Durable Die-cast Aluminum Ozone Gas Detector for Industrial Online Monitoring
YT-95H Fixed Ozone (O3) Gas Detector
Product Overview
YT-95H is a cost-effective fixed gas transmitter specially designed for ozone (O3) detection. It integrates 3-wire 4-20mA analog, RS485 Modbus, and relay output, compatible with most industrial control systems. With optional sound-light alarm, infrared remote control, and wireless transmission (Lora/4G), it realizes 24-hour online monitoring and remote management for industrial hazardous gas sites.
YT-95H series fixed gas detector provides stable and reliable online detection for ozone (O3) and other toxic/combustible gases. It adopts standard industrial detection principles and supports high/low alarm with adjustable points. The detector features die-cast aluminum housing, IP65 protection, and explosion-proof grade Ex d IIC T6 Gb, suitable for long-term use in harsh industrial environments.
Equipped with infrared remote controller, users can set alarm points, calibrate zero, and modify addresses without opening the cover. Multiple signal outputs ensure wide compatibility with DCS, PLC, gas control panels and other systems. Relay output can directly drive external alarms, fans, and other equipment for linkage control. Optional Lora/4G wireless function supports remote real time data viewing on mobile phones and PCs.

Typical Applications
The YT-95H fixed gas detector is ideal for continuous monitoring of ozone (O3) and other gases in the following environments:
1. Water & Wastewater Treatment
Ozone is widely used for disinfection and oxidation. Monitor O3 levels in treatment rooms, generator areas, and contact chambers to prevent worker exposure and equipment corrosion.
2. Food & Beverage Processing
Ozone is used for surface sanitation, bottle rinsing, and cold storage deodorization. Fixed detectors ensure safe levels in filling rooms, packaging lines, and cold rooms.
3. Chemical & Pharmaceutical Manufacturing
Ozone as an oxidizer or reaction agent. Monitor leaks in production areas, storage rooms, and around ozone generators.
4. Semiconductor & Electronics Industry
Ozone used for wafer cleaning and surface treatment. Install detectors in cleanrooms and tool exhaust lines.
5. Pulp & Paper Bleaching
Ozone replaces chlorine for bleaching. Monitor in bleaching towers, storage tanks, and ventilation ducts.
6. Indoor Air Quality (IAQ) in Commercial Buildings
Ozone generators used for odor control. Ensure levels stay within safe limits in HVAC systems, parking garages, and industrial kitchens.
