SURAT CHEMICAL TAG:
TRO Calibration Solution kit is a calibration solution compatible and to be use with HF Scientific TRO Analyser. Compatible HF TRO Analyser include CLX-EX, CLX-EX2, CLX-XT, CLX-XT2 TRO Calibration Solution Kit is an essential calibration package for the operation of chlorination/oxidation type of ballast water management system. TRO sensor which is calibrated, ensure the right amount of chlorine/oxidant is injected for disinfection of ballast water and excess chlorine/oxidant is neutralised for compliance.
Technical Highlights
- Measurement Range: Instrument-dependent
- Method Type: Colorimetric (DPD)
- Compatibility: TRO analyzers, portable chlorine meters, and laboratory photometers
- Reagent Form: Liquid (Buffer & Indicator), Powder (DPD Sachets)
Principle Method of RXSOL TRO Kit
The kit uses the internationally recognized N,N-Diethyl-p-phenylenediamine colorimetric method.
When DPD powder is added to a water sample containing total chlorine or oxidants, a pink/red coloration develops. The intensity of the color is proportional to the oxidant concentration and is measured visually or using a photometer to determine TRO/total chlorine levels.
How to use TRO Calibration Kit?
Follow guidelines given by TRO Monitor/Sensor manufacturer.
