PHS-3C desktop automatic calibration acidity meter The PHS-3C pH meter is a portable microprocessor-based pH/mV/temperature meter. The handy key board for the selection of the various functions. The possibility of automatically correcting errors in measurement due to temperature and the extreme simplicity of regulation all serve to permit a rapid and reliable execution of calibration and measurement.The display on the front panel reveals the temperature pH or mV readings taken by the instrument. The instrument comes supplied with a combined pH electron and a probe for the measurement and compensation of the temperature. Technical Specification ： 1.Range: PH: 0.00-14.00PH Temp: 0-100℃ 2.Resolution ： РH: 0.01PH Temp: 0.1℃ 3.Accuracy： PH: ±0.02PH Temp: ±0.5℃ 4.Display： PH: 4-digital LED Temp: 3-digital LED 5.Automatic Temperature Compensation:0℃-50℃ 6.Power Supply: In Label 7.Operating Temperature: 0℃-50℃ 8.Calibration: 2 points with auto bufferrecognition Operation： 1.Connecting AC power supply. Turn on the meter by"ON-OEF" switch located back ofthe instrumen 2.Connect the electrode to the iack back of the instrument 3.Remove the protective cap of electrode. Put the electrode into the measured solution to be tested. pH CALIBRATION 1.Pour asmall quantity of pH6.86. pH4.00 and oH9.18 solution into clean beakers. 2.For a particularly accurate calibration, itis advised to use two beakers for each buffer solution; the first is to be used forrinsing the electrode, the second is to be used for the calibration. In this way, the risks of contaminating the buffer solution are reduced to a minimum 3.Switch on the instrument. 4.lmmerse the electrode in a pH6.86 buffer solution, and gently shake it until the reading to stabilize 5.Press the button "CAL" until the calibration Indicator is light.Then press "PH7" until the display shows "6.86". Rinse the electrode with distilled water. 6.lmmerse the electrode in a pH 4.00 buffer solution, and gently shake it until the reading to stabilize 7.Press the button "CAL" until the calibration Indicator is light.Then press "PH4" until the display shows "4,00". Rinse the electrode with distilled water. 8.lmmerse the electrode in a PH9.18 buffer solution. Waiting for the reading to stabilize until the display reading exact 9.18. 9.The calibration of the instrument's pH range is now complete Packing list 1*PHS-3C meter FAQ Q: important A.The instrument's pH range must be re-calibrated whenever: 1.The electrode has been usedlaid for long time from the last calibration. 2.The electrode has been used in particularly taxing conditions. 3.The utmost accuracy is required. 4.Replace the new electrode. yieryi YIERYI brand was registered in 2016. The main products are refractometers, PH meters, tds, ec pens, soil meters, kitchen scales, and jewelry scales. In order to ensure the accuracy of the data, we gave up the low-cost chip, selected high-precision Taiwan imported and South Korea imported chips, the design chose a portable pen-type design, light, beautiful, and easy to carry. All products will be tested, calibrated and used by ourselves to ensure that the quality is qualified and then promoted. We want to let this healthy brand enter every family and every corner of the world, and pass on the dream of "world love, China made"!
