Page 5: Overview
The Turb 2000 Series process turbidimeter allows for the measurement of the turbidity of drinking water and process water on-line. The White Light Turb 2000 and 2020 has been designed to meet the design criteria specified by the US EPA 180.1 on turbidity measurement. The infrared Turb 2100 and 2120 was designed to meet the design criteria specified in ISO 7027 and DIN 27027 for the measurement of the turbidity of a sample. -
Page 6: The Display
Overview Turb 2000 Series The display Figure 1 illustrates all the items that can appear on the display. The upper row of the display (1) is used for reporting the turbidity levels and to provide user guidance in the customer setting routine. The lower row of the display (2) is used to communicate error messages and provide user guidance. -
Page 7: Vapor Purge
Overview Vapor purge The Turb 2000 series is equipped with a continuous vapor purge system. A replaceable desiccant pouch in the lower portion of the instrument dries the air. System heat is used to warm the air. A fan inside the instrument continuously circulates heated dry air around the optical well and the flow through cuvette. -

Page 16: Operation
Operation Turb 2000 Series Operation This process turbidimeter allows for the on-line measurement of the turbidity of process water, swimming pool water and drinking water. The turbidity of the water is usually reported in Nephelometric Turbidity Units (NTU), but may be reported in Formazin Nephelometric Units (FNU). Readings above 1100 NTU will cause the display to flash indicating an over range condition.Readings above 1100 NTU... - Page 17 Turb 2000 Series Operation The security code (333) must be entered to gain access to CAL or CONFIG menus. Notice that the first number in the code is flashing; the flashing indicates that this is the number to be changed. Use the ...

Page 18: Instrument Calibration
Calibration standards If the Turb 2000 series will be used over the entire range of 0.02 to 1000 NTU a complete calibration as described below will be required. If instrument accuracy is only required below 10 NTU (below 1 NTU for Turb 2110), such as potable water, a calibration may be performed using only a 10 NTU and a 0.02 NTU standard (1.0 NTU and... -
Page 19: Calibration Procedures
Calibration procedures Note The displays in this chapter demonstrate the calibration procedure for Turb 2000, Turb 2020, Turb 2100 and Turb 2120. When calibrating Turb 2110 the displays for the first two steps show the corresponding values for the 10.0 NTU and 1.0 NTU calibration standards. -
Page 20: Calibration Error
Instrument calibration Turb 2000 Series 12. Insert the requested 0.02 NTU standard. Index the standard to the lowest value on the upper display. 13. Press the OK button to accept the calibration. 14. The lower display will count down the progress of the calibration step. -
Page 21: Instrument Offset
7. If the option was turned On, the upper row will display the offset required. This will add or subtract the value of the offset to the measured NTU value. As an example if the Turb 2000 series measures the sample at 0.16 NTU but the laboratory instrument reads the sample at 0.12 NTU, adding an offset of –0.04 would result in the instrument displaying 0.12 NTU. -
