Lightweight Diffusion Ozone Gas Detector

With Sound+Light+Vibration Alarm, IP65

A mini-size, low-cost, high-accuracy portable diffusion gas detector for ozone (O₃) monitoring. Measures from 0–50ppm with 0.1ppm resolution using an electrochemical sensor. Features LCD dot matrix display, sound, light & vibration alarm, 100 event logs (standard), optional 100,000 data logging, and a 2500mAh rechargeable battery for up to 14 hours continuous operation. Explosion-proof Ex ia IIC T4, IP65 rated. Ideal for water treatment, food processing, and industrial hygiene.

The YT-1200H-S series is a mini-size, lightweight portable multi-gas detector designed for hazardous environments. Using diffusion sampling, it requires no pump, making it simple and maintenance-free. The detector is housed in a strong, durable ABS + leather case with an alligator clip and protective silicone cover, suitable for various workplace conditions.

Taking ozone (O₃) as an example, the instrument uses an electrochemical sensor to measure concentrations from 0–50ppm with a resolution of 0.1ppm. It provides triple alarm (sound, light, vibration) with an ultra-high buzzer, and features a monochrome dot matrix LCD (128×128) with adjustable backlight that automatically turns on during alarm.

The detector comes standard with 100 event records (viewable on device) and supports optional data logging of up to 100,000 readings with adjustable interval (10–3600 seconds). Data can be exported to a PC via supplied software. One-key factory reset simplifies restoration.

Powered by a 3.7V 2500mAh rechargeable lithium battery, it operates continuously for 14 hours (with 4-gas combination) or up to 200 hours (without LEL sensor). Charging time is 4–6 hours.

Ozone is a pale blue gas with a pungent odor. It is used for water disinfection, air purification, food processing, and industrial bleaching. However, ozone is a strong oxidizer and can be harmful to human health at elevated concentrations. Short-term exposure may cause throat irritation, coughing, and reduced lung function. The YT-1200H-S helps monitor O₃ levels to ensure safety in workplaces where ozone is generated or used.

• Water & wastewater treatment plants – Ozone disinfection byproduct monitoring.
• Food & beverage processing – Ozone sanitation in bottling, cold storage, and surface cleaning.
• Pharmaceutical manufacturing – Cleanroom and sterilization area monitoring.
• Indoor air quality – Offices, public buildings with ozone-generating equipment.
• Industrial hygiene – Worker exposure monitoring in printing, bleaching, and chemical industries.
• Laboratories – Fume hood verification and research areas.
