Product Features

High Precision Gas Detection

The device combines electrochemical and catalytic sensing technologies to provide accurate and reliable results. Once the gas concentration exceeds the safe range, an alarm is immediately triggered to protect workers from toxic and harmful gases.

Multi-level alarm notifications: Ensuring your safety with every breath

The primary purpose of a 4 gas monitor is to alert users to any hazardous air quality environments. These instruments protect workers from unseen workplace gas hazards. 4 gas monitors warn the users of any unsafe air quality environments through audible, visual, and vibration alarms.

LCD Large Backlit Display

The device is equipped with an LCD large screen display, providing clear and easy-to-read measurements. The adjustable backlight mode allows for convenient use at night, with options for adjustable long light and automatic light modes to suit different preferences and lighting conditions.

Data Upload Function

With data storage and data upload function. It can support uploading alarm records to computer. Alarm records can be uploaded to a computer for viewing/deletion, etc. (Built-in storage is once every 10 seconds and can store 6,500 records)

Small and Exquisite

The device features a small and exquisite design with a portable buckle, allowing it to be held in one hand. Weighing just 210g and equipped with 4 sensors, it can be clipped onto the body to provide continuous personal protection.

Tripe Proof Design

The device features a tripe proof design, making it waterproof, dustproof, and explosion-proof for enhanced durability and safety. It is constructed using high-density materials with high hardness, ensuring good waterproof performance and protection against environmental elements.

Alligator Clip Design

The alligator clip design of this device ensures easy portability, allowing you to carry it with convenience wherever you go. The stainless steel crocodile clips are not only sturdy and durable but also provide a secure grip, ensuring reliable performance in various environments.

Long-Lasting Lithium Battery Power Supply

Built-in rechargeable lithium battery with a capacity of 1700mAh, a full charge can last up to 200 hours (about 8 hours for flammable gas, about 200 hours toxic gas).
