เครื่องโฟโตมิเตอร์-ฟลูออไรด์ (Fluoride Photometer 0.0- 20.0 mg/L)
Fluoride (High and Low Concentration) Photometer with 585 nm LED
Fluoride is best know for preventing tooth decay. Water authorities often add fluoride to drinking water to maintain approximately a 1.0 mg/L concentration. Fluoride can be found naturally in ground water, particularly if a reservoir is in the proximity of draws of sea water. While fluoride does help prevent tooth decay, too little can be ineffective and too much can cause staining.
Two different photometers are available to cover the high as well as the low ranges. In addition to HI 93729 for low fluoride measurements of up to 2 mg/L with 0.01 mg/L resolution, there is also the option of HI 93739 which spans the high scale all the way up to 20.0 mg/L. Both meters are microprocessor based and measure only one parameter for added simplicity. The new HI 93729C kit provides you with all the necessary equipment for field measurement in a rugged carrying case.
