4-in-1 Water Quality Test Meter Set with TDS, PH, EC, and Temperature - Digital Tester with LCD Screen for Swimming Pools and Aquariums - LIAIKI

[Convenient Use] Know your water quality in 5 seconds, accurate and faster. This combo set includes TDS, pH, EC, and temperature readings. It also offers the best price and reliable quality, making it your ideal first water quality test.

[How Accurate is It?] pH resolution is 0.01pH, accuracy ±0.01pH. TDS: 0~9990ppm, Conductivity: 0~9990us/cm, accuracy: ±2%. This is the same high resolution as the top brand on Amazon, but the Pancellent test kit is only half the price.

[Durable Design] The pH pen has an AUTO CALIBRATION function; no screwdriver is needed to calibrate the pH tester pen. The TDS pen has a Lock & Auto shut-off function.

[Pocket Portable] Small size but suitable for testing the pH balance of drinking water, swimming pools, aquariums, reverse osmosis systems, spas, or hydroponic systems.

[Wide Application] Ideal for pH testing at home and in the laboratory, including drinking water, electroplating fluid, boiler water, aquarium water, swimming pool water, photographic rinse fluid, well water, deep groundwater, aquaculture, food processing, and more.

Calibrating the pH Meter

1. Dissolve the calibration powder in 250 ml of distilled or pure water. Immerse the pH electrode in a phosphate buffer solution at pH 6.86 and stir gently.

2. Press the CAL button; automatic calibration will be performed until the displayed value is reached. A standard buffer solution at pH 6.9 is compatible with room temperature.

3. As above, the electrode has been inserted into a standard buffer solution of phosphoric acid, potassium bicarbonate, and phosphoric acid.

4. Leave for approximately two minutes. The displayed value must be within the error tolerance for the pH value of the buffer solution.
