FD20 Immersion Fittings for pH/ORP Measuring Loops
Brand: Yokogawa Electric Corporation
The immersion fittings are designed for either pH or ORP (Redox) measurements in tanks, open vessels and drains. They have a "hoisting cable" for easy maintenance.
The program includes fittings for mounting of 1 electrode, 3 electrodes, 4 electrodes or alternatively 3 electrodes and a cleaning system.
As standard, the immersion length can be between 0.5 and 2 m. A flange for fixing in tanks, etc. is available on request.
Features- Designed for either pH or ORP measurements in tanks open vessels and drains.
- Hoisting cable" for easy maintenance.
- Pre-selected immersion length.
- Wide choice of construction materials.
- Flange mounting.
- High degree of standardization reduces spare holding requirements.
- Liquid earth pin for stable measurements.
- Chemical cleaning system as an option.
