Pyxis 31125 Monochloramine/Nitrogen-Ammonia Low Range Secondary Verification Kit

The Pyxis Lab® Monochloramine/Nitrogen Ammonia verification standard kit is specifically designed to be used for secondary standard verification to check the accuracy for the Monochloramine/Nitrogen Ammonia Indophenol method (Low Range) on our colorimeters (SP-200, SP-910, SP-800). The secondary standard kit includes four sealed glass vials, an instruction sheet & 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 SP-Series colorimeters. Additional vials containing varying concentrations are also provided and listed below:

Monochloramine Low Range

• STD0 (For Zeroing)
• STDA (0.50mg/L – NH2CL)
• STDB (1.00mg/L – NH2CL)
• STDC (2.50mg/L -NH2CL)

Nitrogen-Ammonia Low Range

• STD-0 (For Zeroing)
• STD-A (0.10mg/L – NH3S)
• STD-B (0.20mg/L – NH3S)
• STD-C (0.50mg/L – NH3S)

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. 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.
