This is a well made meter with some nice features for a reasonable price. The data logging is good for unattended recording. The button push memory capacity is great if you need to record multiple readings but can't write them down as you go...like floating in a swimming pool:) The things we do for a living! Put it in a shallow plastic tub (oil drain tub), lay a towel in it to absorb any water that splashes, seal the meter (not the head) in a zip-lock baggie, throw on a floatation vest, and get paid to go for a swim! The software is pretty basic and hasn't been updated since 2007, but it works for what it is supposed to do, I am currently on Windows 7 and it works fine.

Works well, easy to use

Excellent product. Easy to communicate with the serial port and control the device from my computer. Asked the manufacturer for the serial protocol and they happily sent it to me. Would definitely recommend.

accurate easy to use

Great product and good price. I use it for light studies. The software is very useful and easy to use

Works great, still figuring out some scales on light frequencies and additional settings. Have not tried the data logging yet.

Excellent meter that is easy to use. Compact and case protects the device well during transport!
