Brief introduction
In order to meet the demand for turbidity separation of water samples during on-site sampling, The KD-700 portable water quality centrifuge is developed according to the requirements of the China Environmental Monitoring Station, and meets the file parameter requirements for pre-treatment of surface water total phosphorus monitoring site in Appendix A of the "HJ91.2-2022 Technical Specification for Surface Water Environmental Quality Monitoring" (speed ≥ 2000r/min, set centrifugation time ≥ 1min, single centrifugation water sample ≥ 1L). The speed setting range is (200-2100) rpm. There are three indicators for turbidity in non tidal river sections (less than 200, 200-500, and greater than 500). When the turbidity of the water is greater than 500, a centrifuge is needed to centrifuge the water sample; There are two indicators of turbidity in tidal river sections (less than 200 and greater than 200), and a centrifuge is needed to centrifuge the water sample when the turbidity of the water is greater than 200.
2、 Execution standards
HJ91.2-2022 Technical Specification for Surface Water Environmental Quality Monitoring
3、 Application scope
On site monitoring of total phosphorus in manual monitoring of surface water (rivers, lakes, reservoirs, etc.) environmental quality.
4、 Technical features
Equipped with a large capacity lithium battery, there is no need for a dedicated power supply, making it easy to operate on site.
Easy to operate, one click operation, maintenance free.
Unique frame style cavity design, with a solid and reliable overall structure.
The centrifugal chamber and the cover air duct form a circulating air duct system, which maintains excellent heat dissipation for the entire chamber, motor and other components, improving the stability and high reliability of the whole machine.
The spindle adopts high-precision imported bearing design, with high reliability and good stability.
The shell is made of metal material, which is resistant to vibration, collision, and has good sound insulation and heat insulation effects.
Adopting double-layer shock absorption and noise reduction technology and a special high-efficiency power system, the entire system runs smoothly and reliably.
