1, with multiple functions, can measure parameters such as smoke, lampblack, moisture content, flow rate, dynamic pressure, static pressure, smoke temperature, lampblack and flue gas (such as O2, s O2, NO, NO2, CO, CO2 and H2S).
2, AC and DC dual-use, equipped with large-capacity ZD- 12 DC power box, can work in places without AC power supply, working time is more than 8 hours.
3. Equipped with intelligent flue gas pre-processor, it can filter and remove dust, heat and dehydrate the flue gas, which makes the measurement data more accurate and the instrument safer.
4. Automatically store the monitoring data for query and printing, and the data storage capacity is 1 10,000 groups. You can use a micro printer to connect RS232 interface to print the sampling report on site, or you can use USB memory or memory card to store and connect to a computer to print the sampling report.
5. Automatically remember the last input monitoring parameters, and give priority to the next startup to realize one-click sampling.
6. Unique drying cylinder, with three-in-one design of drying, filtering and backflow prevention, can efficiently dry moisture and filter dust, reduce the influence of downward suction on flow, and realize long-term clean-free operation.
7, wide temperature LCD display, adjustable backlight and brightness, Chinese man-machine dialogue menu display, illustrated, simple and clear, users rely on rich online operation tips, direct operation.
8. Multi-level photoelectric isolation and multi-CPU fault-tolerant structure to overcome electrostatic interference and electrostatic breakdown.
9. The exhaust adopts upward design, which effectively solves the blockage caused by downward exhaust and the damage to the instrument caused by exhaust.
10, which can automatically correct parameters such as temperature and pressure. The standard temperature and pressure data can be directly read out, and it has power-off protection function, and automatically enters the sampling state before power-off after incoming call.
1 1. The parameters of the instrument can be linearly calibrated directly through the waterproof keyboard. Password must be entered for instrument maintenance and calibration, and instrument parameters are safe.
12, a unique air cooling system. When the temperature in the instrument is higher than the set temperature, the air cooling system automatically turns on and the instrument works normally.
13, real-time display of direct reading dynamic pressure, static pressure, temperature, smoke temperature, flow rate, speed, moisture content and other parameters, automatic measurement of atmospheric pressure.
14, with imported pressure sensor and imported electrochemical sensor, the measurement result is more accurate. The electrochemical sensor and signal module are integrated together, and the sensor does not need calibration, and has the functions of temperature and linearity compensation, cross-interference correction and test accuracy.
15, adopting corrosion-resistant large-flow adjustable-speed smoke sampling pump and electronic flowmeter, with fast response and high tracking efficiency. The flue gas pipeline adopts non-adsorption tetrachloroethylene pipeline, and the electronic flowmeter is used for constant current sampling, which improves the accuracy of measurement results.
16. The instrument is equipped with a rechargeable battery, which can be used to save data when the AC power supply is cut off, automatically resume sampling when the AC power comes in, automatically deduct the power-off time in the sampling process, and provide users with information on the power-off time.
