The Type 41100 is a low cost, portable meter designed to make direct-reading pH and millivolt measurements. The expanded feature allows both pH and millivolt scales to be expanded by a factor of 10. In addition to making pH and redox measurements with greater sensitivity, Type 41100 may also be used with all types of specific ion electrodes. The instrument is battery-operated (AC operation is optional), and features high input impedance, easy-to-operate controls, a 6-inch meter face, and direct connection for all types of electrodes. Electrode must be ordered separately. BNC Connector. Warranty: 1 year.
