Chemical Resistant Permanent Reference Cell is recommended for measurement of electric potentials at test stations, connecting to TR units and has contact points for surveying purpose. The Permanent Reference Cell is designed with rugged ultraviolet and chemically resistant inert long ceramic tubing. The Permanent Reference Cell of model number Fontana 104 is designed with especially liquid gelled mixture which surrounds with copper coil reduces electrical resistance. Chemical Resistant Permanent Reference Cell can work for a specific temperature of -15 to 90 degree C.
Caltech Engineering Services is engaged in manufacturing Chemical Resistant Permanent Reference Cell.
