A dry secondary verification standard versus wet, the Hach Verification Quick Check (VQC) allows you to verify the calibration of the FilterTrak 660 sc in just 20 seconds—saving you time and money. Calibrations can be verified to below 100 mNTU or 0.1 NTU.

The FilterTrak 660 sc Laser Nephelometer measures ultra-low levels of turbidity and has the lowest limit of detection on the market. It can detect a turbidity change of less than 0.3 mNTU or 0.0003 NTU, providing you with confidence in your turbidity measurement.

The VQC is fully compatible with previously purchased FilterTrak models and is now available for immediate purchase.
