Uses of conductometry

Among many other applications, conductometery could be used for:

• Quality control of distilled and demineralized water
• Conductometric titration
• Determination of the salt content (salinity)

Conductometers

Conductometers with integrated measurement of the temperature

These instruments could be characterized by simple controls and universal usage thanks to wide measuring range, which could be further extended by using conductivity cell with suiltable cell constant.

The instruments are able to resolute up to 0.01 µS on most sensitive range.

	Display	Measuring ranges	Rel. accuracy	Inputs	Supply	Type of the temp. probe
CDT-1	3and1/2 places LCD	20µS/ 200µS/ 2mS/ 20mS	+/- 2%	Temperature, conductivity	Battery 9V	ATC
CDT-2						PT1000

Further features of the CDT-1 and CDT-2

• Three preset conductivities of the standards at 25 °C.
• Indication of the measuring ranges by LEDs.
• Low power consumption.
• Indication of the discharged battery on LCD

Combined and multifunctional instruments

• MPH81 - pH/mV - meter, conductometer and thermometer
• MPH472 - pH/mV/ion meter, conductometer, ammeter (measurement of the dissolved oxygen) and thermometer.

Conductometric cells

The firm Monokrystaly supplies these types of conductometric cells:

Typ	Typical value of the cell constant	Body material	Conductometric range for CDT-1, CDT-2, MPH-81 a MPH472	Integrated temperature sensor
TMS 601	1	plastic	0,01 µS·cm-1 - 20 mS·cm-1	NO
TMS 611	1	plastic	0,01 µS·cm-1 - 20 mS·cm-1	YES
K100	100-150	glass	100 µS·cm-1 - 2000 mS·cm-1	NO

The cells are in standard design, that means they have conductometric vessel. All cells listed have platinum electrodes coated by platinum black.

Application notes on listed cells

• The TMS 6xx cells are primarily intended for general use, like quality control of water, conductometric titration, etc.
• The K100 cell has been developed especially for brewery for testing hydroxide cleaning solutions and for measuring high conductivities.
