Ion Meter ST 867P
The ST867P is a straightforward Ion Meter with the ability to measure Ion concentration using up to 5 calibration points.
Operation is extremely simple and can be mains or battery operated. Made entirely in the CANADA the ST867P is compatible with the impressive range of combination and half-cell Ion Selective Electrodes available from Dintok directION and represents incredible value for money compared to other Ion meters in the same class.
The ST867P Ion meter comes in a robust splash proof case and is designed to give results that are both accurate and reliable over a wide range of applications. Most laboratories measuring Ion concentration will also measure pH. The ST867P has the ability to operate as sophisticated pH meter with Automatic Temperature compensation (ATC) and automatic calibration.
The mV mode is ideal for Redox and titration applications and incremental ISE techniques such as Known and Sample Addition. Other functions include memory back up, temperature and slope inspection to check the condition of electrodes and standards.The RS232 interface allows direct printing of results or full external computer control.
The meter has a BNC connector which makes it compatible with most ISEs and pH electrodes. Dintok directION combination ISEs make analysis more straightforward as they do not require user maintenance and can be stored dry.

Precise Ion Concentration Measurement with Professional Ion Meters
Ion Meter ST 867P accurately measure specific ion concentrations in liquids with our range of Ion Meters—versatile, laboratory-grade instruments designed for environmental monitoring, food & beverage quality control, pharmaceutical development, clinical diagnostics, and industrial process management. Using ion-selective electrodes (ISEs), these meters detect key ions such as sodium (Na⁺), potassium (K⁺), ammonium (NH₄⁺), nitrate (NO₃⁻), fluoride (F⁻), chloride (Cl⁻), calcium (Ca²⁺), and more—with high selectivity, speed, and reliability.
Engineered for Selective and Sensitive Analysis
Our Ion Meters combine advanced potentiometric measurement technology with user-friendly interfaces to deliver results in mg/L, ppm, mol/L, or mmol/L, with detection limits down to 0.01 ppm depending on the ion and electrode. Compatible with a wide range of interchangeable ISEs, they support 1- to 5-point calibration using standard solutions and feature automatic temperature compensation (ATC) for consistent accuracy across varying sample conditions.
- Broad Ion Compatibility – Works with most common ion-selective electrodes for targeted analysis.
- High Accuracy & Low Detection Limits – Ideal for trace-level monitoring in drinking water, biological fluids, or process streams.
- Automatic Calibration & Stability Detection – Simplifies operation and ensures reliable results.
- Temperature Compensation (ATC) – Built-in sensor corrects readings to 25°C for standardized reporting.
- Data Logging & Connectivity – Store hundreds of readings; export via USB or Bluetooth on advanced models.
- CE & RoHS Certified – Compliant with international safety and environmental standards.
Trusted Across Scientific and Industrial Fields
From testing nitrate levels in agricultural runoff to monitoring fluoride in dental products or sodium in pharmaceutical formulations, Ion Meters provide actionable insights where ionic composition affects safety, efficacy, or compliance. Their robust design and intuitive operation make them suitable for both routine QA/QC and advanced research applications.
Whether you’re in a field lab or a GMP facility, our ion meters deliver the specificity and precision you need—ion by ion.
Measure what matters—with confidence in every ion.
