RS485 PH ORP Chlorine Analyzer Multi Parameters With 2 Sensors For Swimming Pools
Product Introduction
Free residual chlorine is chlorinated and disinfected in swimming pool water. After a period of contact, there will still be an appropriate amount of chlorine remaining in the water to ensure continuous sterilization. The free residual chlorine in swimming pool water should not be too high or too low. If it is low, it will lose its ability to sterilize. If the chlorine content is too high, it means that too much chlorine will cause certain toxicity to the human body.
DRFN’s PD1000 is a multi-parameter dual-channel controller, which can be connected to a PH/T and an ORP electrode at the same time. Then the instrument will combine the detected redox potential with different PH environments to evaluate the disinfection ability in the water body.
Product Advantages
Applications
The PD1000 dual-channel controller is widely used in swimming pools, water parks, ultrafiltration, circulating water and other occasions that need to quickly evaluate the residual chlorine environment in the water.
