Ion Meter

Multi-parameter Ion meter with PH/Ion/ORP/ water hardness

Ion meters are specially designed for the detection of particular ion concentration in a solution. Yatherm Ion meter manufactured with detection of multi Ions ( Fluoride, Calcium, Sodium, Chloride & Nitrate), Ph, ORP & Water hardness with 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.

pH Mode:

• The standard benchtop pH/ion meter is designed in a 7 inch TFT display.
• Options Available for pH buffer group (USA/NIST/DIN).
•  Self Diagnosis with pH slope.
• ATC provides precise reading over the entire range.
• References of pH to 25°C.
• Indicative alarm when reading range is beyond the limit.

ORP Mode:

• Designed for one-point calibration.
• Absolute millivolt modes give reliable ORP readings.

Ion Mode:

• designed with selected ion measurement methods, including direct reading, addition, subtraction, sample addition, and simple subtraction.
• Yatherm Ion meter designed to take readings in ppm, mg/L, mol /L, and mmol/L.
• Designed with 5 points calibration with 8 concentration points.
• Self-detection of ion-selective electrode.
• Electrode management is capable of storing the 3 slopes and recalling the calibration data of each electrode.
• The calibration report provides the details of the calibration standard and electrode slope.

Water Hardness Mode:

• Two to five points Calibration from Low to high concentration like 0.001 to 0.01 to 0.1 to 1.0 to 10.0 to 100.0 to 1000 mg/L
• Options for Choosing measurement units according to the Nation (German degree, English degree, French degree, mmol/L  and mg/L) are used for water hardness measurements.


• Calibration Due Alarm.
• Stable reading indicator.
• Auto-Read features senses and locks the measurement endpoint.
• Computer or printer connection facility.
• Password protection facility.
• 1000 data storage facility.
• Restore factory setting option available.
