The Extech EA30 light meter has a compact and robust design and a large display. Several large measuring ranges: 400,000 lux in 5 ranges and 40,000 Fc in 4 ranges. The measured value memory freezes the MIN/MAX values on the display. Zero function cosine and color corrected measurements. Low battery and out-of-range indicator. Automatic switch-off saves the battery. The meter uses a precision silicon photodiode sensor with a 1 m (3 ft) coiled cable for easy storage. Included are an integrated stand, off-center sensor with protective cover, rubber protective cover and 6 AAA batteries.
