HT-62 fully automatic smoke detector

1、 Execution standards

JJG968-2002 Smoke Analyzer

2、 Purpose:

This instrument uses the positioning electrolysis method to determine harmful gases in the flue. It can be widely used in environmental monitoring, labor protection, industrial hygiene, factories and mines to determine the concentration of harmful gases in pipeline pollution sources and evaluate and calibrate the accuracy of continuous flue gas measurement instruments.

3、 Performance characteristics

1. Mold forming process, simple operation, small size, light weight, compact structure, easy to carry.

2. Integrated oxygen content sensor, displaying oxygen content and calculating excess air coefficient.

3. Automatically memorize the parameters entered each time, and use them automatically the next time the device is turned on, achieving one click sampling.

4. Adopting imported wide temperature OLED display screen, automatic backlight illumination, and a good human-machine interface with vivid graphics and text, it eliminates the trouble of adjusting contrast and can work in ultra-low temperature and low light environments.

5. Using imported flow sensors, the working flow rate of the sampling pump is automatically monitored, and the power of the sampling pump is automatically adjusted according to the pressure inside the flue, so that the sampling flow rate remains constant.

6. The use of imported pressure sensors and imported electrochemical sensors provides more accurate measurement results. The electrochemical sensing and signal module are integrated, and the replacement of the sensor does not require calibration. It also has temperature and linear compensation and cross interference correction functions to ensure measurement accuracy.

7. It can measure the emission concentrations and converted concentrations of various harmful gases such as SO2, NO, NO2, CO, CO2, H2S (optional), etc.

8. Equipped with a large capacity rechargeable battery, it can work continuously for more than 8 hours without AC power. After connecting to AC power, the instrument automatically charges the battery and has a real-time clock.

9. Equipped with a handheld flue gas preprocessor, it can perform dust removal, dehydration and other treatments on the flue gas to ensure long-term measurement accuracy (simple sampling tubes can damage the sensor, causing premature aging of the sensor, and gases such as SO2 are absorbed by condensed water, resulting in low measurement results).

10. Adopting a small volume, high flow flue gas diaphragm sampling pump and electronic flowmeter combination to achieve adjustable flow and constant current sampling.

11. Collect and measure various gas, smoke temperature, flow rate, smoke flow rate and other operating parameters, with one machine for multiple purposes.

12. The upper exhaust design effectively solves the blockage caused by lower exhaust and the damage caused by exhaust gas discharged into the instrument.

13. Linear calibration of various parameters of the instrument can be directly performed through a waterproof keyboard. Password input is required for instrument maintenance and calibration to ensure the safety of instrument parameters.

14. Real time display of direct reading parameters such as dynamic pressure, static pressure, temperature, smoke temperature, flow rate, flow rate, and rotational speed, and automatic measurement of atmospheric pressure.

15. The instrument comes with a built-in storage function that can store 10000 sets of data, and can be connected to RS232 for on-site printing of sampling reports using a micro printer. USB storage or memory card storage can also be used to connect to a computer and print data reports
