Turbidity Standards
Only use AMCO or formazin standards with the TC-3000. StablCal
â
standards
below 50 NTU should not be used to calibrate the TC-3000. The diluent used in
StablCal
â
standards has a different refractive index than traditional formazin standards
and will affect the results. The concentration of the calibration standard should be
similar to the expected concentration of samples that will be tested. The following
standards are available from LaMotte Company:
1480 0 NTU Standard, 60 mL (EPA and ISO)
1484 1 NTU Standard, 60 mL (EPA)
1481 1 NTU Standard, 60 mL (ISO)
1485 10 NTU Standard, 60 mL (EPA)
1482 10 NTU Standard, 60 mL (ISO)
1486 100 NTU Standard, 60 mL (EPA)
1483 100 NTU Standard, 60 mL (ISO)
