Detailed description
CC-461 conductivity meter belongs to the newest generation of electronic devices. It is designed for accurate measurements of: conductivity, salinity, resistivity and temperature.Characteristic features:
- It is distinguished by large colour graphic touch screen.
- The meter may be used for the field measurements as well as during accurate laboratory work.
- Low weight and small size make working in the field easier.
- Waterproof housing (IP-66) enables working in difficult conditions.
- Full measuring range enables measurements in ultra pure water as well as in very salty solutions.
- 6 sub-ranges switched automatically.
- The most recent model has been modified, what results in offering new functions which make working easier, ensure higher accuracy and fulfill more requirements.
- „HOLD” function to freeze the result on the display.
- Signalisation of the result stabilisation with a „READY” symbol and a sound.
- Possibility of sending a calibration report to a PC - up to 10 last calibrations.
- In case of measurements of natural water with conductivity from 60 μS/cm to 1 mS/cm the meter enables using non-linear temperature compensation. The parameters of this type of water are determined in the EN27888:1999 norm and concern surface water, deep water and well water. This function lowers the measurement error.
- The measurement accuracy of the ultra pure water with temperature compensation was increased by automatic adjustment of the α coefficient depending on the kind of trace contaminations and temperature.
- Calibration by entering the constant K in range 0.010 ÷ 20.000 cm-1 or in standard solutions in 1 to 5 points.
- Possibility of changing the reference temperature.
- Possibility to store the constant K of 3 conductivity cells.
- Wide range of α coefficient (0.00 ÷ 10.00 % / °C) chosen depending on the measured solution.
- Automatic calculation of conductivity to salinity in NaCl or KCl on the basis of the real characteristics instead of a constant coefficient, what greatly increases the accuracy.
- Possibility of defining the TDS with entering the TDS coefficient in range 0.2 ÷ 1.0.
- Memory of 3 different temperature sensors parameters. It is possible to enter the group of selected temperature sensor what increases the measurement accuracy.
- The resistivity measurement option added.
Other features:
- Internal clock with date.
- Collecting up to 2000 data sets collected in banks.
- Non-volatile memory of the stored results and calibration data.
- Storing the date of next calibration and reminding it, in the right moment, to the user.
- Possibility of choosing language: Polish, English or German.
- Possibility of connecting with a PC by a micro USB connector
- Powered with rechargeable batteries, or power adapter with USB cable.
- The batteries are charged without taking them out of the meter.
- Continuous work time, without charging, up to 18 hours.
- The meter meets the GLP requirements.
- 24 months of warranty for the meter.
