2100 Series Portable Turbidimeter
Laboratory Turbidimeters
Bringing laboratory-level performance on-site.
Lab-Quality Results in a Portable Unit
The 2100P Portable Turbidimeter performs at a level normally
associated with laboratory instruments. Its microprocessor-controlled
touch-key functions and patented Ratio Optical System bring
greater accuracy, sensitivity, and reliability to field testing. The twodetector
optical system compensates for color in the sample, light
fluctuation, and stray light, allowing analysts to achieve laboratorylevel
results with a wide range of samples, even under difficult
on-site conditions.
Direct Digital Readout of Results
The 2100P provides direct digital readout in nephelometric
turbidity units (NTUs), completely eliminating the uncertainty of
analog indicators and the need for calculations or interpolation
of calibration charts.
• Selectable signal averaging mode compensates for fluctuations in readings
caused by movement of large particles in the light path
• Pre-programmed calibration procedure, with microprocessor-controlled
adjustment of calibration curve. No potentiometers to adjust
• Electronic zeroing: compensates for electronic and optical offsets; no manual
adjustments are required
• Built-in diagnostics
accessible with
one keystroke
• Range: 0 to 1000 NTUs
• Direct digital readout
in NTU
• Meets or exceeds EPA
method 180.1 criteria
• Two-year warranty
Ideal for Regulatory Reporting
With a measurement range of 0 to 1000 NTUs and resolution to 0.01
NTU, the 2100P is ideal for regulatory monitoring, process control
applications, and field studies. Choose from three manual range
modes: 0 to 9.99, 0 to 99.9, or 0 to 1000 NTU. Or select automatic
range mode for samples that vary widely in turbidity.
Ready for Field Use
The 2100P comes field-ready with four AA alkaline batteries
(optional battery eliminator available), all necessary apparatus, a set
of primary and secondary standards, and a rugged carrying case.
The instrument itself weighs less than 0.45 kg (~1 lb). The complete
analytical package, including case, apparatus, standards, and
instructions, weighs just under 2.7 kg (6 lb).
