Pyxis Lab DPD Chlorine Secondary Verification Kit

Overview

The Pyxis Lab® DPD Chlorine Verification Standard Kits are specifically designed to check the accuracy for both Free & Total Chlorine DPD methods (Low Range and High Range) on our staple colorimeters (SP-200 OXIPOCKET™, SP-800 & SP-910). The secondary standard kits include four sealed glass vials, an instruction sheet and Certificate of Analysis (COA) with specific tolerances for each concentration. Included in the kits are the STD0 sample blank vial, which is used to zero the Pyxis Lab® SP-Series colorimeters. The precise concentration, along with the corresponding tolerance range of each vial in the kit is provided in the COA (Certificate of Analysis). Pyxis Lab® meters are calibrated at the time of manufacturing. These standards should be utilized on the meters routinely as a verification check on the unit accuracy per EPA guidelines. The results should be recorded. The Pyxis Lab® SP-Series should measure the concentration of the standards within the concentration tolerance range specified in the COA. Finally, if the concentration measured by SP-Series on any standard vial is outside the tolerance range, the SP-Series device may be calibrated using a primary or secondary chlorine standard or factory calibrated by contacting service@pyxis-lab.com. Additional vials containing varying concentrations are also provided and listed below: STD0 (For Zeroing) STDA (0.50mg/L or 2.00mg/L) STDB (1.30mg/L or 5.00mg/L) STDC (2.00mg/L or 8.00mg/L) Features Blank Vial, Three different standards within Typical Testing Ranges, Instructions and COA Case to House Standards for Future Use 1-Year Shelf Life
