Why is the CMS 300 Series CO Gas Sensor the Optimal Choice?

Posted on: 08/05/2025

In ventilation systems, parking garages, high-rise buildings, and confined areas, Carbon Monoxide (CO) is a hidden hazard that can severely impact human health.

Installing a CO gas sensor is essential to monitor and warn of toxic gas concentrations promptly. Among the many devices on the market, the CMS 300 Series stands out as the optimal solution thanks to its combination of high accuracy, durability, and flexible integration.

1. Introduction to the CMS 300 CO Sensor

The CMS 300 is a specialized sensor designed to detect and warn of CO gas in the air. It is suitable for indoor environments where CO accumulation is a risk, such as:

Parking garages
Shopping centers
HVAC systems
Factories and enclosed warehouses
Generator rooms, pump stations, and technical rooms

Model CMS300 Carbon Monoxide Transmitter and Switch

2. Outstanding Advantages of the CMS 300 Series

High accuracy and fast response

The CMS 300 features a high-quality electrochemical sensor that can detect low CO concentrations within seconds. It delivers stable, reliable, and real-time results.

Durable design for harsh environments

The sensor housing is made of corrosion-resistant material and meets IP65 protection standards, ensuring stable operation in humid, dusty, or poorly ventilated areas.

Flexible system integration

The CMS 300 supports analog signals (0-10V, 4-20mA) and Modbus RTU, making it easy to integrate into central monitoring systems, control panels, or building management systems (BMS).

Smart alarm functions

Equipped with a built-in buzzer and LED indicators, the CMS 300 provides immediate alerts without the need for additional monitoring devices.

Low operating costs

With a long sensor lifespan (up to 5 years) and minimal calibration requirements, the CMS 300 helps optimize maintenance and replacement costs for businesses, building managers, and industrial zones.

3. Common Applications of the CMS 300 CO Sensor

Automatic ventiation systems controlled by CO concentration in parking garages
Integration with fire alarm and toxic gas alert systems in buildings
Protecting the health and safety of personnel working in confined spaces
Energy optimization by controlling ventilation fans based on actual gas loads
