I wonder what 3rd party certification would cost. Industries that use sensors like this frequently require annual recertification, so there are typically multiple testing houses and competitive prices.
- jacquesm 3y agoThere is a huge difference between calibration and certification. Calibration means that your instrument gives you absolute rather than relative output. Certification means that your instrument is precise enough to be used for specific procedures. Calibration can be done in house, certification is usually the domain of some certification institution and can be extremely expensive depending on the kind of gear.

A high-end, stable, double-wall PH-meter or finding a cheap way to build single-wall PH meters ? https://www.instructables.com/cheap-DIY-electronic-pH-meter/ https://www.instructables.com/cheap-DIY-electronic-pH-meter/ You explore the solution-space, and suddenly, out of nowhere it changes your perspective on another aspect, and you realize you may not need a spectrometer at all to measure ion concentartion in aeroponic nutrient solutions. http://jupiter.plymouth.edu/~jsduncan/courses../2011_Fall/InstrumentalAnalysis/Labs/9-IonSelectiveElectrodes.pdf http://jupiter.plymouth.edu/~jsduncan/courses../2011_Fall/In...
