REED INSTRUMENTS R8100SD Light Meter
Measures visible light from 200 to 10,000 FC with silicon photodiode sensor and detachable probe
- Measures up to 100,000 Lux for bright environments
- +/-4% accuracy ensures reliable readings
- Data hold freezes values for easy recording
- Auto power off extends battery life
- Detachable sensor with 36 in cord adds flexibility
Light Meter for All Visible Light
The REED INSTRUMENTS R8100SD measures illuminance across all visible light sources. A silicon photodiode with a colour correction filter provides readings in foot-candles and lux. The detachable sensor connects via a 36 in cord for flexible positioning. An LCD shows values and a data-hold function freezes the display for recording.
Professionals Needing Basic Illuminance Checks
Technicians verifying workplace lighting or maintaining HVAC environments can use this meter for quick spot checks. The 200 to 10,000 FC and 2000 to 100,000 Lux ranges cover common indoor and outdoor levels. Buyers who need peak-hold capture or a computer interface for logging should look at other instruments. The meter ships without a calibration certificate.
Measuring Range Decides Suitability
The single specification that determines fit is the measuring range of 200 to 10,000 FC and 2000 to 100,000 Lux with an accuracy of +/-4 percent plus digits. If the application demands readings outside these limits or tighter tolerance, this model will not meet the requirement. Power comes from six AA batteries with auto power-off to conserve life.

Questions about this item
What does the 10,000 FC upper limit mean when I am taking readings in a bright room?
The meter stops at 10,000 foot-candles, so any light stronger than that will simply show the maximum value.
Does the R8100SD use a standard data port to log readings?
The specification lists no interface, so the meter cannot output data to a computer or logger.
How long is the sensor lead and what does that mean for positioning?
The cord is 36 in, letting you place the detachable sensor up to three feet from the display.
