Yra trys skalės: 0..200 μS, 0..2000 μS, 0..20000 μS. Conductivity sensor The CMA Conductivity sensor BT27i can be used to measure the conductivity of a solution. It has three measurement ranges, which can be selected using a switch located on the side of the sensor box:
• 0 to 200 µS
• 0 to 2000 µS
• 0 to 20000 µS.
The Conductivity sensor consists of a conductivity electrode and an amplifier. The conductivity electrode is a simple ABS-bodied 2-cell graphite type. It can be used for measuring salinity and changes in conductivity of a water sample. Although it will not identify the specific ions that are present, it can be used to determine the total concentration of ions in a sample.

The Conductivity sensor can be used to perform a wide variety of experiments:
• Confirmation of the direct relation between conductivity and ion concentration in aqueous solutions. Concentration of unknown samples can be determined.
• Measurement of changes in conductivity resulting from photosynthesis in aquatic plants, with the resulting decrease in bicarbonate-ion concentration due to the carbon dioxide consumption.
• Monitoring the rate of reaction in a chemical reaction in which dissolved ions and solution conductivity varies with time due to ionic species being consumed or produced.
• Performing a conductivity titration to determine when stoichiometric quantities of two substances have been combined.
• Finding the rate at which ionic species diffuse through a membrane such as dialysis tubing.
• Monitoring changes in conductivity or total dissolved solids in an aquarium containing aquatic plants and animals. These changes could be due to photosynthesis or respiration.

The Conductivity sensor can be directly connected to analog BT inputs of the CMA interfaces.
Attention: The sensor cable BT - IEEE1394 needed to connect the sensor to an interface is not supplied with the sensor and has to be purchased separately (CMA Art. Nr BTsc_1).

Technical specifications of the sensor are described in its User's guide.
