Reliable water quality testing starts with properly calibrated equipment. At Rockdale County Water Treatment Plant, the Stablcal® Calibration Set with RFID helps laboratory staff maintain dependable turbidity measurements.
🔬 What is turbidity?
Turbidity describes water’s cloudiness caused by suspended particles. Measuring it helps staff monitor how well the treatment process is removing those particles.
🧪 How do these standards help?
The set contains pre-mixed, stabilized formazin standards labeled 10, 20, and 600 NTU. These known reference values support instrument calibration and verification according to the manufacturer’s procedures.
📡 What does RFID do?
With compatible RFID-equipped instruments, the technology helps identify the standards and their associated information, making the process more convenient for laboratory staff.
💙 Why does it matter?
Proper calibration helps staff have confidence in the measurements used to monitor treatment. These small vials play an important part in the careful laboratory work behind our community’s water service!
