HEINE 3.5V full size instruments and handles
are available
in 2 connecting systems:
AV connector: HEINE's exclusive patented automatic connecting system. Positive locking mechanism ensures a secure connection between Instrument and handle. | ||
TL (Twist Lock) connector: Welch Allyn 3.5V style connecting system. All HEINE TL Instruments and Handles are compatible with Welch Allyn products. | ||
The simplest way to distinguish between AV and TL Instruments is to
remove the Instrument from the handle and stand it up on a flat surface. TL
products will stand up and AV product will not (see images above). |
