Detailed description
Measures conductivity, salinity, resistivity, TDS and temperature. Very wide conductivity measuring range enables measurements in ultra pure water as well as in salines.
Characteristic Features:
- The meter is equipped with a large, easy-to-read backlight LCD with brightness control.
- Enables measurements in ultra pure water as well as saline water.
- The most recent version of this model has been updated and has more additional features which facilitate usage and increase accuracy.
- ”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.
- 6 sub-ranges switched automatically.
- Calibration by entering the constant K of the cell in the range 0.010 ÷ 19.999 cm-1 or in standard solution in 1 to 5 points.
- Ability to store constants K of three cells, which cover the whole conductivity range.
- Wide range of α coefficient chosen depending on the kind of measured solution.
- Possibility of changing the reference temperature.
- Automatic or manual temperature compensation.
- Converting conductivity into salinity, in NaCl or KCl, based on the real characteristics instead of a constant coefficient, what greatly increases the accuracy.
- Possibility to determine the TDS by entering the TDS coefficient in the range 0.2 to 1.0.
- 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 by the EN27888:1999 norm and concern surface water, deep water and well water. This solution lowers the measurement error.
- The measurement accuracy of the ultra pure water with temperature compensation has been improved by automatic adjustment of the α coefficient depending on the kind of trace contamination and temperature.
- Internal clock with date.
- Internal datalogger enables storing up to 4000 measurements taken in series or singly with temperature, time and date.
- Storing the date of next calibration and reminding it, in the right moment, to the user.
- Non-volatile memory of the stored results and calibration data.
- 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.
- IP64 ingress protection.
- Software for data transmission and collection delivered in the set.
The set includes CT2B-121 temperature probe with Pt-1000B resistor and accurate ECF-1 conductivity cell. Range: 0 ÷ 400 mS/cm is sufficient for conductivity measurements in majority of liquids with maximal concentration, ex.: aqueous soil extracts, water with grease, oil or fat. Metal electrodes are easy to clean. Plastic housing protects from mechanical damage.
