Industrial Resistivity meter

1 Channel-Panel mount SLIM48

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.



  • Measures ultra pure water at a high degree of accuracy
  • High-precision temperature compensation
  • Freely adjustable standard temperature
  • We make use of a full range of correction equipment
  • Uses lead-free solder
