The HI84530-55 is a 230 mL bottle of pump calibration standard solution that is used for both low and high range determination of acidity in water.

Titratable acidity in waters, as performed on the HI84530 mini titrator, utilizes a simple sample preparation, a high quality titrant dosing pump, potentiometric endpoint detector, and automatic computations. To maintain the high precision of the titrator, a simple pump calibration procedure is required. A change of measurement range requires a different titrant along with a pump recalibration. The pump calibration involves the analysis of a known volume of a known solution and compensates for changes in pump dosing that may occur due to many factors including tube stretching or aging. This procedure should be performed regularly with the HI84530-55 pump calibration solution to accurately determine acidity levels in water.

Replacement reagents required to operate the HI84530 include:
 

	Low Range - 15 to 400 mg/L as CaCO3	High Range - 300 to 4000 mg/L as CaCO3
Pump calibration standard	HI84530-55	HI84530-55
Titrant solution	HI84530-50	HI84530-51
Additional reagent*	HI84530-60	HI84530-60

* Used with samples containing hydrolyzable salts or polyvalent cations (such as chromium, iron, manganese)
