Filter Paper

Pallflex T60A20 Filter Paper was used during developement and is sadly discontinued. We're testing https://www.amazon.com/7194-Non-Heat-Pallflex-Tissuquartz-Laboratory/dp/B0731SG18R.
You may send us a sample of your filter paper and we happily calibrate bcMeter with it!

Bill of Material for general purpose PCB (THT components & 12V DC Barrel Jack)
