Product Summary
The Wireless Conductivity Sensor has an improved range and decreased error when measuring the electrical conductivity of aqueous solutions. It is ideal for investigating the ionic properties of solutions, including calculations for total dissolved solids (TDS) often used for water quality inquiry. Temperature compensation handles calibrations across a range of temperatures. New design supports a doubling of previous conductivity determination, now up to 40,000 µS/cm, this sensor can be utilized for chemical, biological, and environmental studies easily into brackish waters.
Teacher tip: To measure fully marine samples above sensor range, dilute your salt water solution in half then multiply sample conductivity x 2.
Features
- Measure conductivity and total dissolved solids
- Automatic temperature compensation
- Battery life >1 year
- Remote logging with built-in memory
- Dust-proof, sand-proof, and water-resistant (1 meter for 30 minutes)
Applications
- Water quality investigations
- Performing condumetric titrations
- Investigating solution properties
- Diffusion of ions through membranes
- Differences between ionic and molecular compounds
- Comparing strong and weak acids
How It Works
Conductance is the reciprocal of resistance. In this case, the Wireless Conductivity Sensor measures the current flowing through the circuit when submerged in solution and voltage is applied. The electrode cell is constructed from insulating material with two pins made of 300 series stainless steel placed a fixed distance apart to serve as the sensing element. The Wireless Conductivity Sensor includes built-in temperature compensation to extend the useful range an minimize the need for calibration.
