TCT-2531 PeakOFT

TCT-2531 PeakOFT

Optical transmission sensor

The TCT-2531 PeakOFT measures total consistency in waste water applications of paper mills in the range of 0% to 0.8%. With its open flow through sensor it is designed for installations in open channels or in a pressurized line.

  • Measures consistency or total suspended solids
  • Optimize chemical additives
  • Improve water treatment process
  • One point measurement allows installation flexibility and simple handling
  • Optical sensor without moving parts providing low costs of operation
