All Marmonix products are factory calibrated prior to shipment. This calibration is valid for one year. An annual factory calibration is recommended. Marmonix does not include calibration certificates with our products. NIST calibrations with data can be purchased for an additional charge for most products. To send your meter to be NIST calibrated please contact our return department for a return authorization number and other return information.

Light Meters

Do you have a light meter that measures very high light levels?
Marmonix has Light Meters that can measure as high as 99,990Fc/999,900Lux with resolutions of 0.001Fc & 0.01 Lux. You can view the complete specifications of our light meters online. If you need more assistance, please contact our Tech Support for further assistance.
Do you have a light meter that measure light pulses/flashes or strobes?
The marmonix Light Meter is the only model that can measure light pulses/flashes or strobes. It has a peak hold feature that can capture short light pulses as fast as 100µS (100 microseconds).


Do I need to use the reflective tape?

Yes. The tachometer works by bouncing light off of the tape and needs this highly reflective surface for optimum results.

What tachometer will best fulfill my application – Photo, Contact, Laser?

For measuring objects that are hard to reach or dangerous, the solution is the photo or laser tachometer. The contact tachometers have to be used by pressing and holding against the rotating object. Only contact tachometers can measure linear feet.
