HE-480R

Panel-mount type resistivity meter (resistivity meter)

UPW (ultra-pure water) monitoring for the semiconductor, electronics, food, and pharmaceutical industries.

A resistivity meter with high-precision temperature compensation performance. Ideal for continuous monitoring of ultra-pure water used in various fields such as semiconductor, electronics, food, and pharmaceutical manufacturing.

Division: Process Water
Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

Highly responsive temperature sensor

Helps to minimize fluctuations in measurement values due to delayed temperature compensation in the event of sudden changes in water temperature.
