Features and Benefits
Choose from Three Models
Depending on 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.
All three models include the same convenient features:
auto-wavelength selection, datalogging capabilities and
user-generated calibrations. Refer to the table on pages
3-4 to select the colorimeter that tests the parameters
you require.
These durable, hand-held, filter photometers are designed
specifically for the rigors of on-site testing, with rugged
components and waterproof, dustproof, chemical-resistant
housings. DR/ 800 Series Colorimeters offer simple,
push-button program selection and step-by-step prompts
that guide users through the testing procedure. These
instruments are equally appreciated by experienced analysts
who value test efficiency and by operators who require ease
of use with accurate results.
Advanced Features Add Value
• Easy-to-use software offers push-button method
selection, automatic wavelength selection and a
preprogrammed method timer. Result, units, and
parameter name are displayed immediately, with no
countdown. The large digit display is very easy to read.
• The DR/ 800 retains the selected method until a new
method is entered, even if it is turned off and then back
on. This allows a series of analyses to be performed for
the same parameter without reselecting the method.
• Datalogging capability includes push-button record
management. Easily store data in the field for later access,
with no delay in testing. The instrument stores up to 99
measurements in an internal, non-volatile memory. Data
stored includes date/ time, parameter, program number,
concentration/ absorbance/ % T, sample number, and
instrument serial number.
• 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 a non-volatile instrument memory for
later use.
• Advanced software includes automatic correction for
reagent blanks and the option to fine-tune calibration
curves with the standard adjust feature.
• Batteries provide self-contained power for field-testing

Accessories Simplify Data Management
The Data Transfer Adapter ( DTA) fits on the colorimeter and
accepts data sent from the instrument’ s infrared LED
transmitter. The DTA converts data to a standard RS-232
format and connects directly to a computer or printer. Data
can be printed or downloaded conveniently, after storage or
during collection.
DR/ 800 Series Colorimeters are compatible with HachLinkâ„¢
Software, a Microsoft® Windows® compatible application
that links instrument and computer, providing a convenient
means of accessing and managing test data. Information
including date/ time, parameter, concentration/ absorbance/ % T,
sample number, operator identity, and instrument serial
number is accepted and stored in either text or tabular
( spreadsheet) format, and can be easily transferred to
popular spreadsheet or word-processing applications.
Easy Quality Control
DR/ Checkâ„¢ ABS Standards are the optional choice to verify
the performance of your DR/ 800 Colorimeter in seconds.
Standards are formulated with neutral density gel that
produces similar absorbance readings at any wavelength.
For all parameters at all wavelengths, running three
secondary absorbance standards will verify your
instrument’ s calibration easily, anytime.

Features and Benefits continued
Affordable COD Analysis
All three models include Hach’ s Manganese III COD procedure ( mercury-free version) .
The DR/ 850 Colorimeter also performs our traditional USEPA-approved high-range
COD procedure, and the DR/ 890 Colorimeter performs both low-range and high-range
USEPA-approved COD procedures. An adapter suitable for COD vials and Test ’ N
Tubeâ„¢ ( TNT) vials is included with each instrument.
Push-Button Operation Speeds Analysis
Using Hach prepared reagents, testing is normally accomplished in just a few minutes,
following this simple procedure:
1. When turned on, the instrument automatically recalls the last program used. To
change programs, press the program key and enter the program number from the
procedures manual. The instrument displays the program number, parameter, units,
and the zero icon.
2. Prepare the blank ( zero) according to the procedure, place it in the instrument, and
press the zero key. The instrument displays the zero and the read icon.
3. Prepare the sample according to the procedure.
( An internal timer is preprogrammed for methods that require a fixed reaction time.
Timer duration is automatically displayed for the selected procedure; simply start
the timer at the start of the reaction.) After reacting the sample, place the sample
cell in the instrument and press the read key.
4. The instrument displays the result in concentration units. The user can also toggle
the ABS % T key to display absorbance or % transmittance. Some results can be
displayed in alternate chemical forms ( e.g., Cr may be displayed as mg/ L CrO4 or
Cr2O7) . Scroll through available forms by pressing the CONC key.
5. Save the results by pressing the store key. The instrument will store up to 99
measurements in an internal, non-volatile memory. Results may be printed or
transferred to a computer at any time using the Data Transfer Adapter.
