1. Product overview

JCH-1000B air dioxin sampler is used to collect samples of semi-volatile organic compounds (SVOC) such as polycyclic aromatic hydrocarbons, dioxins, and polychlorinated biphenyls in ambient air.

2. Product Features

1. Adopt imported wide temperature OLED display screen, Chinese menu with good man-machine interface with pictures and texts, eliminating the need for The hassle of adjusting
contrast , works in ultra-low temperature environments.
2. The flow control adopts high-precision imported sensor, which has good flow stability and high sampling accuracy, automatically detects the sampling
flow, automatically controls constant current sampling, and compensates for flow fluctuations caused by changes in voltage and resistance.
3. Automatically record the accumulated flow and accumulated time during the sampling process, and convert the standard volume according to the air pressure and temperature.
The real-time clock can set various sampling methods such as time sampling, interval sampling, multiple sampling, and cyclic sampling.
4. Built-in rechargeable battery for saving data in case of AC power failure. Automatically resume sampling when AC incoming calls, automatically deduct the power-down time during the
sampling process, and allow users to query the power-down time.
5. The imported fan is adopted, with high load capacity and wide flow setting range, which can meet the sampling of large flow. Long-term continuous work with high stability, low noise, more than 20,000 hours of trouble-free operation, long service life, and can work in (-30-50) ℃ environment.
6. The parameters set by the user last time are automatically saved, and the parameters are automatically adopted next time the machine is turned on, realizing one-key sampling. Can store multiple groups
The data is stored for 10 years, which is convenient for users to query.
7. Automatic overload protection: During the sampling process, when the sampling flow rate is less than or greater than the set sampling flow rate, the instrument will automatically
shut down for protection, and power failure protection function: the power failure during the sampling process, the sampling data can be automatically saved, and the sampling will continue after the power is turned on.
8. The user can calibrate the instrument through the waterproof keyboard. Maintenance requires a password to enter, to ensure the security of the instrument data, and
it will not be easily modified and made mistakes, and the function of restoring the factory settings is provided.
9. The unique rain-proof design is suitable for any environment, and the flip-up structure can be folded for easy transportation.
10. The whole machine adopts painted shell structure, anti-corrosion and anti-aging, which is suitable for long-term continuous use in the field.
11. The pull-out type PUF sleeve is adopted, which is easy to operate and easy to install.
