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

Overview

The Pyxis Lab® Monochloramine/Nitrogen Ammonia verification standard kit is specifically designed for secondary standard verification. Verify the accuracy of the Monochloramine/Nitrogen Ammonia Indophenol method (Low Range) on our colorimeters ( SP-200, SP-910, SP-800 ). In addition, the secondary standard kit includes four sealed glass vials, an instruction sheet & Certificate of Analysis (COA) with specific tolerances for each concentration. The kits include the STD0 sample blank vial, which is used to zero the SP-Series colorimeters. Additional vials containing varying concentrations are also available. The precise concentration, along with the corresponding 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. As well as the standards being utilized on the meters routinely as a verification check on the unit accuracy per EPA guidelines. Furthermore, 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 need to be calibrated. It is done by using a primary or secondary chlorine standard. Also, it can also be done by contacting service@pyxis-lab.com and getting a factory calibration.
