Product news
Metrohn has introduced a new maintenance free electrode for pH measurement and titration. The Ecotrode Gel has an innovative aging indicator which tells the user whether the sensor is still good to use.
The main properties of the Ecotrode Gel:
• maintenance-free electrolytes: refilling or checking the electrolyte not necessary
• aging indicator: decolorization of the white electrode gel tells users exactly when replacement of the sensor is due
• ideal for routine measurements

pH Meters and ElectrodesIon and pH meters are electrochemical equipment used to measure the pH (acidity or alkalinity) or specific ion concentration of a solution. Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis. Find the best pH meters and electrodes in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.pH and Conductivity MetersIon and pH meters, used for electrochemical techniques and measurements, measure the concentration of specific ions using electrodes (probes) and a meter. Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
