SECTION 1 DESCRIPTION

1.1 General Description

The Hach Model 2100P Portable Turbidimeter (Figure 1) measures
turbidity from 0.01 to 1000 NTU in automatic range mode with
automatic decimal point placement. The manual range mode measures
turbidity in three ranges: 0.01 to 9.99, 10 to 99.9 and 100 to 1000 NTU.
Designed primarily for field use, the microprocessor-based Model
2100P has the range, accuracy, and resolution of many laboratory
instruments. The instrument operates on four AA batteries or with an
optional battery eliminator. Rechargeable nickel-cadmium cells may
be used, but cannot be recharged in the instrument. The instrument
automatically shuts off after 5.5 minutes if no keystrokes occur
(does not influence operation). If this occurs, simply turn the instrument
on – the 2100P will resume operation as if the power had not been
interrupted. The instrument, all standard accessories, and the optional
battery eliminator may be conveniently stored in the carrying case.
