WARNING!

Because this instrument is used to detect and monitor materials and conditions which are listed by OSHA
or others as potentially hazardous to personnel and property, the information in this manual must be fully
understood and utilized to ensure that the instrument is operating properly and is both used and maintained
in the proper manner by qualified personnel. An instrument that is not properly calibrated, operated and
maintained by qualified personnel is likely to provide erroneous information, which could prevent user
awareness of a potentially hazardous situation for the instrument user, other personnel and property.

If, after reading the information in this manual, the user has questions regarding the operation, application
or maintenance of the instrument, supervisory or training assistance should be obtained before use.
Assistance is available by calling your nearest Bacharach Service Center.

1 INTRODUCTION

The Dioxor® II is a commercial-grade
portable instrument designed to display

concentrations of sulfur dioxide (SO2) gas
between 0 and 2000 ppm. This instrument
shows the presence of SO2 in a gas sample
by drawing the sample into its sensor cham­ber by a built-in motorized pump. Part
#19-7038 comes with a probe. Part #19­7043 comes without a probe (All non­probe related functions remain the same in
this instruction).

Figure 1. Dioxor II

Other features and accessories of the
Dioxor II include: A large, back-lit Liquid
Crystal Display (LCD), which allows the
display to be read in any lighting condition
from direct sun-light to total darkness; a
semi-detachable elastic strap that permits
the instrument to be either hand held, or
hung on nearby objects; a rigid stainless
steel probe with handle, connected to a
flexible hose with sample filter that allows
gas samples to be taken from cramped and
confined areas (alternate probes and
condensate traps may be used).

3 PREPARING THE DIOXOR II

FOR OPERATION

To prepare the instrument for operation, you
must install four “C” size batteries, and (if
desired) install the hose and probe as described
in the following paragraphs.

For your convenience, and to ensure that the
instrument will provide reliable SO2 indica­tions, the SO2 sensor is installed and the instru­ment calibrated on a known SO2 concentration
at the factory.

3.1 Battery Installation

Detach the elastic strap's metal clip at the bot­tom of the instrument, and slide off the battery
cover as shown in Figure 2. Then while observ­ing proper battery polarity, install four “C” size
batteries into the instrument’s battery compart­ment. (Recommended battery types: Duracell
Alkaline or equivalent). After the batteries are
installed, replace the battery cover and the
elastic-strap clip.
