The main features of the PJ-Plus Profile Projector include the LED illumination system, stepless illumination adjustment, and a built-in digital XY counter. Possibly the best feature of the PJ-Plus Profile Projector is the brand new LED illumination method. By replacing the older halogen bulb lighting system with LED illumination negates the need for the internal cooling fan. Without the cooling fan, the PJ-Plus Profile Projector does not let in as much oil, mist, dust, and other contaminants which makes the tool perfect across normally challenging measurement environments. The stepless illumination adjustments of the PJ-Plus Profile Projector replaces the older 2-step illumination adjustment, which reduces the variation that occurs in color temperature and improves the sharpness of resulting images. Finally, the built-in digital XY counter uses easy-to-read characters to improve the speed and accessibility of the digital readout. Because of the XY counter, the PJ-Plus Profile Projector does not require an auxiliary DRO.
