Traceable® Light Meter Keychain Complete
Description
Pocket light meter reads from 0.01 to 99,999 lux (resolution
of 0.01 to 1) and 0.001 to 9,999 foot-candles (resolution 0.001 to 1).
Accuracy is ±3% plus 10 digits. Bright 1/2-inch high display
makes for an easy read.
The simplicity of the four-button operation eliminates the
need to refer to directions. Functions are on/off, hold (freezes the
display reading), lux/footcandles, and range (automatic or manual). By
simply pressing a button, the meter will automatically zero itself for
total darkness. Handy key-chain makes it easy to carry in your pocket,
and foldable style insures the sensor and keys are always protected.
To assure accuracy an individually serial-numbered
Traceable® Certificate is supplied to indicate traceability to
standards provided by NIST (National Institute of Standards and
Technology). Precise photodiode and color-correction filter provide
accurate cosine-and color-corrected measurements. Sensor diameter is
5/16 inch. Photocell’s response time is less than a second.
Unit is supplied with key-chain, Traceable® Certificate,
and 3-volt lithium battery. Folded size is 5 x 1-5/8 x 3/4 inches,
weight is 3-1/2 ounces.
