Hot Tap Flange

TRO Chlorine Sensor Direct Pipe Installation

The Hot Tap Flange valve allows our TRO sensor to be installed directly into the Ballast Pipe for fast response and lower installation costs at the shipyard. You will no longer need to use long sample lines, sampling pumps, or sample filtration to get accurate readings.

  • Hot Tap Valve allows removal without draining ballast pipe
  • Fast response
  • Lower installation costs
Explosion Proof

IECEX Version - TRO Sensor

We also offer an Explosion Proof Chlorine Sensor used for Hazardous locations. It has the IECEx Certificate for Group IIC Gases in Zone 1. Our sensor measures total residual oxidant (TRO) and salinity, enabling the chlorine monitor to respond quickly (within 50 seconds). This system includes the use of a sensor with a display located in the Safe Area.

  • Hot Tap Flange Mounting
  • Direct Pipe Insertion
  • Group IIC Gases
  • Zone 1
  • IECEx Certificate
Replaces DPD Systems
