Optical Power Meter -70~+10 dBm Fiber Light Meter for Testing 6 Calibrated Wavelengths, 68g Light Weighted

As a fiber installer I’m required to test light. Instead of carrying my meter I check the light with this and make sure the installation can happen.Screen is easy to read and has a backlight for dark areas.2 triple A batteries are required for operation.The shape is a bit odd, thin pear like but fits in the hand comfortably.Cheap housing but expected for the price you pay.Accuracy is a bit off, so if something precise is required for you. Expect to pay more.Be sure you’re measuring the proper wavelength.

This little meter is just -1 off than my $$$ big Optimeter... when I'm climbing poles and need to hook up fiber drops, it's so much easier bringing this small item than the very large and pain in the @#$%& Optimeter. So when I know I got light, I'm good to the slacknid at customer prem then the FJ. Definitely easier to use. This gives me ready within 5 seconds turn it on. While the large OptiMeter takes about 3-5 minutes for a reading. So there is a -1 difference between the handheld and the large . It's negligible. Overall happy with this product. Using it about 4 months now.****????"""""""""???????""""""""""""""""Note:Only downside.... wish they provided a carrying pouch for your belt... but you can't have it all

The unit measures 1.4dBm too long, but serves it's purpose as a very portable measuring device.

I really like this product. I work in with fiber optics every day and this product been one of the best investments I made. One thing that I really like about this product is the potability it’s small but still has all the things that I need.

I tested this along side the company provided very expensive light meter and they are about the same maybe a decibel or two off. Would definitely recommend

I love it. Way more practical than my company-issued Jonard OPM, and only ~.01 dB difference when the readings are compared. The carrying case holds it nicely on my belt.

For the money, this was worth every penny. It’s compact light weight. Makes testing terminals and hubs so easy. I love it!

I work with a lot of Fiber Internet, shows the correct readings of the Light level. Saves time vs using a Meter. And it has a light at night that i wish it could be better, i can see but not too well at night. But it makes a difference in the field.
