Product Name: TDS Meter Digital TDS Water Quality Test TDS Meter Model NO.: WKT-PM Off Mode: Manual Heating Mode: None Operating Mode: Keyboard Chemical Analysis Type: None Physical Analysis Type: Resistivity Method Portable: Portable Application: Agriculture & Food Display: Digital Analysis Method: pH Meter Type: pH Meter Trademark: VICOMETER Transport Package: Carton Origin: China HS Code: 9027809900 Product Description tds meter digital tds water quality test TDS MeterSize6 x 1.2 x 0.6 inches (154 x 30 x 14 mm)Weight1.94oz (55g)Degrees Celsius0.1 - 80.0°CBattery1*3.0V (CR2032) (built-in)MaterialABSFeatures4 Display modes: Press SHIFT button: TDS - ppm & °C, EC - µs/cm & °C, TDS - ppm & °F, EC - µs/cm & °F. 10 minute Auto Shut Off to save battery lifeOperation steps1, remove the protective cover2, first with distilled water pH electrode cleaning, and with the filter paper will be attached to the electrode and the surrounding moisture absorption.3, touch the "key", that is, turn on the power.4, the instrument into the measured solution, so that the measured electrode immersed in solution.5, gently shaking the instrument, to be read after the numerical stability of the figures in the bottom of the display read the value of the solution temperature.6,finished, press the "open key", turn off the power, clean the electrode with water, put on the protective cover.Calibration1, the appropriate amount of 6.86,4.00 and 9.18 standard buffer solution were poured into different clean beakers.2, in order to calibration accuracy, for each buffer solution, with two beakers sub-installed, a beaker to rinse the electrode, the other used to calibrate the beaker. In this way, the standard buffer solution contamination can be reduced to a minimum.3, touch the "switch" button, that is, turn on the power.4, the electrode into the standard buffer solution pH6.86, and gently shake until the display value is stable.5. Press and hold the "Calibration" key (in 6.86 solution) for about five seconds. The instrument will enter the auto calibration mode (the instrument can automatically recognize pH4.00 and pH6.86 standard buffer solution) until the displayed value matches the standard buffer solution. Temperature of the pH value consistent. That is to complete the pH6.86 point calibration.6. Clean the electrode, and use the filter paper will be attached to the electrode and around the moisture absorption, into the pH4.00 standard buffer solution, and gently shake until the display value is stable.7, long press "calibration" key (in 4.00 solution), with the operation of step 5, that is completed pH4.00 point calibration8, clean the electrode and filter paper will be attached to the electrode and the surrounding water to dry, the electrode into the standard buffer solution pH9.18, and gently shake until the display value is stable, the display value within the allowable error range .9, so that the calibration of the instrument is complete.Note: In the following cases, the instrument must be recalibrated.1, after the instrument has been used or placed for a long time;2, the electrode used particularly frequently;3, the measurement accuracy is particularly high;Usually do not press the "calibration key" or the instrument needs to be re-Fourth, the battery replacementIf the displayed value is fuzzy or not displayed, check the battery voltage. If the value is less than 3V, replace the battery in time.Replace the battery, the battery cover can be replaced, pay attention to the polarity of the battery. (Need to recalibrate after replacing the battery)Q1: Why choose Victor Instrument Meter?A: We want to create a superior quality company and to win your trust.Q2: Can I have a sample order for moisture meter?A: Yes, we warmly welcome sample order to test and check quality.Q3: Do you have any MOQ limit for moisture meter order?A: Low MOQ, 1 PC for sample checking is available.Q4: What about the lead time?A: Sample needs 3-5 day, mass production needs about 2-3 weeks for order quantity more than one container.Q5: How do you ship the goods and how long does it take to arrive?A:Airline and sea shipping is optional.
