SKU: ERANNTEX Fixed Combustible Gas Detector
The Eranntex GTYQ-MIC-600-Ex Fixed combustible gas detector adopts intrinsically safe circuit design and has passed explosion-proof certification. It has secondary lightning protection and anti-static capabilities (exceeding national standards), can withstand high-intensity pulse surge current impacts, and its high-reliability anti-reverse polarity design ensures that any reverse polarity will not damage the instrument. It complies with EMI/EMC standards and has passed national standard testing and CMC metrology certification. The implementation standards include GB15322.1-2003, GB 3836.1-2010, GB 3836.2-2010 and GB 3836.4—2010; simultaneously outputs RS485 (RTU) bus and 4-20mA standard signals, provides three relay outputs and an optional on-site audible and visual alarm. Available frequency outputs include 200-1000Hz, Hart protocol signals, 1-5V output, or wireless transmission (2-5 km/unlimited distance). Supports wired or wireless remote monitoring, and data can be uploaded to a mobile phone or transmitted via a LAN or the Internet to an environmental protection bureau, monitoring center, terminal device, or computer. Real-time concentration monitoring is achieved using free host software or a gas alarm controller.
Eranntex GTYQ-MIC-600-Ex Fixed Combustible Gas Detector Features:
● Compatible with various secondary meters, data acquisition modules, PLCs, and DCS systems, it can directly drive solenoid valves, fans, alarms, and other devices, and can also drive high-power devices via intermediate relays. The optional MIC2000 controller can simultaneously monitor up to 1000 detectors.
● Large-capacity data storage allows recording of real-time concentration values, temperature and humidity, or simply the alarm value and time. The device supports local storage or SD card storage. The standard local storage capacity is 100,000 records. Please specify when ordering for a larger capacity. SD card storage capacity is customizable. Data export and analysis are performed using free host software. Data can be viewed and deleted locally, and can be configured to automatically overwrite or not overwrite data when capacity is insufficient, as well as automatically stop recording.
●The standard infrared remote control enables operations in hazardous locations without opening the device, such as modifying alarm points, calibrating concentrations, zeroing, silencing, restoring factory settings, entering menus, viewing records, and outputting 4mA and 20mA currents (required for calibrating other data acquisition devices).
● Available in Chinese and English, the default interface is Chinese. Gas concentration units can be freely switched. Molecular weight input is not required for conventional gases, but it is automatically calculated and switched for special gases upon molecular weight input. Available units include PPM, mg/m³, Vol%, LEL%, PPHM, ppb, and mg/L.
● A 2.5-inch high-definition color screen (LCM) displays real-time concentration, time, temperature, humidity, storage status, and other information. It can simultaneously monitor 4-6 gas concentrations, along with temperature and humidity. The menu interface uses high-definition, realistic icons to display menu functions, and provides simple Chinese or English operation instructions.
● Three display modes are available: simultaneous display of multiple gas concentrations, large-font, looped display of single-channel gas concentrations, and real-time curves. Channels can be automatically or manually cycled. Display of maximum and minimum values, gas names, and historical curves can be configured.
● Automatic zero tracking prevents drift, temperature compensation, and multi-level calibration ensure compliance with national standards and local and provincial metrology bureau standards.
● Data recovery and automatic detection and prevention of concentration calibration errors prevent problems caused by improper operation.
● Features include calibration logs, maintenance logs, troubleshooting solutions, sensor life expiration reminders, and reminders for the next concentration calibration.
