Industrial resistivity meter
The HE-480R industrial resistivity meter features the high-precision temperature compensation function.
Its high-performance temperature compensation makes it ideal for sequential monitoring of ultra-pure water used in manufacturing processes in the semiconductor field, and many other fields, including the areas of electrical goods, foods and medicines. The measurement range is from 0 to 100.0 MΩ・cm.
