Portable Multi-Parameter Water Quality Meter – DO, PH, ORP, Conductivity, Turbidity, NH₃-N, With Auto-Clean

1.Product Introduction

The KNF-1505 portable multi-parameter water quality detector adopts an integrated design, integrating water quality monitoring sensors such as dissolved oxygen, pH, ORP, conductivity/salinity, turbidity, temperature, ammonia nitrogen, and nitrite. It can be equipped with up to six sensors and is equipped with an automatic cleaning device, effectively reducing the product maintenance cycle and improving the stability and accuracy of product measurement. Reliable and easy to use, it is convenient to install. The main unit of the detector is powered by a large-capacity lithium battery and has built-in storage and data export functions. It is suitable for online water quality monitoring in environmental protection monitoring, water supply and drainage, ecological environment and other fields. The multi-parameter water quality sensor is equipped with an automatic cleaning device, which can set the automatic cleaning interval time and the number of automatic cleaning cycles to adapt to water of different cleanliness levels. The automatic cleaning device can effectively clean the surface of the sensor, prevent the adhesion of microorganisms, and greatly reduce maintenance costs. Each sensor is equipped with a quick-plug waterproof connector for easy disassembly and assembly.

The sensor protective cover at the front end is used to protect the internal sensors from damage. There are slots and holes around the protective cover, which can effectively prevent large suspended particles and organisms from damaging the sensor probe, while not affecting the measurement accuracy.
