The portable APERA PION400 pH/mV/ion meter is a rugged, professional-grade solution designed for high-precision water quality analysis. The IP57-rated, water-resistant device combines laboratory-grade accuracy with the durability required for demanding field applications, enabling reliable measurement of pH, ion concentration, oxidation-reduction potential (ORP), and temperature.
The ion-selective electrode is not included here and would need to be ordered separately.
- Fast and precise measurement of pH and temperature (accuracy: ±0.01 pH, range: 0 to 14 pH, 0 to 100°C)
- Equipped with the 201T-S pH electrode with integrated temperature measurement
- Water and dust-proof (IP57) for harsh environments
- Quick and easy 1- to 3-point calibration
- Large, illuminated LCD simultaneously displays the conductivity value and the temperature, as well as additional measurement and calibration information
- Self-diagnosis supports calibration or troubleshooting
The measuring device has the EC marking and a two-year guarantee on the device (six months on electrodes).
