Halogen Systems TRO Chlorine Sensor for Ballast Water Management Systems - Certifications and Approvals - DNV-GL - IECEx - Korean Register - US Coast Guard

On-Line Sensors For Seawater, Brackish Water & Freshwater Applications

Some ports have much higher amounts of suspended solids and the water can even appear \”muddy.\” Additionally, when ballast tanks are emptied, silt remaining in the bottom of the tank has a similar effect. Our sensor still performs 40 times the required TSS level.  Other traditional DPD methods would be adversely impacted resulting in inaccurate readings. Learn more here or simply contact us.

Our TRO Sensor Receives DNV GL Type-Approval

Recently Halogen Systems Inc has gained more recognition and significant approvals on its Amperometric DPI (direct pipe insertion) TRO (total residual oxidant) sensor. They have just been awarded DNV GL type-approval on their ballast water management system (BWMS) sensor that measures TRO in ballast water for applications of 0.2 PSU salinity and higher. President of Halogen Systems, Michael Silveri, relays: “There is now a low maintenance alternative to DPD instruments

DNV Evaluation Report on Halogen Systems Amperometric TRO Sensors

DNV Evaluation Report on Halogen Systems Amperometric TRO Sensors This just in… It is DNV GL’s opinion that the testing performed by HSI demonstrated that the amperometric TRO sensor by HSI may be applied by BWTS for measuring the TRO of the treated ballast water both during ballasting and deballasting operations. The HSI TRO sensor offers comparable performance to the online DPD-based TRO sensors currently applied by BWTS. You’ll find

Streams Of Information

Streams of Information – Ballast Water TRO A small company develops a breakthrough sensor used in ships’ ballast-water treatment systems After developing chlorine and bromine generators for swimming pools in the late 1980s, Michael Silveri launched a small company in 1994 that created sensors for hot tubs and pools. His early modest success hardly foreshadowed his next undertaking: devising cutting-edge technology for a water-treatment sensor for ballast water maintenance systems. See
