RAEAlert EC is a toxic gas detector that adopts modular design, intelligent sensor detection technology, integral explosion-proof (d) structure, and fixed installation method. The standard configuration includes a dot matrix LCD display, a three wire 4-20mA analog and RS485 digital signal output, and optional modules such as programmable switch output. Customized products are provided according to user needs, and functions such as output signal fine-tuning are also supported to facilitate system networking and maintenance. Can detect various toxic and harmful gases such as CO, H2S, O2, SO2, Cl2, NH3, HCN, NO, NO2, PH3, ClO2, ETO, etc.

Main Features
Intelligent EC sensor, using intrinsic safety technology, can support multi gas and multi range detection, and can provide customized products according to user needs. It can achieve sensor interchangeability, offline calibration, and zero point self calibration without the need for tools
Intelligent temperature and zero compensation algorithms enable instruments to have better performance
• Has good selectivity, avoiding interference from other gases on the detected gas
Multiple signal outputs, which can be easily connected to industrial control systems such as PLC/DCS, and can also be used as standalone control
• Large dot matrix LCD display, supporting both Chinese and English interfaces
• No need to open the lid, infrared remote control operation, single person maintenance
Local alarm indication, integrated sound and light alarm (optional)
The instrument has over range and reverse polarity protection, which can avoid the danger caused by improper human operation
Rich electrical interfaces for users to choose from
Certified by ATEX, UL, CSA, etc., with international high-end quality
