Review on π₯οΈ Enhanced Digital Monitor Calibration for Professionals by Edwin White
Not exactly. waste of money.
Varies constantly. Instructions x how to use the product and how to calibrate it are not clear. The price is steep x for such a poor quality product. I used to use dissolved oxygen meters. As a result, I had to hire a professional dissolved oxygen meter. Don't waste money.
- Accurate dissolved oxygen readings
- Available in white only
