The most important features

• pH meter for use in laboratory.
• Measures pH, redox potential (ORP) and temperature.
• Simultaneous observation of all the chosen functions results on the colour touch sreen.
• Calibration in 1 to 3 points.
• In the pH function automatic correction of the pH standard solution value changes, along with the temperature changes for NIST standards.
• Memory of 500 data sets.
• USB output.
• Small size and weight.
• The meter meets the GLP requirements.

Detailed description

Characteristic features:

• Depending on the kind of applied electrode it may be used for clean water, sewage, soil, pastes, meat, cheese and other measurements.
• Calibration of the pH electrode in 1 ÷ 3 points with possibility of choosing the buffers value in a given range.
• Range of the entered calibration points:
  1 point 0.000 ÷ 6.000 pH,
  2 point 6.800 ÷ 7.100 pH,
  3 point 8.000 ÷ 14.000 pH.
• Automatic detection of buffer solutions and standard solutions entered in the meters memory.
• Automatic correction of the pH standard solution value along with the temperature changes for NIST standards, what eliminates the necessity of the standard solution temperature adjustment.
• The NIST standard solutions entered in the meters memory are phtalate, phosphate and borax or bicarbonate (chosen when the meter is ordered). The solutions in 20°C have following values: 4.001 pH, 6.881 pH, 9.225 pH or 10.064 pH.
• Possibility of storing characteristics of 3 electrodes enables their quick replacement, useful when using different types of electrodes specific for different types of samples.
• Automatic control of the electrode’s condition.
• Possibility of viewing the electrode's parameters (buffer and slope).
• Precise redox potential measurement (accuracy 0.1mV).
• The pH and conductivity measurement circuits are isolated, so there is no interference during simultaneous measurements.
• Automatic or manual temperature compensation.

Other features:

• Internal clock with date.
• Collecting up to 500 data sets in the internal data-logger with temperature, time and date, single collecting and taking series of measurements of all measured functions.
• Non-volatile memory of the stored results and calibration data.
• HOLD function to freeze the actual measurements results on the screen.
• Stabilised reading signalisation.
• Storing the calibration validity date and signalising it to the user.
• Possibility of choosing the language of the displayed information : English, German, French, Italian, Spanish, Portuguese.
• Possibility of connecting with a PC by a USB connector.
• Software for data transmission and collection delivered in set.
• Up to 10 last Calibration Reports transfer to a PC for printout.
• Powered with 5V/1000mA USB power adapter.
• The meter meets the GLP requirements.
• 24 months of warranty for the meter
