【How to Calibrate】With 4.01/6.86/9.18 ph buffer powder and ORP buffer powder (Not all three packs of calibration powder need to be calibrated, according to the actual situation, one powder bag can also be calibrated). Prepare three cups of 250ML water and pour in the buffer powder. Step 1: Turn on the power supply of the ph meter. Step 2: Press the MODE and CAL button. Press the MODE and CAL button for about 6 seconds, and the ph meter flashes three times to complete the calibration.
【8-in-1 pH Meter】ph meter for water has a 8-in-1 function, which can measure PH, TDS, Temp, EC, Salinity,ORP,S.G,H2 with high precision at the same time. All-round measurement of water quality to ensure healthy water quality. The detailed manual included will show you how to get the best accurate and stable reading.
【High Accuracy Digital pH Meter】PH measurement 0-14, TDS 0-200000ppm,EC 0-200000㎲/cm,Salinity 0-20%,ORP ±1999MV,H2 0-2400PPb,S.G 1.000-1.222,temperature 0-60℃. Backlit LCD Design guarantees that you can read the measuring results in any condition. One-button lock reading function helps lock reading.
【The Importance of Water Quality】 The water is too acidic or too alkaline, which has adverse effects on human body. TDS water quality detection pen can help us to detect the composition of drinking water at home at any time. Water quality is closely related to health, and good water quality can delay aging. 8-in-1 PH water quality testing pen is a household necessity.
【Widely Used】 pH/TDS meter ideal for home or laboratory uses. Water ph tester can be used to test drinking water, swimming pools, pH balance in aquarium, bath tub, spa, wine, beer and any other liquids, pH pen make you get the quality of water at any time and get accurate data.

Calibration pH Steps
 
  • Before calibration, add the pH4.00/pH6.86/pH9.18 buffer powder into beaker with 250ml (under the temperature of 25℃) of distilled water, then stir until the powder has completely dissolved.
  • Press the ON/OFF button to turn on.
  • Press the TEMP / CAL button, adjust to pH mode.
  • Place the electrode in the pH pH4.00/pH6.86/pH9.18standard solution. 5. Wait for the readings to stabilize(usually 5~10 Seconds).
  • Press and hold the TEMP/CAL button for 6 seconds, then you can see corresponding value flashing 3 times which means calibration of pH is completed.
Package Includes
 
  • 1 x pH Meter
  • 4 x pH buffer powder
  • 1 x User's manual

5 in 1

  • 5 in 1 Water Quality Tester: PH, salinity, temperature measurement, TDS, EC meter five-in-one. TDS measurement range: 0-200000ppm; EC measurement range: 0-200000US/cm; PH measurement range: 0.01-14.00pH; salt water meter measurement range: 0.00-25.00%; temperature conversion function.
  • Two Salinometers: The digital pH meter can detect the salinity of table salt; at the same time it can detect the salinity of seawater. Food salinity measurement range: 0.00-25.00%; seawater salinity measurement range: 10.1-200.0ppt. The TDS and salinity units are the same, but when measuring salinity, the pH meter needs to be converted to salinity mode.
  • High Precision: The high-precision algorithm chip and electrodes of our detector ensure an accurate and fast response. When the measured value is stable, just press the HOLD/TEMP button to lock the measured value and take it out for viewing, which is very simple.
  • Auto Power Off and Large Display: The tester has a backlit LCD to help you see your measurements clearly in any situation. The Auto Power Off feature turns off the power after 5 minutes of inactivity to save power. A fully transparent liquid crystal (LCD) is used to display the 4-digit value and the corresponding physical quantity unit.
  • Automatic Temperature Compensation:: Temperature may affect reading levels, digital hydroponics pH meter has a range of 0°C-60°C (-0-140°F), automatic temperature compensation ensures you get the best readings, so you can rest assured Test in any environment.
  • Wide Range of Applications: The detector has a variety of uses. The instrument can not only detect the salt content of edible salt, saltwater pools, and fish ponds but also detect the salinity of seawater and saltwater fish tanks, and test the pH value of drinking water, swimming pools, aquariums, etc.

Package Included

  • 1 x 5-in-1 Detector
  • 3 x pH buffer powder
Notes
  • Clean the electrode with distilled water Every time before and after use, gently wipe it with a clean, soft cloth when you're done before capping it again.
  • Be sure to add water according to the required ratio, otherwise it will affect the accuracy of the calibration and increase the error.
Notes
  • Due to different batches, there may be errors in the product appearance and color. Please refer to the actual product received!
