• Sufficient for 50 tests at 200 ppm

Direct Reading Titrator (9859X72 and X73)

• For determining calcium, magnesium and total water hardness
• Range 0 to 200 ppm as CaCO₃ in 4 ppm increments
• Sufficient for 50 tests at 200 ppm

Direct Reading Titrator Method (9860A15 and A16)

• For determining low range total hardness of water
• Range of 0 to 10 ppm as CaCO₃ in 0.2 ppm increments
• Sufficient for 50 tests at 10 ppm

Drop Count Method (9860A47 and A48)

• For determining total hardness of water
• One drop equals 10 ppm or 1 gpg as CaCO₃
• Sufficient for 50 tests at 200 ppm or 20 gpg
