1. Product overview

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

2. Product Features

1. Adopt imported wide -temperature OLED display screen, good man-machine interface with Chinese menu and pictures and texts, eliminating the need for adjustment and comparison

It can work in ultra-low temperature environment.

2. The flow control adopts high-precision imported sensors, with good flow stability, high sampling accuracy, and automatic detection and sampling

Flow, automatically control constant current sampling to compensate for flow fluctuations caused by voltage and resistance changes.

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 when the AC power is off

The power-down time during the sample process, and can be used by 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

High operating stability , low noise, trouble-free running time of more than 20,000 hours, long service life, can be in (-30-50) ℃

work in the environment.

6. Automatically save the parameters set by the last user, and use it automatically the 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 is less than or greater than the set sampling flow, the instrument automatically stops.

Machine protection, power failure protection function: 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.

It will be easily modified to make mistakes, and provide the function of restoring factory settings.

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.
