KW870 Car battery tester & car OBDII Diagnostic Tool 2 in 1.
KW870 Works on all 1996 and newer 12V gasoline and diesel that are OBD II
compliant.It can identify the cause of your CHECK ENGINE and perhaps fix it
without going to see your dealer. It also assists you in easily passing annual e
missions tests and SMOG CHECK. It covers full OBDII/ EOBD diagnostic func
tions for engine system. O2 sensor test, EVAP systems test, and board monito
ring test give you full control of your vehicle's running status,while a graphical
and numeric live data stream display will help you to find out the faulty sensor
readings.
KW870 Battery Tester can test all automotive cranking lead acid battery,
including ordinary lead acid battery,AGM flat plate battery,AGM spiral battery,
and Gel battery,Lithium battery etc. it adopts the state-of-the -art conductance
testing
technology
in the word to
easily,
quickly
and
accurately
measur
e
the
actual cold cranking amps capability of the vehicle starting battery,healthy
state of the battery itself,and common fault of the vehicle starting system and
charging system, which can help maintenance personnel to find the find the
problem quickly and accurately,thus to achieve quick vehicle repair.
It Support multi-languages,customer can select different language which
includesEnglish, French, German, Dutch, Spanish, Russian, Portuguese,
