Detailed description
The CP-660 pH meter is a new generation of laboratory measuring instruments. It features excellent accuracy, a 5-inch colour touchscreen, and many additional features that make work easierCharacteristic features:
- May be used to measure pH, mV, redox potential, and temperature.
- Allows simultaneous measurement and display of pH or redox results, as well as temperature.
- 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 ÷ 5 points with possibility of choosing the buffers value in a given range.
- Automatic detection of buffer solutions and standard solutions entered in the meters memory.
- Very helpful during calibration, 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.
- Possibility of storing characteristics of 3 electrodes enables their quick replacement, useful when using different types of electrodes specific for different types of samples.
- Temperature measurement using the CT2S-121 sensor with a selected Pt-1000S resistor – with higher accuracy.
- Automatic control of the electrode’s condition.
- Possibility of viewing the electrode's parameters (buffer and slope).
- Precise redox potential measurement (accuracy ±0.1 mV ±1 digit).
- Automatic or manual temperature compensation.
- Internal clock with date.
- Collecting up to 2000 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 of its exceeding.
- Possibility of choosing the language of the displayed information Polish, 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.
- IP64 ingress protection.
- 24 months of warranty for the meter.
To the device electrodes with a BNC connector can be connected, for example:
EPS-1 for pure water;
IJ-44A for measurements in liquids with sediments and semi-liquid masses;
EPX-4U for re-distilled, ultra pure water;
EPX-4 for chemical compounds;
ERS-2 redox – platinum.
