CT4665D Portable Battery Tester 0.00001V~1000.00V
CT4665D Portable Battery Tester 0.00001V~1000.00V
CT4665D Handheld Internal Resistance Battery Tester is the company’s key high-speed tester for accurate battery internal resistance and voltage test in the battery industry.
As a handheld tester, the CT4665D is lighter and smaller than desktop instruments, but its accuracy and speed are comparable to the bench top tester because it shares the same circuit design of the classic CT4665.
Powered of lithium battery and dry battery, CT4665D can still work in the harsh field and air transport limited areas to facilitate the use of dry-cell battery.
CT4665D has a minimum resolution of 0.0001mΩ, maximum voltage and auto trigger voltage of 1000V and fastest test speed is 100mS.
