HO-480

패널 장착형 ORP 미터 (4-Wire Transmission)

산업용 ORP meter는 모든 종류의 용매의 산화-환원 전위를 측정하기 위한 ORP 변환기입니다.
무연 센서와 결합하여 환경 친화적인 측정이 가능합니다.

- 측정 범위 : 0 ~ ±2000 mV

Segment: Process And Environmental

Division: Process Water

Manufacturing Company: HORIBA Advanced Techno Co., Ltd.

Includes a sensitivity correction function
It is possible to compensate for changes in the sensitivity of the ORP electrodes.
A line-up of lead-free ORP electrodes
Not only the glass body, but almost all sections of the ORP electrodes, including lead wires and soldered junctions are lead free.
Uses lead-free solder
To reduce the burden on the environment, lead-free solder has been used to mount the components on the printed circuit board.
