“Expert-pH” is a fundamentally new generation pH meter with automatic control of the temperature effect during calibration and “intelligent” automatic temperature compensation.

pH meter “Expert-rn” – extremely easy to use.

Convenient ergonomic design and optimal dimensions of the “Expert-rn” pH meter allow you to measure not only in the laboratory, but also in the field or in production.

Appointment of the pH meter “Expert-rn”:

– measurement of pH, Eh, EMF, temperature

– determination of acidity and alkalinity of various objects


What distinguishes “Expert-rn” from just a pH meter? pH meter “Expert-rn” is:

1. Automatic control of temperature influence during calibration.
The memory of the pH-meter “Expert-pH” stores tables of dependence of pH of all basic buffer solutions on temperature. When calibrating, the pH meter measures the temperature of the solution and automatically corrects the pH value for maximum accuracy. Thus, calibration of the pH meter can be performed without a thermostat at any temperature.

2. “Intelligent” automatic temperature compensation.
pH meter “Expert-rn” controls the temperature of the analyzed solution, compares it with the calibration temperature and independently selects the optimal measurement mode – with or without temperature compensation. The operation algorithm of the pH meter provides for automatic adjustment of the isopotential point of the electrode and its real sensitivity. This “intelligent” system guarantees correct results at any temperature.

3. Simple, intuitive user menu.

4. Signaling when readings stabilize

5. Indication of prompts and messages in case of errors

6. Warranty for the “Expert-rn” pH meter – 30 months*
*warranty for sensors – in accordance with the passports

7. measurements according to PND F 14.1:2:3:4.121-97 (ed. 2004) GOST 26483-85 GOST 26212–91 GOST GOST 26423-85 PNDF 16.2.2:2.3:3.33-02 GOST 27753.3-88 GOST 27979-88 GOST 29207-91 GOST 24596.5-81 GOST 24024.5-80 GOST 26180 – 84 GOST R 51478-99 GOST 26781-85 GOST 28972-91 GOST 26188-84 GOST 30648.5-98-6 GOST 938. 25699.6-90 GOST 21119.3-91 GOST 27403-87 GOST R 50029-92 GOST 12523-77 GOST 29188.2-91 etc.
