LABORATORY pH / ION METER CPI-502

Zoom

The most important features:

• Measures accurately: pH, redox potential, ion concentration in pX, g/l, M/l, or ppm and temperature (°C).
• The meter is equipped with built-in 60 mm thermal printer.
• The display enables simultaneous readout of the measured function and temperature.
• Calibration of the pH and ION electrodes (ISE) in 1 to 5 points.
• In the pH function automatic correction of the pH standard solution value changes, along with the temperature changes for NIST standards.
• In the ION measurement function molar weight and valence of the measured ion is automatically introduced after choosing the ion.
• Automatic conversion of units – e.g. M/l to mg/l.
• Memory of 4000 results.
• USB output

Detailed description

Characterisctic features:

• Highly accurate measurement in each function.
• Easy parameter setting.
• The meter is equipped with built-in 60 mm thermal printer.
• Standardised procedures for pH and ion selective measurement facilitate working.
• “HOLD” function to freeze the result on the display.
• Signalisation of the result stabilisation with the “READY” symbol and a sound.
• Possibility of sending a calibration report to a PC - up to 10 last calibrations.

In the pH measuring mode:

• Calibration of the pH electrode: 1 ÷ 5 points.
• Automatic pH buffer detection, their value may be set by the user.
• Automatic correction of the stored pH standard value influenced by the temperature change (compliant with NIST), what eliminates the necessity of the temperature adjustment.
• Storage of 3 electrodes calibration parameters enables quick replacement.
• Possibility to view the electrode's characteristics.
• Depending on type of the chosen electrode making measurement in pure water, sewage, pastes, etc. is possible.
• Isolated connectors for pH and ion selective electrode enable their simultaneous connection and measurements in one vessel.
• Automatic evaluation of the electrode condition.
• Readout of the pH electrode condition and data – the zero offset and slope percentage may be checked.

Ion selective measurement

• Enables ion concentration measurements of monovalent, bivalent, negative and positive ions.
• The measuring range enables work with all available ion selective electrodes (ISE), chosen adequately to the kind of measured ion, equipped with BNC-50 connector.
• The meter has separate BNC connectors for the pH electrode, Ion selective electrode and banana connector for the reference electrode.
• The meter automatically introduces the molar weight and valence of a particular ion.
• The user may choose the unit: pX, g/l, M/l, ppm.
• Automatic unit conversion (e.g. mol/l to mg/l).
• Possibility of entering freely chosen values of ion standard solutions.

In the mV and redox potential measurement function:

• Precise redox potential measurement (accuracy 0.1 mV).
• Possibility to measure redox potential relatively to the entered or measured reference potential – Vref.

Other features:

• Automatic and manual temperature compensation.
• Clock with date.
• Internal datalogger for up to 4000 sets of results collected singly or in series with temperature, time and date.
• The readings and calibration data are stored in non-volatile memory.
• Storing of the next calibration date.
• Possibility to connect the meter with a PC by USB output.
• Change of the date protected by a password
• The data transmission software enables printout of the data in a form protected against any changes.
• The meter meets the GLP requirements.
• 24 months of warranty for the meter.
• Pendrive with software for data transmission and collection and user's manual in English included in the set.
