GTQ-DX401 Multi-Gas detector is an intelligent detection equipment of BOSEAN brand. It adopts advanced integrated circuit and intelligent technology design, uses natural diffusion sampling, and uses high-quality gas Sensor modules for detection. It has the characteristics of high Sensitivity and good repeability. It is easy to use and maintain, and can meet the requirements of high reliability of detection equipment in industrial sites.
1. Adopt user-friendly GUI operation interface and color LCD display. 2. Adopt advanced micro-power technology Sensor. 3. It has the function of LCD on-site display of gas concentration, which is convenient for on-site personnel to understand the situation in time. 4. Indicate normal, low alarm, high alarm, and malfunction through the indicator light. 5. The shell has been inspected by the state-designated explosion-proof product inspection unit and obtained the explosion-proof certificate. 6. Using semiconductor nano process ultra-low power 32-bit microprocessor and 24-bit ADC data collection chip. 7, can simultaneously detect gas, oxygen, carbon monoxide, hydrogen sulfide four gases (can be customized according to demand). 8. Support PPM,% VOL, mg/m ³, μmol/mol unit switching. 9. Sensor replacement does not require on-site calibration, and Sensor key parameters are automatically identified. 10. Support Chinese and English display. 11. Sensors have up to 5 target point calibrating functions to ensure measurement accuracy and linearity. 12, with two alarm settings and two sets of relays passive signal output. 13. Standard RS485 signal, using standard MODBUS RTU protocol, transmission distance < 1km. 14. Equipped with overvoltage protection, lightning protection, short circuit protection, reverse connection protection, anti-static interference, anti-magnetic field interference and other functions, and with automatic recovery function.
The detector uses natural diffusion for gas sampling. The gas in the environment enters the detector by diffusion and contacts the internal sensitive component - the high-quality gas Sensor module. The Sensor converts the gas concentration signal into an electrical signal, and after advanced microprocessor and ADC chip for data processing, the concentration value is finally displayed on the LCD screen, and the sound and light alarm and relay output are triggered according to the preset threshold.

GB 12358-2006 "General technical requirements for workplace environment Gas detection alarms", GB/T 3836.1-2021 "Explosive environment - Part 1: General requirements for equipment", GB/T 3836.2-2021 "Explosive environment - Part 2: Equipment protected by explosion-proof enclosure" d ", GB/T 3836.31-2021" Explosive environment - Part 31: Equipment protected by dust-proof ignition enclosure "t"
1. Select the appropriate installation location and interface according to the installation method (Wall-Mounted or Pipeline) and thread size (NPT). 2. Using a 2x0.75mm Shielding cable, connect the DC (24 +/- 3.6) V power supply through the M20x1.5 or G1/2 terminals. 3. After power on, the device starts, and parameters are set (such as alarm threshold, unit selection, etc.) through the GUI operation interface and color LCD screen. 4. The equipment enters the normal working state, continuously detects the environment gas through natural diffusion, and displays the gas concentration, type, unit and working status in real time on the LCD screen. 5. When the detected gas concentration reaches the preset alarm value, the device triggers the sound and light alarm, and outputs the switch signal through the relay.
• Please ensure that it is used under the environment conditions specified by the equipment: Working Ambient Temperature -40 ℃~ 70 ℃, Humidity ≤ 95% RH (no condensation condensation), Detection gas pressure 86kPa~ 106kPa. • Please pay attention to explosion-proof requirements during installation to ensure that the wiring is firm and the cable meets the specifications (2x0.75mm Shielding cable). Equipment has a variety of protection functions (such as overvoltage, lightning protection, short circuit, reverse connection protection, etc.), but it should still be avoided in environments where extreme external conditions, man-made damage or natural disasters may cause damage. • Relay load capacity is 30VDC 2A/125VAC 1A, do not overload when connecting external devices. The explosion-proof mark of the equipment is Ex db IIC T6 Gb/Ex tb IIIC T80 ° C Db, and the explosion-proof grade is IP66. Please use it in a place that meets the explosion-proof requirements.
