pH EC TDS Meter for Water Hydroponic Nutrient with 8.4oz pH 4.00 Calibration Solution and 8.4oz pH 7.00 Calibration Solution, 4 in 1 pH Conductivity PPM Tester with Simultaneous Display

EZTOCH pH EC TDS Meter for Water Hydroponic Nutrient with 8.4oz pH 4.00 Calibration Solution and 8.4oz pH 7.00 Calibration Solution, 4 in 1 pH Conductivity PPM Tester with Simultaneous Display

• Package: Hydroponic 4 in 1 pH EC TDS Meter with 50ml pH 4.0 and pH 7.0 calibration solution, with 50ml 1413μS/cm calibration solution, 8.4oz (250ml) pH 4.00 Calibration Solution, 8.4oz (250ml) pH 7.00 Calibration Solution, 2*measuring cup 30ml
• Simultaneously display pH EC Temp or pH ppm Temp: This pH tester can display the measured values of pH EC and temperature at the same time. Press the MODE button can adjust to display the measured values of pH PPM and temperature Simultaneously; read 3 parameters at a time, which is easier to use; and this water pH meter has a lock function, whether it is used to measure hydroponics, drinking water or aquarium, you can easily lock and record the readings
• More Accurate pH EC meter: The pH meter has been calibrated before leaving the factory and is ready for use out of the box. Also coming with pH 4.00 pH 7.00, EC 1413μS/cm calibration solution, which can help you confirm whether the pH conductivity tester is in an accurate state at any time. No tedious steps to configure calibration powder are required. It can be calibrated after opening the solution and can be corrected at any time, making pH probe very easy to maintain high accuracy
• pH4.00+7.00 Calibration Solution: large-capacity packaging, suitable for use with all pH meters. The package is equipped with a transparent measuring cup with scale, so that users can accurately grasp the amount of calibration solution (20ml) and better distinguish colors during use, avoiding unnecessary waste and greatly reducing the cost of maintaining the tester. The accuracy of the pH tester calibration solution is up to ±0.02 pH
• Calibration Method: For EZTOCH pH calibration solution 7.00, please follow the steps below: Place the pH probe in the 7.0 calibration solution, press and hold the CAL button for 5 seconds, then release the button and wait for 7.0 to flash 3 times to complete the pH 7.0 calibration. The steps for pH4.0 are the same as those for pH7.0 (Please refer to the manual for the calibration steps of other brands of pH meters
