??3-in-1 pH Meter: water quality tester has a three-in-one function, which can measure PH, TDS and temperature with high precision. All-round measurement of water quality to ensure healthy water quality. The water ph meter is an ideal gift for family and friends.

??Due to Recently Reviews about 1413 Solution, please note that TDS Meter had been calibrated by 1413 solution in advance; You can use it directly and it could last for 1 year without second calibration; So 1413 calibraiton solution is not included

??PH Meter for Food with Safety Perforation Design
The Portable tds water tester compact design can be carried around, and the safety perforated design on the top can also save space when hung.

??PH Tester Water with Full Waterproof Design
IP67 Fully waterproof rubber ring design, IP67 waterproof level, each part of the product will have a sealing ring.

??Digital Ph Meter with Built-in Buoyancy
After ph meter for water 0.01 digital ph enters the water, it will immediately rise for easy salvage.

??PH Meter for Water Hydroponics with Ceramic Temperature Electrode-
Extremely fast and accurate measurement of liquid temperature, automatic calculation of temperature compensation.

??[Calibration PH steps of PH Meter Digital Water Quality Tester]:

Step 1: Press the ON on to turn on
Step 2: Press the TEMP / CAL on
Step 3: Adjust to pH mode
Step 4: Place the electrode in the pH 4.00/ 6.86/ 9.18 standard solution
Step 5: Wait for the readings to stabilize(usually 5~10 Seconds)
Step 6: Press and hold the TEMP/CAL on for 6 seconds, then you can see corresponding value flashing 3 times which means calibration of pH is completed.

Tip:

After cleaning the electrode tip (distilled water) and carefully drying the electrode tip (the electrode tip is very fragile).
If the estimated pH value is 9.18, please use 9.

How to make a standard solution to calibrate?
Completely empty the powder into a clean 250ml glass beaker.

Add 250ml of PH Buffer Powder to the beaker.

Still, until the powder has completely dissolved.

PH solution accuracy is ±0.01PH.

Power on→Press the MODEL/CAL on → Adjust to pH mode→Put the electrode into pH4.01 / pH6.86 / pH9.18 standard solution→Press and hold the MODEL/CAL on for several seconds→The value of pH4.01 / pH6.86 / pH9.18 is no lengther flashing, and the calibration of pH4.01 / pH6.86 / pH9.18 is completed.
