Brief Description

The FIX800 series online gas detector uses a high-performance intelligent gas sensor, which is a high-performance instrument that can continuously monitor gas online. The overall explosion-proof structure of the detector has high sensitivity and precision. The detector can realize real-time concentration display on the computer through the gas alarm controller and monitoring management software. It can also transmit real-time monitoring data and alarm status to the safety control center through the optional wireless module.



Main Features

◆ High-performance intelligent sensors, with a service life of more than 2-3 years.

◆ Using embedded 32-bit ultra-low power microprocessor, with short response time, small detection error and high resolution.

◆ Equipped with infrared remote control, menu operation can be carried out through the remote control, which can realize the operation without opening the cover in dangerous situations.

◆ Intelligent temperature, humidity and zero point compensation algorithm, full software automatic calibration function for target points above level 2 to ensure the accuracy of the measurement results; automatic detection of the working status of each sensor and component when it is turned on.

◆ 2.3-inch full-color display, large and clear background light can display measurement information under any lighting conditions; easy-to-understand UI color icon menu, 4-button navigation friendly user interface.

◆ Support free switching between PPM and mg/m3, %VOL and mg/L concentration units, and free switching between Chinese and English operation interface.

◆ Real-time data transmission, can accurately send out local and remote wireless alarm notifications in a variety of alarm methods (optional).

◆ First-class mechanical design, the air chamber adopts military-quality high-strength aluminum profiles, wear-resistant and corrosion-resistant, suitable for complex and harsh industrial environments, and reasonable and scientific air chamber design to ensure the accuracy of real-time sensor monitoring.

◆ Automatic storage, storage interval can be customized, 300,000 groups of data with date and time identification can be stored, if TF memory card is optional, it can store more than 10 million groups.

◆ The short-distance RTU wireless transmission method or the GPRS wireless transmission method of unlimited distance anywhere can transmit real-time detection data and alarm status to the security center through the built-in wireless module function (optional).

◆ The explosion-proof grade is Exd II CT6, certified by the National Explosion-proof Electrical Inspection Center.
