Direct Reading Ion Meters

Laboratory/Field Direct Reading Ion Meters

Laboratory Ion Selective Electrodes

Simplify your chemical analysis with these direct reading ion meters
  • High Sensitivity: Most ions can be measured to below 1 ppm. Some ions such as copper (+2) can be measured down to the low part per billion range.
  • Fast response time: Ion meters have a rapid response to changing ionic concentration. Response time of 30 seconds to 1 minute is typical.
  • Broad concentration range: Ion meters will detect ions down to the low part per million range up to several thousand ppm. Some of the electrodes will measure up to a concentration of 1 Molar.
  • Resistant Body: The ion meters utilize ion electrodes which usable in acids, bases and some solvents.
  • Portable: The ion meters are fully portable with self contained batteries. On-the-spot field measurements can be made without a trip back to the laboratory.
  • Small Samples: Ion meters can measure samples as small as 5 ml.
  • Quick and Simple Readings: The ion meters are easy to calibrate in the lab or the field. Readings are directly displayed on the meter panel in any convenient concentration units including ppm (parts per million) and Molarity.

Order direct reading ion by checking off the appropriate box below next to the ion meter you want to order.

All ion meters in the table below utilize combination ion electrodes where the reference electrode is already included within the body of the ion selective electrode.
