The instrument’s characteristics are the following:
Real-time display of the item
Waterproof flexible external probe (IP67)
Built-in white-light LEDs for operations in poorly lit environments
Image rotation (0° - 180°) on the display
Adjustment of brightness
Rechargeable Li-ION battery
USB input for battery recharge
Analog video output (PAL/NTSC) for the connection to external devices
Electronic image zoom
