Extech401025 Foot Candle/Lux Light Meter

Q: Can you give me a calibration certificate with this unit?

LT300 version with NIST costs $289.00 in our valuetesters store. There is a two week lead time, as each unit needs to be calibrated manually.

Q: What is the lowest fc reading this unit will take? Will it measure as low as 0.02 fc?

We have used this device on almost a daily basis since we examine potential customer sites for our lighting products. We found that the greatest consistent resolution you can get .05 increments reliably as compared to other like devices in the same setting. A good product in our opinion.

Q: what is the conversion formula for lux to PPFD for this unit?

Multiply the Lux by the conversion factor to get PPFD. For example, full sunlight is 108,000 Lux or 2000 µmol m-2 s-1 (108,000 ∗ 0.0185).

Q: I can post the calibration certificate?

I think the question needs to be directed to Extech. I'd be interested in their answer.
