VoluCheck 10K

VoluCheck 10K is a rapid deployed kit for volume verification of systems ranging between 10,000 and 100,000 gallons

PTSA is a colorless fluorescent dye that has been widely used for the determination of water volume for open and closed recirculating systems. The Pyxis VoluCheck PTSA System Volume Verification Kit comprises a laminated calculation and instruction sheet, Quantity 10 – 0.45 micron syringe filters and the following pre-weighted PTSA solutions: The Pyxis SP-350 (PTSA Only) or the Pyxis SP-700 (pH/Conductivity/ORP/Temp/PTSA) units should be used for measurement of the PTSA residual.

VoluCheck Application Details

The PTSA volume verification method is suitable in most recirculating water systems.

Closed systems treated with high levels of nitrite (>500 ppm) or containing high level suspended solids (>100 NTU) should be pre-flushed before using the PTSA sizing method to accurately determine the system volume.

These elevated levels can interfere with the PTSA measurement.System flushing until nitrite residual is below 100ppm or turbidity is below 40 NTU is recommended.

The Pyxis SP-350 or SP 700 can be used to check if the water is suitable for the method.
