The REED R8130 is a wide-range light meter with a tethered sensor probe, reading up to 400,000 lux (40,000 fc) for demanding photographic, film and industrial lighting checks. Its LCD includes a 42-segment analog bargraph alongside data hold, min/max, peak and relative (delta) readings, with accuracy rated around +/-5% of reading plus 0.5% full scale. It runs on a single 9V battery with a 30-minute auto shut-off, and ships with a protective holster and soft carrying case. This item ships with an add-on NIST-traceable calibration certificate.
