8500 Conductivity Meter

The 8500 Conductivity Meter is a three-in-one conductivity tester featuring an easy-to-read LCD display that indicates parts per million over a range of 0 to 3500 ppm with a resolution of 1 ppm, millisiemens/cm over a range of 0.00 to 5.00 mS/cm with a resolution of 0.01 mS/cm, and temperature over the range of 0 to 50 °C with a resolution of 0.1 °C.

Both the ppm and mS/cm readings are automatically temperature compensated over the operating range of 0 to 50 °C, utilising the temperature sensor in the probe.

These conductivity meters are housed in a robust ABS case and powered by three AAA batteries that give a minimum of 5000 hours battery life.

The unit will power off automatically after ten minutes, maximising battery life.

At the touch of a button, the instrument will recalibrate itself when used in conjunction with 816-071 calibration solution.

What is the difference between conductivity and TDS meters

In scientific terms, conductivity tells you how well electricity is passing through a substance. On the other hand, TDS indicates the amount of dissolved solids within a liquid, accounting for both conductible and non-conductible particles.

In practice, when measuring conductivity and TDS both conductivity meters and TDS meters pass electricity through a liquid. Conductivity meters can be used to estimate the TDS in a substance.

How do electrical conductivity meters work?

When a probe is inserted into a solution, an electrical current is allowed to flow between the electrodes in the probe. The ion concentration in the solution will affect the current flow which can be measured and read by the meter.
