Control System

• Determination of particulate matter with a concentration below 20 mg/m ^{3 in} a fixed source of exhaust gas
• Gas sensor correction compensation technology: flue gas measurement has automatic correction algorithm for gas cross interference, which minimizes the influence of cross interference on measurement results and ensures measurement accuracy.
• The gas sensor range is adjustable according to the calibration range, and the range of use of the sensor is extended.
• Industrial grade embedded controller design, strong antistatic capability
• Accurate electronic flowmeter control, real-time monitoring of temperature, metering, automatic regulation of flow
• Microcomputer controlled constant speed tracking sampling, proprietary adjustment mode, fast response time
• Built-in elastic air volume to improve sampling flow stability
• With anti-back suction function, it can prevent the smoke collected after sampling is sucked out, ensuring the accuracy of sampling data.
• Real-time recording of device working status data, with sampling process power failure memory function
• Temperature compensation for flow error caused by temperature change to ensure measurement accuracy
• Multi-mode for moisture content detection: compatible with dry and wet bulb method and RC method
• Simultaneous operation with soot sampling and flue gas measurement
• With fault self-test function, it can detect the function of the instrument and prompt the fault, which is convenient for the user to maintain and use.
• Airtight automatic detection function to automatically diagnose the air tightness of the air circuit

Power system

• High-efficiency sampling pump, corrosion-resistant, flow rate up to 110Lmin, continuous operation and maintenance-free, adapt to various working conditions, with overload protection
• Precision pressure sensor with stable flow control for stable tracking with ultra-low flow rates
• Unique high-efficiency gas-water separator design, high-efficiency dehumidification, making silica gel utilization much higher than other similar instruments
• Efficient dust filtration function: The dust gas sampling gas path uses high-efficiency dust filters, which greatly reduces the failure rate of the flow sensor and sampling pump system. The filter system adopts transparent window design, easy to observe and easy to replace.

Operating system

• Intelligent software parameter calibration design
• Industrial dustproof and waterproof keyboard, easy to operate, especially suitable for harsh conditions
• With Chinese input method, it is convenient for users to input information such as sampling location
• 5.7-inch wide temperature LCD display, suitable for field temperature, good human-computer interface, making work easier
• Rich man-machine interface: RS232, USB and other interfaces, support data communication, U disk data dump output
• Pitot tube positive and negative pressure tapping nozzles are connected by silicone rubber double pipe, which has strong weather resistance, reduces pipeline connection and is easy to operate.
• Provide USB interface to export sampled data files and support upgrade of instrument motherboard program
• Easy to master real-time data with Bluetooth high-speed, low-noise micro thermal printer
• Reserved IoT module interface, expandable networking function
