Detailed description

Characteristic features:

• Wide measuring range enables measurements in ultra pure water as well as in high conductivity solutions.
• 6 sub-ranges switched automatically.
• The first sub range 0 to 20 μS/cm enables measurements of pure water with resolution up to the 3rd decimal place.
• 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 norm EN27888:1999 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 temperature α coefficient depending on the temperature and kind of trace contaminations.
• The reference temperature may be chosen between 25°C and 20°C.
• Calibration by entering the constant K in range 0.010 ÷ 20.000 cm^-1 or in standard solutions in 1 to 3 points.
• Wide range of α coefficient 0 ÷ 10 % / °C chosen depending on the measured solution.
• Automatic calculation of conductivity into 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.
• Resistivity measurement function.
• Memory of 3 conductivity cells constant K values enables fast replacing in case of measurements in different ranges.

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 a 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.
