Description
Overview
GAOTek carbon monoxide gas detector has optional high-temperature high-humidity pre-treatment system will be possible to detect the smoke gas at the temperature of 1300 ℃. The detection for the gases at other temperatures can be customized. Simultaneously display the concentrations of multiple types of gases, repeatedly display the concentration of single-channel gases in large font, and display the real time curve.2.5-inch high-definition colour screen, display the information such as real-time concentration, alarm, time, temperature, humidity, storage, and so on; the menu interface adopted high-definition simulation graphics to display the function name of each menu. Standard configuration is the data storage capacity for 100, 000 entries; SD card storage function is optional configuration, real-time storage and fixed time storage are supported, or only the data of the alarm concentration will be stored; it is supported to use the local host to view, and delete data, and upload the data via RS485 interface to the computer for data analysis or printing. It is possible for the real-time monitoring via the wired or remote wireless transmission, and network transmission; three-wire system 4 to 20mA standard signal and standard bus RS485 (modbus-RTU) simultaneous output; it is compatible with secondary instrument, data acquisition module, PLC, DCS system, and it is possible to drive the related equipment. Data recovery function; in case of mis-operation, it is possible to select partial or full recovery. Multiple alarm modes, and multi-directional and three-dimensional indication alarm states. It includes: 2 sets of relay switch output, sound & light alarm (optional configuration). Alarm types include: concentration alarm, and failure alarm.
