage tanks, and ventilation ducts. |
| Indoor air quality (commercial buildings) | Ozone generators for odor control - maintain safe levels in HVAC systems, parking garages, and industrial kitchens. |
