Note: This unit is calibrated every 2 years. NIST calibration is valid for 1 year. Contact RAECO Rents to confirm availability if required.

The Extech LT300 is a digital light meter with a measurement range of 1 to 200,000 Lux (0.1 to 20,000 Foot-candles), using a detachable CIE photopic-response photo sensor on a 12 in. coiled cable (expandable to 24 in.). Built-in functions include Max/Min recording, Peak Hold (captures pulses as fast as 10 ยตs), Data Hold, and Relative mode for differential comparisons. Large backlit LCD with bargraph display. Suitable for OSHA lighting compliance checks, illumination audits, and energy efficiency assessments in offices, factories, hospitals, cleanrooms, and schools.
