Total Titratable Acidity System Including pH and Temperature monitoring (HI 84430-01)

hi_84430_sm.jpgThe HI 84430 is an automatic titrator designed for water analysis that is easy, fast andaccurate. Potentiometricendpointdetermination, peristaltic titrant delivery and integrated magneticstirring systems eliminate the error and technique dependent resultsassociatedwith manual titrations.

The accuracy of the instrument is ensured by performing aperistaltic pump calibration using the provided HANNA standard. The HI84430 endpointdetermination algorithm analyzes the pH vs. volume curve to determinethe exact pH endpoint and performs the necessary calculations. Theresultsare displayed in mg/L CaCO3 or meq/L CaCO3 units on the graphic display.

titration_1.jpgAn intuitive interface makes the instrument simple to use. Adedicated HELP key guides the user through set-up and calibrationsequences, reportsinstrument status and aids in troubleshooting.

This titration method is not subject to the same interferences as a colormetric technique and the peristaltic pump assure the best performance and repeatability possible.

titration_2.jpgHI 84430 features include: log on demand for up to 100 samples (50pH measurements, 50 titration results), GLP compliance and PC interfacevia USB to use with the HI92000 windows software (Sold Seperately).

Titrations are conductedusing the low range reagent (15 to 500 mg/L as CaCO3) or the high rangereagent (400 to 4000 mg/L as CaCO3).
