Extech LT300 Light Meter & SL510 Sound Level Meter, Class 2 Compact

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.

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.

Nice inexpensive meter. Agrees with my other units and gives me an inexpensive backup.

Meter is easy to use and accurate. Works in many applications

I'm in the commercial lighting business, and I use this product for reading foot candles nearly every day. It's a bit bulky and I wish they'd figure out a way to incorporate the sensor into the unit so you're not always having to use both hands to use the device (the sensor is always flopping around while I'm using the device and juggling a notebook and so on). Seems to be well made and durable. Seems to be quite accurate. The device was more than I wanted to spend on such a tool, but it was recommended to me by others in the industry and it's living up to its reputation.

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.

I purchased two units, the units worked perfectly on the first day, on the second day one of the units stopped working.The service from Amazon was perfect I received a new unit after one day. 10 days after I received the replacement it also stopped working.

I was very surprise with it . nice packaging ... Value for the money

Buen producto

I have had this unit before. The cord to attach cap snapped off first day when it slipped from my hand. The wire insert is fragile, which is why I had to replace my original.Works well.

Bought for a store surveys. Worked well.

Excelente equipo para medir la intensidad de la Luz, confiable y exacto
