Micro Ion Electrodes

After the success of the Lazar micro pH electrode, Lazar Research Laboratories, Inc. developed a series of micro ion electrodes which are used today by research centers worldwide.

Features:
  • 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: Due to membrane design parameters ion selective have a rapid response to changing ionic concentration. Response time of 30 seconds is typical.
  • Broad concentration range: Electrodes 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: Makes electrodes usable in acids, bases and some solvents.
  • Portable: On-the-spot field measurements can be made without a trip back to the laboratory.
  • Small Samples: Measures samples as small as 5 ml. Some of the combination ion electrodes will read down to just 2 ml of liquid.
  • Quick and Simple Readings: The electrodes can be used with any portable or laboratory pH/millivolt meter.
  • Direct Plug: Our electrodes plug directly into your pH/millivolt meter. No compatibility problems.
  • All ion selective electrodes in the table below are combination electrodes where the reference electrode is already included within the body of the ion selective electrode. Mono electrodes without the reference electrode are also available upon request. Please contact us for pricing and delivery.
