Description

CPC-511 pH/EC Lab Meter + IJ Electrode

Detailed description

Easy in use laboratory measuring device, which measures pH, mV (redox potential), conductivity, salinity, TDS and temperature.

Characteristic features:

• Large LCD enables simultaneous readout of the measured function and temperature.
• Very easy in use.

 

In the pH measuring function

• Calibration in 1 ÷ 3 points in buffer solutions.
• Automatic detection of the pH buffer solution’s value 4.00, 7.00, 9.00 pH (optionally: 4.00; 7.00; 10.00 pH).
• Meter shows information about the pH electrode condition (readout of the buffer and slope values).
• Automatic temperature compensation.
• Depending on the chosen electrode, makes measurement in clean water, sewage, pastes, etc.

 

In the conductivity measuring function

• Measures conductivity in distilled water and other liquids up to 1000 mS/cm.
• 5 sub ranges switched automatically (autorange).
• Salinity measurement converted to NaCl up to 250 g/l or KCl up to 200 g/l.
• Converts conductivity into salinity according to real characteristic and not a constant coefficient.
• Determines estimated value of the total dissolved solids (TDS).
• Calibration, by entering the K constant of the cell or by determining it with use of a standard solution.
• Possibility of entering the reference temperature value.
• Automatic temperature compensation.
• Constant α temperature coefficient 2 %/°C. For precise measurements with temperature compensation it is recommended to use meters with variable coefficient (CPC-502, CPC-505).
• Memory of 50 results.
• Wide temperature measuring range.
• IP64 ingress protection.
• Warranty for the meter: 24 months.

The set includes CT2B-121 temperature probe with Pt-1000B resistor, accurate ECF-1 conductivity cell and EPS-1 pH electrode for measurements in clean water. It should not be used in other types of liquids. Measurements in liquids with sediments should be made with use of IJ-44A pH electrode. Its unusual construction ”intermediate junction” protects the real junction (diaphragma) of the electrode against clogging, ensures stable measurements in these types of liquids or semi-liquid masses, in which other electrodes stop working quickly. When properly handled and maintained the electrode’s lifetime is longer than the standard electrodes.
