Product Features:

Waterproof level : IP67

Accurate AND Reliable:

reliable Automatic Temperature Compensation (ATC) ensures reading always be accurate at various temperatures.

Just turn PH meter on and stir water gently, then stabilized readings will be showed on LCD in seconds.

Freeze the measurement to view it out of the water. Turns off meter after 5 minutes of non-use to conserve batteries.

Calibration:

Conductivity EC: Supports 3-point calibration automatic identification (1413us 12.88ms and 111.8ms) with 3 calibration points (1413uS/cm 12.88mS/CM 111.8mS/CM)

pH: 1 point (6.86) or 2 points (6.86 4.00) (6.86 9.18) or 3 points (6.86 4.00 9.18) can automatically identify the calibration solution

Pocket Size pH EC TDS Salinity Temperature Meter is the tester for home and laboratory uses. use to test for water, pools, aquariums, spas, hydroponics, food and more.

Note :Pls always clean the electrode every time you run out ; If the pH calibration does not identify the solution, the electrode is broken,thanks!
