Features
The unique design makes this products compared to similar products with lower failure rate, lower maintenance, lower reagent consumption and higher cost.
Injection components: vacuum suction peristaltic pump, and the pump tube between the reagent there is always an air buffer, to avoid corrosion of the tubing, while making reagent mixing more concise and flexible.
Sealed Digestion components: high -temperature high-pressure digestion system, accelerating the reaction process, to overcome the volatile corrosive gas exposure system equipment corrosion.
Reagent tube: imported transparent modified PTFE hose, diameter greater than 1.5mm, reducing the chance of water-like particles clogging.Application
1. Environmental sampling inspection in large watershed.
2. Used by laboratory researchers.
3. Fishery aquaculture environmental monitoring.
4. Monitoring of sewage outlets in sewage plants.
5. Rivers, lakes, creeks, etc. Installation and production environment
