[MATERIAL]: With plastic cement shell; Light handheld design, portability, and convenience.

[PH METER]: The precision is 0.01; The large screen LCD display is clear, intuitive, and easy to read; The high-quality glass electrode has fast speed, good stability, and higher precision.

[TDS METER]: It can lock data detection; Special temperature compensation function can automatically convert it to TDS value when the water temperature is 25 ℃; Large screen liquid crystal waterproof design, easy to watch and durable.

[APPLICATION]: Ideal for all home and laboratory TDS and pH testing applications, including aquariums and swimming pools.

[CALIBRATION OPERATION]: Mix a packet of 6.86 correction powder with 250ml water and shake gently. Put the pen down to test the pH value of the solution. If it shows 6.8, the pen is accurate; If the display deviates from 6.8, use a small screwdriver to adjust the correction potentiometer (the hole on the back) until the displayed value matches the pH value of the standard buffer solution at ambient temperature. Keep the pen under the water when correcting.

[Attention]: Batteries need to be purchased by yourself.
PH meter: 2 LR44 button batteries;
TDS&EC meter: 1 CR2032 button battery.
