Pure water conductivity sensor GermanyWTW
I. Introduction to the electrode
Conductivity is an important parameter to measure the electrical conductivity of water. Water can conduct electricity because it contains ions. Truly pure water does not conduct electricity. Therefore, the cleanliness of water can be known by testing the conductivity. By testing the conductivity of sewage, the salt content of sewage can be known. Similarly, the cleanliness of pure water can be known by testing the conductivity of pure water. In addition, conductivity also needs to be monitored in the food and pharmaceutical industries.
（1）LRD 01
Made of stainless steel, for pipeline installation. It has a built - in temperature probe, can withstand high temperatures up to 130℃, and can withstand a pressure of 14 bar. It has 1/2 inch NPT threads. The test range is from 0.01 uS/cm to 200 uS/cm.
（2）LRD 325
For pipeline installation. It has a built - in temperature probe, can withstand temperatures up to 100℃, and can withstand a pressure of 10 bar. It has 1/2 inch NPT threads. The test range is from 1 uS/cm to 2 S/cm.
（3）LR 325/01
For the detection of pure water and boiler water. Made of stainless steel, with a flow channel and a built - in temperature probe. The test range is from 0.001 uS/cm to 300 uS/cm.
（4）LR 325/001
For the detection of ultrapure water. Made of stainless steel, with a flow channel and a built - in temperature probe. The test range is from 0.0001 uS/cm to 30 uS/cm.
