Aiperq Electronic pH Meter Tester, 5-in-1 Pool Water Tester with Backlight, pH/TDS/EC/Salinity/Temperature with ATC, High Precision pH Meter with 0.01 Resolution, for Drinking Water, Aquarium, Spas

【Function 5 in 1】 This is a water test kit with PH, TDS meter and EC salinity temperature test function. The backlit LCD monitor facilitates the reading of affixed values

【Easy to use】Put on the power button for the battery. Press "HOLD" to change the value, press for a long time on "HOLD" to change the temperature unit. Select "MODE" to switch between different functions.

【Absolute precision】 The pH resolution is 0.01 pH, precision ± 0.05 pH. Computer resolution TDS 1ppm 0.1ppt, precision ±2%. Conductivity resolution 1uS/cm 0.1mS/CM, precision ±2%. Thermometer resolution 0.1℃/℉, precision ±0.5℃. Salinity resolution 0.01 %, precision 0.01-5.00 %(±0.1 %) 5.10-25.00 %(±1 %)

【Large use】 Idéal for home or laboratory use. Convenient for testing the pH balance of drinking water, swimming pool, aquarium, RO system, spa or hydroponics culture. If the electrode is placed for a long time and the electrode is exposed to the air, the value display is slow and unstable, due to the dryness of the electrode. You must immerse the electrode in the eau pendant for a few hours and re-calibrate the appliance before using it.

Here are four in the containers:

Instructions for use

Caractéristiques:

Automatic étalonnage

Backlit LCD screen

IP67 Étanche

Arrêt automatic

Easy to use

Turn on the value/température switch

Put on the ""ON"" button to reset, tap on the ""HOLD/TEMP"" button to switch the value, and maintain the ""HOLD/TEMP"" button to change the unit temperature.

Use the mode switch

Tap on the button ""ON"" to add, touch ""MODE/CAL"" to switch to other modes.

Rapid and precise measurement of pH meters

1. Before boiling, add the pH4.00/pH6.86/pH9.18 buffered powder into a container containing 250 ml of distilled water and remove just enough so that the powder is completely dissolved.

2. Press the ""ON/OFF"" button to add the pH meter and switch to pH mode

3. Place the electrode in the standard solution pH6.86. and wait until the lecture is established (generally 5 to 10 seconds)

4. Press and maintain the touch MODE/CAL pendant for 6 seconds and relax - just as long as the lecture pH6.86 is no longer known and the heating pH6.86 is over.

5. Repeat the steps below to finish the pH4.00/pH9.18 pH in the order.

REMARQUE: Follow the pH6.86, pH4.00, pH9.18 sequence carefully. Sinon, the results of the étalonnage were inexact.
