GAOTek All-in-one Portable Digital pH Meter Pen and Pocket Tester – High accuracy at 0.1 pH

Description Overview GAOTek All-in-one portable digital pH meter pen and pocket tester is equipped with a standard pH electrode (Circular glass bulb) used to measure the pH of non viscous, non high temperature liquids, e.g., tap water, drinking water, rainwater, etc. This product is equipped with a flat surface pH electrode used to measure the pH of semisolid substances, e.g., fruits, bread, creams, etc. It is equipped with a long reach pH electrode used to measure the liquids in the test tube. The tester is equipped with a standard BNC connector, which can use any pH electrode with BNC plug.   Features High accuracy at 0.1 pH Designed for acid testing applications pH ranges from 0.0 pH to 14.0 pH Calibration at 2 points Equipped with a 6-pin connector Manual hold function for convenience Technical Specifications  pH Range  -2.00 pH to 16.00 pH -2.000 pH to 20.000 pH -2.000 pH to 20.000 pH pH Accuracy  ± 0.01 pH ± 0.002 pH ± 0.002 pH Resolution  0.01 pH, 0.1pH, 0.01 pH, 0.001 pH, Selectable 0.1 pH, 0.01 pH, 0.001 pH, Selectable Calibration Points  2 points 1 point to 5 points 1 point to 5 points Calibration Solutions  USA (4.01 pH or 7.00 pH or 10.01 pH) USA (1.68 pH or 4.01 pH or 7.00 pH or 10.01 pH or 12.45 pH), NIST (1.68 pH or 4.01 pH or 6.86 pH or 9.18 pH or 12.45 pH), DIN (1.09 pH or 4.65 pH or 6.79 pH or 9.23 pH or 12.75 pH) or User defined USA (1.68 pH or 4.01 pH or 7.00 pH or 10.01 pH or 12.45 pH), NIST (1.68 pH or 4.01 pH or 6.86 pH or 9.18 pH or 12.45 pH), DIN (1.09 pH or 4.65 pH or 6.79 pH or 9.23 pH or 12.75 pH) or User defined mV Range  -1999 mV to 1999 mV -1999.9 mV to 1999.9 mV -1999.9 mV to 1999.9 mV mV Accuracy  ± 1 mV ±0.2 mV ± 0.2 mV Resolution  1 mV 0.1 mV, 1 mV, Selectable 0.1 mV, 1 mV, Selectable Calibration Points  1 point (Only for Relative mV mode) Ion Concentration Range  0.001 ppm to 19999 ppm, mg per L, mol per L (Refer to the range of ISE) Ion Concentration Accuracy  ± 0.5 % F.S (Monovalent), ± 1 % F.S (Divalent) Calibration Points  2 points to 5 points (0.001 ppm, 0.01 ppm, 0.1 ppm, 1, 10 ppm, 100 ppm, 1000 ppm, 10000 ppm, mg per L, mol per L) Hold Function  Manual Memory  Stores up to 50 data sets Stores up to 500 data sets Stores up to 500 data sets Output  USB Communication Interface USB Communication Interface Connector  BNC Power Requirements  1 V per 800 mA to 9 V per 800 mA battery 3×1.5 V “AA” batteries (Standard) or DC 5 V power adapter (Optional) 3 V to 1.5 V “AA” batteries (Standard) or DC 5 V power adapter (Optional) Temperature Compensation  32 °F to 212 °F (0 °C to 100 °C) Manual or Automatic 32 °F to 212 °F (0 °C to 100°C) Manual or Automatic 32 °F to 212 °F (0 °C to 100 °C) Manual or Automatic Temperature Range  32 °F to 212 °F (0 °C to 100 °C) 32 °F to 221 °F (0 °C to 105 °C) Temperature Accuracy  ± 1.8 °F (± 1 °C) ± 0.9 °F (± 0.5 °C) Resolution  ± 1.8 °F (± 1 °C) Dimensions 7.28 in x 3.47 in x 1.26 in (18.5 cm x 8.8 cm x 3.2 cm) 6.69 in x 3.35 in x 1.18 in (17 cm x 8.5 cm x 3 cm) Net Weight 10.58 oz (300 g) Grows Weight 4.40 lb (2 kg)
