Product Summary
The Wireless Conductivity Sensor with Display has an improved range and decreased error when measuring the electrical conductivity of aqueous solutions. Its bright organic light-emitting diode (OLED) display makes data points easy to read for quick spot checks even in bright sunlight. 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. The 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 extending 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.
