Compared with other pH meters, the pH is a 3-point calibration method, and our pH is a 5-point calibration method and equipped with a calibration powder (pH 4.00, pH 6.86, pH 9.18, and pH 7.00, pH10.01). You can calibrate effortlessly to ensure the accuracy of your measurements.TDS Meter with Automatic Temperature Compensation Temperature can affect reading levels, digital pH tester has an even better range of 0.0C-60.0C (32.0F-140.0F), automatic temperature compensation can ensure that you are getting the best reading, so you can test with confidence in any environment.High Accuracy Water Tester High-accuracy algorithm chip and electrode of our digital water quality tester ensure an accurate and fast response. Green Backlit LCD Design guarantees that you can read the measuring results in any condition. One-button lock reading function helps lock reading even if the tester is taken out of the sample.pHRange0.00*14.00pHResolution0.01 pHAccuracy0.05 pHECRange0-9990uS/cm; 10.01-19.99 mS/cmResolution1uS/cm, 0.01mS/cmAccuracy2% F.STDSRange0-999ppm, 1000-9990ppmResolution1 ppm. 10ppm.Accuracy2%FS.TempRange0.1-60.0/32.1-140.0Resolution0.1/0.1Accuracy0.5CalibrationPH6.86/4.00/9.18 or 7.00/4.00/10.01EC/TDS1413uS/cm 12.88 mS/cmBLE-9908 Specifications:PH Range: 0.00-14.00Resolution: 0.01phAccuracy: 0.5phEC Range: 0-9999us/cm10.01-19.99mS/cmResolution: 1us/cm, 0.01mS/cmAccuracy: 2% F.S.TDS Range: 0-9999ppmResolution: 1ppmAccuracy: 2% F.S.Temperature Range: 0.1-80.0 32.1-176Resolution: 0.1/0.1Accuracy: 0.5CalibrationpH6.86/4.00/9.18 or 7.00/4.00/10.01EC/TDS1413uS/cm; 12.88 mS/cmATC0.1-60.0Environment0.1-80.0 ; RH: max 90%Battery: 3 * 1.5V(LR44)Not IncludeSize Weight: 187 * 37 * 37mmWaterproof: IP67Packing list:1*4 in 1 ph meter with Bluetooth5* ph buffer power1* manual in English
