HANNA HI84431-01 Total Titratable Low to High Alkalinity Titrator, Electrical: 115V

TOTAL TITRATABLE ACIDITY MEASUREMENT. The HI 84431 by Hanna Instruments® is an automatic titrator designed for easy, fast and accurate analysis of Total Titratable Alkalinity in water. Potentiometric endpoint determination, peristaltic titrant delivery and integrated magnetic stirring systems eliminate the error and technique dependent results associated with manual titrations.The accuracy of the instrument is ensured by performing a peristaltic pump calibration using the provided HANNA standard. The HI 84431 endpoint determination algorithm analyzes the pH vs. volume curve to determine the exact pH endpoint and performs the necessary calculations. The results are displayed in mg/L CaCO3 or meq/L CaCO3 units on the graphic display. An intuitive interface makes the instrument simple to use. A dedicated HELP key guides the user through set-up and calibration sequences, reports instrument status and aids in troubleshooting. HI 84431 features include: log on demand for up to 100 samples (50 pH measurements, 50 titration results), GLP compliance and PC interface via USB. Power: 115V. ((230V model available - See Item #: HAN-HI84431-02). Hanna #: HI84431-01. • • PRINCIPLE OF OPERATION • • The HI 84431 mini automatic titrator determines the total titratable alkalinity in water by potentiometric titration. As titrant is slowly added to the sample solution the pH and temperature are carefully monitored. The software analyzes the resulting pH curve and determines the volume of titrant required to reach the endpoint. Titrations are conducted using the low range reagent (10 to 500 mg/L as CaCO3) or the high range reagent (400 to 4000 mg/L as CaCO3). • Range (pH): -2.0 to 16.0 pH; -2.00 to 16.00 pH • Range (Temperature): -20.0 to 120.0 °C (-4 to 248°F) • Resolution (pH): 0.1 pH; 0.01 pH • Resolution (Temperature): 0.1°C • Accuracy (pH): ±0.01 pH • Accuracy (Temperature): ±0 to 4°C without probe error • pH Electrode HI 1131B (included) • Temperature Probe: HI 7662-M (included) • Pump Volume: 0.5 mL/min • Stirring Speed: 1500 rpm • Environment: 0 to 50°C (32 to 122°F); max 95% RH non-condensing • Power Supply: 115V/60 Hz; 10VA • Dimensions: 208 x 214 x 163 mm (8.2 x 8.4 x 6.4”) (with beaker) • Weight: 2200g (77.6 oz.) Hanna Instruments' HI 84431-01 mini automatic titrator is supplied with HI 1131B pH electrode, HI 7071 filling solution (30 mL), HI 7662-M temperature probe, HI 84431-50 titrant low range (100 mL), HI 84431-51 titrant high range (100 mL), HI 84431-55M pump calibration solution (230 mL), HI 7061 cleaning solution, HI 7004M pH 4.01 buffer solution (230 mL), HI 70083M pH 8.30 buffer solution (230 mL), HI 7010M pH 10.01 buffer solution (230 mL), 100 mL beakers (2), tube set with dispensing tip, Stir bars (medium 2 pcs.), 12 Vdc power adapter, Instruction manual and quick reference guide.
