Overview
The FieldMaxII family of laser power and energy meters includes models FieldMaxII-TOP, FieldMaxII-TO, and FieldMaxII-P. These devices feature a large, backlit LCD display and offer digital accuracy with analog-like movement for laser tuning. They are compatible with thermopile, optical, and pyroelectric sensors and can measure energy up to 300 pulses per second (pps). The meters are portable, with AC/DC operation and a rechargeable battery pack, housed in a compact and rugged enclosure.
