Description

Product introduction

High-performance multiparameter Water Quality meter contains 8 measurement modes, suitable for measuring pH, ORP, ion concentration, conductivity, TDS, salinity, resistivity and dissolved oxygen.


Features

pH Mode:
• Portable multiparameter Water Quality meter is equipped with a backlit LCD display.
• 1 to 5 points calibration with automatic recognition for USA, NIST and DIN buffers.
• Automatic electrode diagnosis shows the pH slope and zero offset.
Conductivity/TDS/Salinity/Resistivity Modes:
• 1 to 5 points calibration with automatic recognition for conductivity standards.
• Selectable cell constant (K=0.1/1/10), reference temperature (20/25°C), TDS factor, linear and
pure water compensations, seawater and practical salinity measurement modes.

Dissolved Oxygen Mode:
• 1 or 2 points calibration using the air-saturated water or zero oxygen solution.
• Salinity and barometric pressure compensations eliminate the measurement errors.

ORP Mode:
• 1 point offset calibration allows adjusting the displayed value to a known standard.
• Relative and absolute millivolt modes ensure the reliable ORP measurements.

Ion Concentration Mode:
• 2 to 5 points calibration, including the selection of 8 concentration points.
• Automatic electrode diagnosis shows the calibration points and slopes.
• Direct ion concentration readout simplifies the measurement process.
• Selectable concentration units (ppm, mg/L, mol/L) and ionic valency.
