Product Detail

Product Description

The product has fast response speed, high measurement accuracy, good stability and repeatability, simple operation, and can withstand the test of harsh environments. The core components adopt world-renowned brand gas sensors, which have good gas sensitivity and excellent repeatability, and respond quickly. They are easy to use and maintain. In conclusion, CA228 has high stability, high accuracy, and high intelligence.

Robust Protection

Made of high-strength materials which are compressive, anti-drop, wear-resistant, and corrosion-resistant. Features splash-proof, dust-proof, and explosion-proof designs certified by the national designated center.

Flexible Communication

Can connect to hosts like CA2100D with RS485 signal electrical isolation. Outputs standard 4-20mA current signals or converts to RS485 digital signals for host display.

The product can support customized detection of hundreds of gases such as oxygen, hydrogen sulfide, carbon monoxide, chlorine, ammonia, etc. It can also customize sound and light alarm functions. When the gas concentration reaches the set value, the equipment emits an alarm sound of at least 70dB, allowing users to respond and handle quickly. CA228 is a basic product. If customized with functions such as real-time display, Model CA228F or CA228-D can be recommended.

More importantly, the product can be directly interconnected with our innovative IoT platform through NB-IoT technology, abandoning the traditional alarm controller layout mode and greatly reducing equipment procurement costs. At the same time, the IoT platform is built using a configuration UI mode, and platform adjustment, product operation and maintenance, customized output on the large screen, and report generation all do not require code programming or hiring professional IT personnel. Ordinary employees can quickly get started with the operation; moreover, the entire IoT platform can be directly deployed on your servers, making your digital transformation more fearless.

Frequently Asked Questions

What gases can the CA228 gas detector detect?

The CA228 supports customized detection of hundreds of different gases, including common gases like oxygen, hydrogen sulfide, carbon monoxide, chlorine, and ammonia.

What signal outputs does the CA228 support for communication?

The detector can output sampled values through control voltage to control a standard 4-20mA current signal, or convert them into RS485 digital signals via a serial port to upload to a host (such as the CA2100D) with RS485 signal electrical isolation.

Does the CA228 include local alarm capabilities?

Yes, it supports customized sound and light alarm functions. When the gas concentration reaches the pre-set threshold, the device will emit an alarm sound of at least 70dB to prompt quick response.

How durable is the CA228 in harsh industrial environments?

The CA228 is built from high-strength materials designed to be compressive, anti-drop, wear-resistant, and corrosion-resistant. It offers splash-proof, dust-proof, and explosion-proof protection, certified by the national designated inspection center.

Can the CA228 connect directly to IoT systems?

Yes, it can interconnect directly with our IoT platform using NB-IoT technology, eliminating traditional alarm controllers. The platform features a no-code configuration UI for easy operation and can be deployed directly on your own servers.

What should I choose if I need a real-time display?

The standard CA228 is a basic model. If you require real-time display or other customized display functions, we recommend choosing the Model CA228F or CA228-D.
