## Description

Product Description The Extech LT300 light meter can determine whether you have adequate illumination to protect workers, students, visitors, patients or attendees of different venues. This handheld instrument measures up to 40, 000 fc (or 400, 000 lux) utilizing a remote light sensor connected via 12 in. Coiled cable (expandable to 24 in.). A prominent LCD readout displays a digital calculation and complementary analog bar graph for quick, reliable assessments. Complete with 9V battery, light sensor with protective cover, protective holster, and soft case. Insufficient lighting can create security risks or result in OSHA crackdowns. From the Manufacturer The Extech LT300 Light Meter reads cosine and color corrected measurements and features min/max and a data hold function. It has a wide range up to 20,000Fc or 200,000 Lux with a high resolution to 0.01 Fc/Lux. The relative mode indicates a change in light levels and the peak mode captures the highest reading. It has a remote light sensor on a 2 inch coiled cable and is expandable up to 24 inches. This meter utilizes the precision photo diode and the color correction filter. Also, it has a large LCD display screen with an analog bargraph and a backlight for readings in low light levels.

Review: Works Great - This unit is working great for my intended purpose (measuring shade on hiking trails). I have connected its voltage output to an analog data recorder so I can view the time-varying light intensity levels on my laptop. The unit has been working great for several weekends of hiking, and does correctly identify shade/sun conditions. My only problem is that the switches are not recessed, so the unit got jostled in my backpack and went into a mode where the data resolution became inadequate for my needs, however I bought a switch cover to fix that issue.
Review: Works great, sensitive - Works great, sensitive, durable and very affordable. If you just need to know relative light levels and are not concerned with hyper-accurate values, you can't beat the Ex-tech LT300. For me this a very good QA/QC tool for comparing scientific instrument consistency.

## Questions & Answers

**Q: Can you give me a calibration certificate with this unit?**
A: 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?**
A: 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?**
A: 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?**
A: I think the question needs to be directed to Extech.  I'd be interested in their answer.

### ⭐⭐⭐⭐⭐ Great meter
*by P***M on September 7, 2013*

Love is a strong word, but I more than "like" this little meter, so "love it" it is. I chose this meter for my business to measure ambient light in rooms used to test people's eyes. It is extremely accurate, as I periodically test it against another digital meter and a manual needle meter used in photography. Everything is great about the product except that I have to manually calculate the reading I need because of my specific industry. Only units that are twice the price or more provide the specific calculation I need with the flip of a switch. But I have one such unit, and everytime I compare the readings of both machines, they are dead-on with each other. A little inconvenient, but worth it to me since this unit was about $300 less than my other light meter.
