Portable pH/ISE allow the flexibility to perform an ISE measurement with a portable even though the ISE measurement method is more suitable to a benchtop environment due to the addition of the ISA to lower the pH and the use of a magnetic stirrer to keep the sample homogenous. The portable pH/ISE meter has the ion charge and formula weight pre-programmed for concentration measurements.
Benchtop pH/ISE meters include a two channel option in which a pH probe can be connected to one channel and the carbon dioxide ISE to the other. The benchtop meters have the ion charge and formula weight pre-programmed for use with the carbon dioxide ISE. The benchtop meters also have incremental methods pre-programmed including the known addition, known subtraction, analyte addition and analyte subtraction methods
Electrodes & Probes
The carbon dioxide ISE is a gas sensing electrode. An ISA must be used to lower the pH of the sample in order to change any carbonates/bicarbonates to carbonic acid in which will dissociate into water and carbon dioxide as a gas. The ISE is a convenient way to measure carbon dioxide.
Solutions for carbon dioxide measurement include ISE standards and ISA for calibration and measurement.
Accessories include magnetic stirrers to ensure adequate mixing when using an ISE and the spare parts for the carbon dioxide ISE.
Chemical Test Kits
Several chemical test kits are available for measuring carbon dioxide from single parameter test kits to multiparameter test kit for water quality.
Reagents include the reagents used with chemical test kits and photometers.
