Direct reading of fluoride for use in: public water fluoridation control fluoride is known to help prevent tooth decay while too much fluoride is known to be bad for the teeth; the concentration recommended by the American dental association is 0.7-1.2 ppm; the MCL established by the EPA is 4.0 ppm; fluoride is naturally occurring and in some areas in the US the natural level exceeds 4.0 ppm. Large LCD simultaneously displays ppm of fluoride, temperature and analog bar graph indicator. Easy use for field or laboratory fluoride testing. Small sample/TISAB volume required for testing (10 mL). In compliance with EPA method 340.2.(Potentiometer ion selective electrode).
