Horiba Cardy Potassium Ion Meter Replacement Sensor

This is the replacement sensor for the Horiba Cardy Potassium Ion Meter.

Main Uses:

  • Measuring leaf sap,
  • Measuring soil potassium levels,
  • Measuring foliar and hydroponic fertilizers.
  • Measuring concentrations in animal bodily fluids.
  • Measuring fruit juices and milk
  • Using the sample sheets as a swab, soaked in distilled water and wiping over a hard surface to measure surface potassium levels.
Main Features

The measurement process simply involves placing the sample on the meter's flat sensor. Accurate measurements can be taken from samples as small as 0.1ml.

Automatic range switching gives a wide display range and facilitates highly precise measurements.

The meter employs a highly selective flat ion electrode. As it is unreceptive to other ions, the electrode takes highly accurate measurements of nitric acid ion concentrations. The new high molecular weight polymers are longer lasting and more resistant to contamination, giving you more troublefree service and saving money on replacements.

Ultrathin and lightweight, the meter can be easily carried to any location for on-site testing.
