pH Amplifier for PowerLab
The pH Amplifier is a dual front-end amplifier for PowerLab suitable for use with pH, ion selective and potentiometric redox electrodes. It can be used as a basic pH meter, or in conjunction with the in-built temperature amplifier to provide full temperature compensation.
The FE165 pH Amplfier is a dual front-end suitable for use with pH, ion selective and potentiometric redox electrodes. It can be used as a basic pH meter, or in conjunction with the in-built temperature amplifier to provide full temperature compensation
With a suitable electrode, parameters such as pH, redox potential, dissolved carbon dioxide and ammonia can be measured in aqueous solution. Ion selective electrodes are available for many ionic species including sodium, potassium, calcium, chloride, fluoride, nitrate and sulfide.
Compatibility:
The pH Amp is compatible with all current PowerLab and MacLab models.
