VMM measuring instrument
VMM measuring instrument is a voltmeter developed specially for application with FORCE Technology’s ERE 20 reference electrodes, used for assessment of a cathodic protection system and for monitoring of corrosion in reinforcement in concrete structures. VMM is characterised by its built-in data logger for registration of potentials without using a computer with a memory of up to 1024 registrations. The VMM measuring instrument developed for measuring on ERE 20 reference electrodes.
The measuring instrument is available both with memory (VMM measuring instrument) and without memory (VMC measuring instrument). Both versions of the voltmeter has a very high input impedance (> 100 MΩ) which is required in order to perform these potential measurements in concrete structures.
