The GIR-3000 is a fixed infrared hydrocarbon detector produced by GASTRON. The following is a detailed introduction: **Performance Features of [GASTRON GIR-3000](http://www.cwlyautomation.com/product/1736.html "GASTRON GIR-3000")** **Diverse Gas Detection: **It can continuously detect various gases such as hydrocarbon gases (e.g., LNG, LPG, methane, butane, etc.), CO₂, CO, N₂O, etc. It is widely applicable to hazardous areas like industrial plants and gas storage facilities, effectively preventing serious accidents caused by gas leaks. Advanced Detection Principle: It adopts the infrared detection principle, featuring high precision, high sensitivity, and rapid response. It can operate in an oxygen - free environment and detect gas leaks accurately and promptly. **Long Service Life: **The sensor life can reach more than 5 years, reducing the cost and trouble of frequent sensor replacement and ensuring long - term stable operation. **Low Maintenance Cost:** It is maintenance - free. The built - in microprocessor's self - diagnostic function can automatically detect the operating status of the instrument, promptly identify faults and issue alarms, reducing maintenance workload and cost. **Convenient Operation:** It uses a magnetic rod for automatic calibration and program setting. There is no need to open the instrument housing, and a single person can complete calibration and maintenance. The operation is simple and convenient, saving time and labor costs. **Clear and Intuitive Display:** It has a built - in backlit LCD or OLED display, which can clearly show measured gas values, operating status, alarm information, etc., enabling users to understand the instrument's operation at any time. **Technical Parameters of [GASTRON GIR-3000](http://www.cwlyautomation.com/product/1736.html "GASTRON GIR-3000")** **Measurement Range:** Usually, multiple measurement ranges are available for selection, such as 0-4000ppm, 0-100% LEL, 0-9999ppm, 0-100% vol, 0-5% vol, 0-2% vol, etc. **Output Signals:** It includes 4-20mA DC output signal, RS - 485 Modbus digital signal, HART communication signal, etc., which can be easily connected and integrated with other devices to achieve remote monitoring and data transmission. **Alarm Function:** It has a two - level alarm and a one - level fault display function. When the gas concentration exceeds the set threshold, an audible and visual alarm signal will be issued. The normal state of the alarm unit is indicated by a green LED, the alarm state by a red LED accompanied by a 95dB buzzer sound, and the fault state by a yellow LED. **Operating Power Supply:** The operating voltage is 18 - 31V DC, the normal operating voltage is 24V DC, and the maximum current is 400mA. Operating Temperature: Generally, it is -20℃ - +60℃. Some models can operate in a wider temperature range of -40℃ - +80℃. **Dimensions and Weight:** The dimensions are approximately 156X323X110 (W X H X D) mm, and the weight is about 3kg. **Protection Level:** It is explosion - proof, compliant with standards such as Ex d IIC T6, Ex d IIC Gb T4 - T6, Ex d IIC T6 Gb, etc., with a protection level of IP66/67, enabling safe and reliable operation in harsh industrial environments.
