caution statements. Failure to do so could result in serious injury to
the operator or damage to the equipment.
To ensure the protection provided by this equipment is not
impaired, do not use or install this equipment in any manner
other than that which is specified in this manual.
Use of Hazard Information
If multiple hazards exist, this manual will use the signal word
(Danger, Caution, Note) corresponding to the greatest hazard.
DANGER
Indicates a potentially or imminently hazardous situation which,
if not avoided, could result in death or serious injury.
CAUTION
Indicates a potentially hazardous situation that may result in
minor or moderate injury.
NOTE
Information that requires special emphasis.
Precautionary Labels
Read all labels and tags attached to the instrument. Personal
injury or damage to the instrument could occur if not observed.
This symbol, if noted on the instrument, references the
instruction manual for operational and/or safety
information.
Safety Precautions
Hot Surfaces. Touching the reactor block surfaces and vials
while hot can cause serious burns.
Protective Earth Ground. This product requires a protective
earth connection. If not provided with a plug on a cord,
connect positive earth to this terminal (U.S. cord set
provides ground).

Safety Precautions
Safety Equipment
Use protective clothing when operating the reactor, including
goggles or face mask, and gloves.
Reagent Spills
Clean up spilled reagents immediately. If reagent contacts skin,
rinse the affected area thoroughly with water. Avoid breathing
released vapors. Read the Material Safety Data Sheets (MSDS)
supplied with each reagent for complete chemical information.
Fire Hazard
Avoid the presence of flammable liquids near the operating
reactor. A fire hazard could be created.
Power Cord
A power cord suitable for 115 V ac line voltage is supplied with
the DRB 200.
DANGER:
Do not allow the power cord to pass under the instrument.

Section 1 Introduction
The DRB 200 is supplied as two models, with either one or two
heating blocks (Figure 1). The heating blocks can heat solutions
in round vials of various sizes at 37–165 °C for a period of 0–480
minutes. The small, 16 mm diameter openings on the heating
block are suitable for Hach COD, Unicell, TOC, and Test N’
Tube tests. The larger, 20 mm diameter openings are intended for
sample preparation reaction vessels, using the Metals Prep Set.
The DRB 200 has 6 stored and 3 programmable temperature
programs.

1.1 Front Display
The instrument is operated using three touch-sensitive keys
located below the display (Figure 1). The function of the key
depends on the display. If no function is shown for a specific key,
that key is not currently active.
The actual temperatures of the heating blocks and the remaining
time are visible in the display while temperature programs are
active.
