Description
Tannins are naturally occurring organic compounds that can turn water yellowish and leave an earthy or musty odor. The Crystal Quest Tannins Test measures tannin and lignin through a mail-in analysis at National Testing Laboratories, with a minimum detection level of 0.5 mg/L.
Highlights
- Laboratory measurement of tannin and lignin
- Minimum detection level of 0.5 mg/L
- Helps explain yellow tint, musty odor, tangy aftertaste or staining of laundry and fixtures
- One 500 mL bottle keeps sampling simple
- Results are reported against EPA standards
Details
