Honeywell 2108B2021N Searchpoint Optima Plus Point Infrared Gas Detector

Honeywell 2108B2021N Searchpoint Optima Plus Point Infrared Gas Detector is a point infrared gas detector produced by Honeywell, which has the following features and advantages:

High-precision detection: Using infrared detection technology, based on the principle that most diatomic molecules and polyatomic molecules have characteristic absorption spectra in the infrared spectrum range, the type and concentration information of the gas can be accurately obtained according to the characteristics of the infrared absorption spectrum of the gas, and specific combustible gases can be detected with high precision, such as methane and other gases. The detection accuracy and sensitivity are extremely high.

Strong anti-interference ability: Infrared detection technology is not easily interfered by other gases. For example, electrochemical method and catalytic combustion method may be affected by other gases in the environment, but this detector can effectively avoid it and is suitable for complex gas environments.

Fast response: It can quickly detect and respond to changes in gas concentration, and can issue an alarm in a short time to buy time for dangerous situations such as gas leaks.

Good stability: It has stable and durable characteristics, can operate stably for a long time, reduce detection interruptions or false alarms caused by equipment failure, and reduce maintenance costs and frequency.

Safe and reliable: It usually has safety designs such as explosion-proof housing, has passed relevant safety certification, and is suitable for dangerous places with flammable and explosive gases. It can reliably detect gas conditions while ensuring its own safety.

In terms of technical parameters (specific details are subject to the product manual), the detection range varies depending on the detected gas. For example, when detecting methane, it may cover a certain concentration range of 0-100% LEL. The accuracy can reach a high level and can accurately detect slight changes in gas concentration. The response time is fast, and the general T90 response time is within tens of seconds. The operating temperature range is usually around -40℃ to +70℃, and the operating humidity range is 0-95% RH (no condensation), which can adapt to a variety of harsh environmental conditions. The output signal includes 4-20mA analog signal, digital signal (such as HART, Modbus protocol, etc.) and relay output, which is convenient for connection with various control systems and alarm equipment to achieve remote monitoring and data transmission.
