Ion meters are specially designed for the detection of particular ion concentrations in a solution. Yatherm Ion meter manufactured with detection of multi Ions (Fluoride, Calcium, Sodium, Chloride & Nitrate), Ph, ORP & Water hardness with a 7-inch TFT display. Yatherm Scientific offers Multi parametric Ion Concentration Meters when used with particular ion-selective electrodes and corresponding reference electrodes can measure the correspondent electrode potential MV value, PX value, and ion concentration. These instruments are useful in the field of food safety, petrochemical, water quality checking, aquaculture, biological agriculture, environmental protection, and research and education.

Yatherm Ion meter comes in benchtop & handheld models with high precision and accuracy. Our all models have five-point calibration from low to high PPM with one ion electrode & one ATC with solutions. Our Instrument has a data storage facility with a USB port data transfer & printer facility.

Ion Meter vs Portable Ion Meter — Choosing the Right Format

Not every job happens at the bench, and that's the gap this range is built to cover. A benchtop ion meter like the A130 gives you a bigger 7-inch TFT display and multi-parameter testing (pH, ORP, ion, water hardness, conductivity, dissolved oxygen) all in one unit, suited to a fixed QC or research station. A portable ion meter like the 321-Series trades some of that for battery power and a compact 300g body, so you can carry it out to a field site, a tank, or a production line. As an ion meter manufacturer, Yatherm builds both formats around the same core accuracy, so results stay comparable whether the test happens on the bench or in the field.
