pH / ION METER CPI-601

Zoom

The most important features

• Very high accuracy meter for laboratory use.
• Measures: pH, redox potential, ion concentration in pX, g/l, M/l, or ppm and temperature.
• All the results are simultaneously displayed on a 7” graphical colour touch screen.
• Calibration in 1 to 5 points.
• The meter has separate BNC connectors for the pH electrode and the ion selective (or redox) electrode, and a banana connector for the reference electrode.
• In the pH function, automatic correction of the pH standard value with temperature (NIST standards).
• In the ION measurement function, molar weight and valence of the measured ion are automatically entered after choosing the ion.
• Automatic conversion of units – e.g. M/l to mg/l.
• Memory of 2000 data sets.
• USB output.
• Meets the GLP requirements.

Detailed description

Characteristic features:

• Programming of the parameters is very easy.
• Unification of operating procedures for all functions makes working easier.
• “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 function:

• pH electrode calibration in 1 to 5 points.
• Automatic detection of pH buffer and standard values entered by the user.
• When NIST pH standards are used, their stored values are automatically corrected for temperature, so there is no need to heat or cool the solutions.
• Storing the characteristics of 3 pH electrodes enables their quick replacement.
• Automatic control of the electrode’s condition.
• Readout of the pH electrode parameters – zero offset and slope.
• Depending on the electrode used, measurements in pure water, sewage, pastes, etc. are possible.
• The measuring circuits of the pH and ion connectors are isolated, which enables accurate, error-free simultaneous measurements in the same vessel.

In the ion selective measuring function:

• 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 automatically introduces the molar weight and valence of a particular ion.
• The user may choose the unit: pX, g/l, M/l, ppm.
• Automatic conversion of units – e.g. M/l to mg/l.
• Possibility of entering freely chosen values of ion standard solutions.
• The meter has separate BNC connectors for the pH electrode and the ion selective (or redox) electrode, and a banana connector for the reference electrode.

In the redox (mV) measuring function:

• Precise redox potential measurement (accuracy 0.1 mV).
• The mV measurement is possible using the pH or the ISE connector.
• Possibility to measure redox potential relatively to the entered or measured reference potential – Vref.

In the temperature measuring function:

• Choice of the unit: °C, °F, K.
• Entering the group number of the selected temperature sensor, which increases the accuracy.

Other features:

• Automatic or manual temperature compensation.
• Internal clock with date.
• Datalogger for 2000 data sets of all currently measured functions.
• Storing of measurement results with time and date, taken singly or in series at a set time interval.
• The results and calibration data are stored in non-volatile memory.
• Possibility of screen brightness control depending on the external conditions.
• Storing of the next calibration date.
• USB output to connect with a PC.
• Possibility to choose English or German language.
• IP64 ingress protection.
• The meter meets the GLP requirements.
• 24 months of warranty for the meter.
