The portable solution you need to optimize your water analysis program, anywhere, anytime.
The superior technology you expect in a spectrophotometer.
The ease of use you require to support all personnel.
The attractive price and value you want.
The DR/2400 Portable Spectrophotometer brings you the technically superior operation and innovative user interface of the popular DR/2500 Spectrophotometer, plus a design that makes it completely portable. Now you can have it all in your photometric water analysis program, whether it's municipal, industrial, environmental, or educational; in the lab, at the process site, or in the field.

FEATURES AND BENEFITS
Automatic wavelength selection and calibration —
Eliminate manual dialing and reduce errors.
"Favorite" programs menu — Store your frequently
used tests to your own short list for easy access.
More than 130 preprogrammed tests — Just call up the test you need, each includes operator prompting selectable in four languages; select "favorite" programs quickly; add up to 50 single-wavelength, user-generated calibrations.
High-performance optical system — Achieve testing
accuracy, instrument stability and longevity found in higher
priced systems.
Graphic user interface with touch-screen display —
Navigate easily through setup and testing with the touch of
your finger; replaces the traditional keypad, repetitive
scrolling, and keystroke combinations.
Comprehensive data management — Select time/date
stamp, operator and sample ID; collect up to 1000 data
points; download via RS-232 communication directly to
printer or computer.
Battery-powered/compact size — Benefit from
sophisticated spectrophotometer capability anywhere; line
power converter included with instrument.
Programmed accuracy checks — Improve test technique and results with built-in, software-assisted standard additions checks.
Update capability — Keep your hardworking system
updated with new Hach tests, using the plug-in Update
Module programmed with new test calibrations; you add the calibration to your instrument memory without tedious keying sequences.
Accessories as you need them — Pay only for the
options you need, including HachLink™ Software for data
formatting, the Pour-Thru Cell for convenient and accurate
high-volume testing, and a variety of sample cells to match your requirements. Available alone or as a completely
equipped portable laboratory: take your DR/2400 Portable Spectrophotometer wherever needed.

Depending upon your testing needs, you can select a DR/820, DR/850 or DR/890 Colorimeter, preprogrammed to test for at least 20, 50 or 90 parameters, respectively, and equally suited for skilled analysts who value the time they can save, or for operators with limited training who appreciate ease of use and accurate results.

The DR/890 Colorimeter is the most complete, most capable of the DR/800 Series, suited to a wide range of testing needs and offering all standard DR/800 Series features, including datalogging, user-generated procedures, advanced software, RS-232 capability (with optional Data Transfer Adapter), and a large custom display. The instrument performs more than 90 tests.

STANDARD FEATURES
Capable: three models (20, 50, or 90 methods) with
automatic wavelength selection
Preprogrammed: ready-to-use out of the box
Compact: true hand-held analysis, for use anywhere
Rugged: dustproof, waterproof, shockproof, worry-free
(designed to meet IP67 standards)
Powerful: full datalogging and RS232 interface capabilities
Simple: menu-driven, step-by-step analysis
Affordable: choose the instrument you need or select a
complete portable laboratory
KEY BENEFITS
Easy-to-use software offers push-button method selection,|
automatic wavelength selection and a preprogrammed
method timer. Results are displayed immediately, with no
countdown. The display is very easy to read, and includes
result, units and parameter name.
The instrument retains the selected method until a new
method is entered, even after the DR/800 is turned off and
then back on at a later time. This allows a series of analyses to be performed for the same parameter without reselecting the method.
Datalogging capability includes push-button record-keeping. Store data in the field for later access, with no delay in testing. The instrument stores up to 99 measurements in internal, non-volatile memory. Data stored includes date/time, parameter, program number,
concentration/absorbance/ %T, sample number, and
instrument serial number, all of which greatly simplify record keeping tasks.
Results are displayed directly in units of concentration,
absorbance, or % transmittance. In many methods,
concentration in alternate chemical forms is also available.
For example, phosphate readings are available as P, PO4
and P2O5. Displayed results can be changed from one form to the next at the touch of a button.
User-program feature allows users to generate up to 10
custom procedures, with up to 12 data points each, and
store them in non-volatile instrument memory for later use.
Advanced software includes the ability to automatically correct for reagent blanks, and the option to fine-tune
calibration curves with the standard adjust feature.
Batteries provide self-contained power for field testing.
Nominal battery life is 6 months with standard AA alkaline
batteries. Rechargeable alkaline batteries are also available.
The optional Data Transfer Adapter (DTA) fits onto the
instrument and accepts data sent from the instrument's
infrared light emitting diode (LED) transmitter. The DTA
converts data to standard RS232 format and connects
directly to a computer or printer. Data can be printed or
downloaded at any time--after it is stored in the instrument
or while it is being collected.
