The Interrogator 4210 from World Energy Labs is an electrochemical battery analyzer that measures sulfation, dryout, voltage and impedance. Voltage and impedance are lagging indicators. By the time there is a significant change, your batteries are most likely beyond the point where corrective action can be taken. But the chemical properties sulfation and dryout are much more sensitive leading indicators of battery health. By identifying early sulfation and dryout, corrective action can be taken that will ultimately extend the life of your batteries.
The Interrogator, meets all the critical needs of battery test instrumentation. It is easy to use and offers fast test measurements. The analyzer informs the user what corrective action needs to be taken to prevent failure
