3.Turn the meter on by pressing “ON/OFF” key.
4.Immerse the pH meter electrode in the solution to be tested (should not be over the immersion line).
5.Stir gently and wait around 30 seconds till the reading stabilizes.
6.After finishing, clear the electrode with pure water, turn the meter off by pressing “ON/OFF” key.
7.Always replace the protective cap after use.
1.Turn on PH meter
2.Disolve each buffer solution in 250ML of distilled water
3.Immerse the electrode into the PH 6.86 solution,(under the temperature of 25)
4.Press the “CAL”(calibration)button for 5 seconds and release
-Display will start flashing 6.86
-Wait until the display stops flashing.
Rinse the electrode with distilled water and dry it with filter paper.
1. Immerse the electrode in PH 4.00 solution,
-Press“CAL”button for 5 seconds, then press and release immediately second time
-Reading will start flashing 4.00
-Wait until display stops flashing
Rinse and dry the electrode with distilled water as before.
6.Place the meter back to the buffer solution to test calibration. If incorrect, please repeat the calibration
7.If approximate PH of your test solution is known to be above 7.0,calibrate the meter using 6.86 and 9.18 solution. To do this, please follow the calibration chart, The third step is the calibration method for 9.18 point.
Product description for TDS
What is TDS?
Total Dissolved Solids(TDS) are the total weight of all solids (minerals, salts or metals) that are dissolved in a given volume of water,expressed in milligrams per liter (mg/L) or in parts per million (PPM).

Data Hold Function: Holds measurement value when moving out of water for convenient reading and recording
Auto-off Function: Shuts off automatically after 10 minutes of non-use to conserve batteries
ATC and Temperature Function: ATC Function promises high accuracy and Temperature Function allows users to get to know the temperature of the the liquid
Come with 1x Poit tds meter, 1x user manual, 2x 1.5V LR44 button cells(build-in); 1x leather carrying case.
