1. Background: The Entry-Exit Inspection and Quarantine Bureau should randomly inspect and test the goods entering and leaving the containers at each port. Due to the environmental location, various possible toxic and harmful gases remain, which poses a threat to the life and safety of inspectors. This set of plans perfectly responds to this testing requirements.

two Selected model: MIC-600-3-A detector built-in data storage, on-site sound and light alarm

3. Monitoring factors: carbon monoxide CO, hydrogen sulfide H2S, formaldehyde CH2O

4. Sensor: Electrochemistry

Description: Using a mobile remote control vehicle as a detector carrier, the sensor gas chamber is separated from the surface head, and the gas chamber is placed at the top to directly detect the content of harmful gases in the space. If it exceeds the preset alarm point, a sound and light alarm will be made on the spot. Work, and the data is stored in real time and in the instrument to provide data reference for the later stage.

Case Product Introduction

MIC-600 is suitable for detecting gas concentrations in pipelines or in confined spaces and atmospheric environments; gas leaks and various background gases with high concentrations of nitrogen or oxygen, with more than 500 types of detection. The robust and durable explosion-proof shell and fluorocarbon paint surface treatment process are suitable for various dangerous places and corrosive environments, and are wear-resistant.

Product Features:

★ 1 to 6 gases can be detected at the same time, and the unit can be switched freely.

★ Diversified communication methods.

Real-time monitoring can be carried out through wired or wireless remote transmission and network transmission; standard bus RS485 (modbus-RTU) and 4 to 20mA standard signal are output at the same time; optional frequency output 200-100 0Hz, Hart protocol signal, 1 to 5V output, wireless transmission (2 to 5 kilometers or unlimited distance); compatible with secondary instruments, data acquisition modules, PLC, DCS systems, can drive related equipment.The optional MIC2000 controller can monitor 1000 detectors at the same time.

★ Infrared remote control.

Standard infrared remote control, one-button operation can be carried out through the infrared remote control function key, which can realize open-free operation in dangerous situations, such as: modifying alarm points, concentration calibration, zero calibration, silencer, factory recovery and other functions.

★ Rich human-computer interface.

2.5-inch high-definition color screen, displaying real-time concentration, alarm, time, temperature, humidity, storage and other information; the menu interface uses high-definition simulation graphics to display the function names of each menu.

★ Large-capacity data storage function, supporting multiple storage methods.

Standard 100,000 data storage capacity; optional SD card storage function, support real-time storage, timed storage, or only store alarm concentration data; support local viewing and deletion of data, and can also be uploaded to the computer through RS485 interface Conduct data analysis or printing.

★ High-temperature gas detection (optional).

Optional high-temperature sampling cooling filter handle or high-temperature and high-humidity pretreatment system can detect flue gas at a temperature of 1300 degrees. Gas detection at other temperatures can be customized.

★ Three display modes can be switched.

Displays a variety of gas concentrations at the same time, the large font cycle displays the concentration of single-channel gas, and the real-time curve is displayed.

★ Graphical display reflects the trend of gas concentration changes over a period of time in the form of a curve.

● With the data recovery function, you can choose to restore part or all of it, avoiding the worries caused by misoperation.

● You can set whether to display the maximum, minimum and average values.

● High-precision temperature and humidity measurement (optional).

● Multiple alarm methods, multi-dimensional three-dimensional indication alarm status when alarming.

Includes: 3 sets of relay switching output, sound and light alarm, display visual alarm. Alarm types include:

concentration alarm, undervoltage alarm, fault alarm.

● Multiple alarm mode settings: low alarm, high alarm, interval alarm, weighted average alarm.

● Misoperation identification function: Concentration calibration misoperation is automatically recognized and prevented, which can avoid adverse causes caused by human factors.

● Zero automatic tracking, long-term use is not affected by zero drift.

● Multi-level calibration of the target point to ensure the linearity and accuracy of the measurement.

● Chinese and English interfaces can be selected.

● Wide working temperature: -40 to +70℃, support temperature compensation.

● Log.

Record calibration log, repair log, fault record, fault solution countermeasures, sensor life expiration reminder, next concentration calibration time reminder function.

● Benan circuit design, explosion-proof, with second-level lightning protection and anti-static ability. Meet national standards and resist high-intensity pulse surge current shock. It has the function of anti-reverse connection. Comply with EMI and EMC standards.

Application place

It is mainly used in petroleum, chemical industry, medicine, environmental protection, flue gas analysis, air treatment and other places that need to be fixed installation and online detection of gas concentration.
