This dual-unit visible light meter measures from 0 to 50,000 lux or 0 to 5000 foot-candles. The photovoltaic cell and microprocessor provide an impressive 0.4 second sampling rate and automatic-zero adjustment. Colour-correction filter and precise photodiode produce accurate cosine- and colour-corrected measurements over the wide range. Connect the analog output to a recorder to capture readings, 0.1 millivolt per digit (200mV max), or display current values on the large 1/2" high digital display. DATA HOLD allows you to freeze current measurements at the flip of a switch.

Traceable® products have an individually-numbered Traceable® certificate provided with each unit, that assures accuracy from our ISO/IEC 17025:2017(1750.01) calibration laboratory accredited by A2LA. It indicates traceability of measurements to the SI units through NIST or other recognised national measurement institutes (NMI) that are signatories to the CIPM Mutual Recognition Agreement. Each product goes through an intense vetting process before it can carry the Traceable name, thus saving you both time and money by not having to calibrate separately.

• Calibrated using a tungsten light source. If measuring another type of light source, the reading displayed on the meter will have to be manually corrected using the following factors: mercury - (reading x 1.05), fluorescent - (reading x 0.91), daylight - (reading x 0.95)
• Connect the analog output to a recorder
