Excellent multifunctional device

This unit works great only issue was trying to update the firmware. Windows 11 didn't want to recognize this device and wouldn't let me update the firmware. I did find a workaround and ended updating the firmware using an Android phone. Now the unit went from very good to excellent.

Very innovate & affordable measurement instrumentation!

I very much enjoy 3 different instruments that I purchased over the last 2 years from FNIRSI. Affordability, rich features, ease of use are key FNIRSI strengths. The build quality (plastic) is the only weakness, but it is understandable, due to very affordable price tags. I look forward to using more your versatile range over the coming years.

Good for the money

I think the English font needs to be updated from 1997 to a more modern font to make the display look nice. but the unit functions as expected.

Very nice radiation unit.

At a great price, the radiation detection is excellent. With a calibrated sample, it reacted appropriately. A very handy unit.
