Range: 0.0 to 20,000NTU (3,000NTU limit on NEP260, 90°
probe), over four ranges automatically determined.
Display: 2 line, 16-character dot matrix alphanumeric
liquid crystal display.
Display Language: English standard, other languages available
Turbidity (NTU) - default
Relative Turbidity Reference (NTU)
Relative Turbidity REL (Turbidity - Relative Turbidity Reference)
Date/Time - default
Reading: Updated approximately every 1 second.
Averaging period: 0.5 second or 8 seconds nominal – user
Auto Range Steps:
1 <0.1 to 20NTU
2 <1 to 200NTU
3 <10 to 2,000NTU
4 <100 to 20,000NTU (using NEP280, 180° probe only)
Repeatability: 2% ± 1 digit on all ranges.
Data Logging: User set for one reading every 1 to 90 seconds
or minutes. All readings stored in the Notepad.
Notepad: 100 readings each with time and date.
Setup Procedures: Menu driven, including:
Analogue Output range selection
Reference Turbidity value
Setting date and time
Setup Memory: Non volatile EEPROM.
Clock: Calendar clock displays date and time. Year 2000
Good Laboratory Practice: All readings as well as calibration
constants are stored together with the Time and Date and can be
recalled at any time.
