1、 Instrument Description
DS-8000E Portable Water Quality SamplerIt can be used independently with a sampling bucket, or automatically packaged with 12 or 24 bottles of samples. Compliant with the technical requirements and testing methods of the Chinese Ministry of Environmental Protection's water quality automatic sampler (HJ/T372-2007), it has the characteristics of small size, light weight, easy operation, and environmentally friendly energy-saving lamps. Suitable for environmental monitoring stations, supervisory agencies, research institutes, water affairs, municipal and sewage treatment plants at all levels, automatic sampling of water samples from industrial pollution source discharge outlets, rivers, lakes, seas, etc.

IIDS-8000E Portable Water Quality Samplercharacteristic
1. Multiple sampling functions: flow ratio sampling, liquid level ratio sampling, fixed flow quantitative sampling, timed quantitative sampling, excess sample retention, manual sampling, to meet the needs of users.
2. It can be equipped with a high-capacity rechargeable battery pack to ensure that the instrument can work continuously for more than 8 hours, and can be used for both AC and DC.
3. It has flow measurement function for various industrial pollution source discharge outlets in open channels and weirs (with the option of selecting a liquid level transmitter).
4. High reliability peristaltic pump, hybrid stepper motor subdivision drive, smooth and reliable operation, easy to disassemble pump head, pollution-free liquid and pipeline contact, high temperature resistance, and corrosion resistance.
5. The modular program structure, multi CPU control circuit, programmable control, and optoelectronic isolation have improved the overall performance of the product.
6. Liquid flow detector, automatically completes the cleaning and emptying of the sampling port and pipeline, ensuring the collection of qualified water samples.
7. Humanized program design, rich human-machine dialogue interface, large screen digital Chinese LCD display, easy and fast operation.
8. Two level password lock to prevent illegal operations.
9. The whole machine has a small volume, light weight, compact structure, powerful functions, and is convenient for outdoor portable use by users.
