Product Details

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.

- 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)

Battery Type Coin Cell

1 Minimum # of data points with all measurements enabled, actual results depend on enabled measurements.

2 Continuous use in a connected state until battery failure, actual results will depend on sample rate, active measurements, and battery condition.

3 Logging until battery failure, actual results will depend on sample rate, active measurements, and battery condition.

* Normal classroom use is the sensor in active use for 20min/lab for 120 lab periods/yr.
