Review on Tachometer PEAKMETER Measurement Precision Indication by Zack Frazier

The build quality is better than I expected. Playing with this seems to work well in the sense that higher intensity results in higher readings. I can't say if they are accurate but I just wanted to compare some lights and just check the window ambient light values and when the light is on. Something like that. My only problem is that in some situations I want to point it at the light source (like a window) because the meter is very directional. He really just reads forward. Therefore, when I point it at the window, it's at an angle away from me and I can't read the screen. That's when I saw the meter readings with a cable attached. For me it would be the best choice. But if the solution is right for you, I highly recommend this meter.
