Model 9100-2 with Remote Control

The Palico 9100-2 system utilizes modern day technology to measure the electrical resistance of separators used in acid and alkaline batteries. Resolution is 0.1 milliohm for 2 square inch and 20 square centimeter apertures and 0.01 milliohm for the 5 square inch and 50 square centimeter apertures. Optional scaled digital display to tenths of milliohms makes possible rapid tests for quality control purposes in the lab or on the production line.

The measuring system is combined with a precision engineered electrolytic bath for soaking, handling and testing of separator materials. The 9000-9100 Bath and accessories allow tests of individual or multiple separators from .001" to .375" (.0254 mm to .95 cm) thick.

Reversing polarity test currents simulate battery conditions and are kept low, operating at 10% duty cycle to prevent heating and polarization of the test bath. A 4-terminal "Kelvin" measurement method is used to improve accuracy by extracting data without regard to the quality of the connection the test electrodes make to the electrolyte. It also cancels the effects of offset or battery potentials.

The bipolar current source and the voltage measuring circuits are isolated from each other and any control or output circuits. This isolation prevents erroneous or unstable readings when operating near welding stations or large electrical controllers.

A typical system will have a test cell resistance from 80.00 to 400.00 milliohms, depending upon aperture size and the temperature and composition of the electrolyte used. An offset option is offered to digitally subtract the test cell reading, allowing direct readout of the resistance change caused by the separator. The remote control box uses booted toggle switches for system control allowing easy operation with a gloved hand.

A perforated polypropylene separator stand is available to verify test techniques and system operation. It can be mailed from plant to plant if necessary to aid in correlation of test data.
