BENCHTOP TURBIDITY METER FOR LABORATORY USE
The TB200 benchtop turbidity meter measures turbidity in NTU, FNU, EBC, and ASBC units, with a selectable total suspended solids (TSS) mode in mg/L. It uses a 90-degree nephelometric measurement method, supports 2- to 7-point calibration, and stores up to 200 readings for review or transfer to a computer.
1. Wide range — measures turbidity from 0 to 2,000 NTU/FNU, with selectable EBC and ASBC units
2. TSS mode — supports a TSS measurement mode using a user-set conversion factor
3. Calibration — offers 2- to 7-point calibration with Formazin standards; factory calibration is provided
4. Auto-read and storage — auto-read senses a stable value and locks the reading; store up to 200 records and transfer them to a computer over USB
5. Display and protection — includes a 4.5-inch TFT LCD, password protection for setup and calibration, and adjustable display brightness
The display shows the measured value with the active unit, and the keypad below it carries the escape, calibration, and navigation keys. The sample vial is placed in the compartment under the lid.
