With AD 11 tester the pH and temperature of the water can be easily and precisely measured. No reagent is required to measure the pH value. It must be calibrated periodically. The product package includes accessories for calibration and storage.

PROPERTIES:

Waterproof, the house fully protects against moisture. pH measurements are done by automatic temperature compensation (ATC) and temperature values ​​can be displayed in ° C or ° F units. 

Can be calibrated to one or two-point pH with automatic buffer recognition for 5 inputs buffer.
Recommended for calibration: - Buffer solution pH 4 (50 ml / bottle) - Buffer solution pH 7 (50 ml / glass)

The measurements are very accurate thanks to the unique stability display on the right of the LCD. Models warn the user if battery replacement becomes necessary. The electrode supplied with the meter can easily be exchanged by the user. (See the battery electrode by clicking here.) The encapsulated temperature sensor enables fast and accurate temperature measurement and compensation.

Contents of the package:

• 1 x AD11 tester box (with calibration fluid, .4x1,5V button element, Hungarian manual)
• 1 pH buffer solution no.4, 50 ml
• 1 pH buffer solution no. 7, 50 ml
• 1 KCl storage fluid, 30 ml
• 3 beakers (2 for calibration, 1 for water rinsing electrode)

Do not allow the electrode to dry out as it leads to probe aging and inaccuracy.

Do NOT use deionised water for storage!
