Apera Instruments SX823-B Portable Multi-Parameter Meter Kit (pH/Conductivity/TDS/Temp.), Accuracy: ±0.01 pH; ±1% F.S

The Apera Instruments SX823-B Portable Multi-Parameter Meter measures pH /conductivity/TDS/temperature simultaneously, with easy display switch among pH (ORP)/Conductivity/TDS (ORP electrode not included). Accuracy: ±0.01 pH; ±1% F.S; ±0.5˚C. Range: -2.00-19.00 pH; Conductivity: 0 to 200 mS/cm (divided into five ranges): (0.00 to 19.99) μS/cm, (20.0 to 199.9) μS/cm, (200 to 1999) μS/cm, (2.00 to 19.99) mS/cm, (20.0 to 199.9) mS/cm; TDS: (0 to 100) g/L.This meter features auto calibration with auto buffer recognition (1-3 points), auto temperature compensation (0-100˚C). High accuracy and consistency, and quick response time thanks to the digital filter technology and auto stable readings recognition (adjustable stable criterion and optional auto-hold function). Plenty of intelligent functions such as indications of completed calibrations, self-Diagnosis of out-of range value and electrode invalidation, auto power-off, easy parameter setup, etc.Reliable structure design: large LCD screen with white backlight, foldable stand allows use as a benchtop meter, soft silicon case gives you a nice grip, IP57 waterproof and dustproof, great for field use. What's in the box: a SX823-B meter, 1 piece of Sanxin 3-in-1 pH Electrode, 1 piece of Sanxin Conductivity Electrode, 4 bottles of calibration solutions (4.00/7.00 pH, 1413μS /12.88mS), connector protection caps, AA backup batteries, a brief operation manual—all in a rugged portable carrying case.The meter is CE certified and comes with a 2-year warranty (6 months for the electrodes). The company designs and manufactures scientific analytical instruments like meters and sensors for pH, conductivity, turbidity, and dissolved oxygen for over 25 years, and meets ISO 9001:2008 Standards. pHRange(0.00 to 14.00) pHResolution0.1/0.01 pHAccuracy±0.01 pH ±1 digitTemperature compensation(0 to 100)˚C (manual or automatic)mVRange±1,000 mVResolution1 mVAccuracy±0.2% F.S ±1 digitConductivityRangeConductivity: 0 to 200 mS/cm (divided into five ranges):(0.00 to 19.99) μS/cm; (20.0 to 199.9) μS/cm;(200 to 1999) μS/cm; (2.00 to 19.99) mS/cm;(20.0 to 199.9) mS/cmTDS: (0 to 100) g/L.Resolution0.01/0.1/1μS/cm 0.01/0.1 mS/cmAccuracy±1.0% F.S ±1digitTemperature compensation(0 to 100)˚C (manual or automatic)Electrode constant0.1 / 1 / 10 cm-1TemperatureRange0 to 100˚CResolution0.1˚CAccuracy±0.5˚C ±1 digitPowerAAA batteries × 3 (1.5V×3)IP ratingIP57Dimension & WeightMeter: (86×196×33) mm / 335 gPortable case:(370×270×77) mm/1.8kg
