xiamen ZoneWu LoRaWAN water quality COD sensor is a device that can measure the chemical oxygen demand (COD) in water.
xiamen ZoneWu LoRaWAN water Quality High-precision COD Sensor Features:
This COD sensor uses UV method to measure data, without adding chemicals, simple and safe, but also environmentally friendly.
The sensor has an automatic cleaning system, which can clean the dirty things attached to it, without manual cleaning, which is especially stress-free.
It has temperature-transmitting device, which can automatically adjust the result of a measurement according to temperature-changing, no matter how the water temperature changes, it can measure accurately.
It emits modulated light signals, so as to avoid the interference of surrounding visible light, and the data is more reliable.
In addition to measuring COD, it can also measure turbidity. The turbidity data can be used to calibrate the result of a measurement of COD and make the value of COD more accurate.
The LoRaWAN collector can be connected to the LoRaWAN collector through the aviation connector, and then the data is transmitted far away. It can be used in water treatment, fish and shrimp farming, environmental monitoring and other industries, and is simple and convenient to use.

COD Transmitter Size and Installation
1. Submerged installation: The lead wire of the equipment is passed through the waterproof pipe, and the 3/4 thread on the top of the equipment is connected with the 3/4 thread of the waterproof pipe with raw material tape. Make sure that the top of the equipment and the equipment lines are free of water.
2. Pipe Installation: Connect to the pipe through the 3/4 thread of the device.
common knowledge of COD:
What are the specific oxidation conditions for the determination of COD in water samples
COD refers to the amount of oxidant consumed to oxidize reducing substances in 1 liter of water sample under certain conditions, converted into milligrams of oxygen required per liter of water sample after complete oxidation, expressed in mg/L.
How does COD value relate to organic matter content in water
The COD value reflects the degree of pollution caused by reducing substances in water. The larger the COD value, the more severe the pollution in the water. This indicator is also one of the comprehensive indicators of the relative content of organic matter.
What is the relationship between organisms, microorganisms and COD in the water system
High organic content in the circulating water system promotes microbial growth. Therefore, regardless of whether it is for desalination, boiler water or circulating water systems, the lower the COD, the better, but there is no unified limit index. When COD (KMn04 method) is greater than 5mg/L in the circulating cooling water system, the water quality has begun to deteriorate.
How is the chemical oxygen requirements of drinking water determined
In the standards for drinking water, the chemical oxygen demand (COD) of Class | and Class II water is ≤ 15mg/L
Class I water chemical oxygen demand (COD)<20mg/L
Class IV water chemical oxygen demand (COD) ≤ 30mg/L
The chemical oxygen demand (COD) of Class V water is ≤ 40mg/L.
