HE-480R
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.
ADVANTAGE
- 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
