3700 Portable Samplers
Section 1 Introduction
1.1 Introduction
1.1.1 3700 Standard
Description
The 3700 Standard Portable Sampler is a programmable liquid
sampler and is one of Teledyne Isco's 3700 Series of portable and
refrigerated samplers. The extensive sampling capabilities; easy,
flexible programming, and durable construction make the 3700
Series ideally suited for general-purpose or priority-pollutant
sampling. The 3700 samplers also provide storm-paced sampling
capabilities designed to meet the EPA requirements for storm
water runoff monitoring.
The 3700 Compact is a smaller version of the 3700 Standard. It
has the same sampling capabilities, flexible programming, and
rugged construction of the larger 3700s, but is lightweight. A new
feature of the 3700 Compact is a removable inner sleeve to hold
the bottles. Previously, users who wanted multiple-bottle configu-
rations had to purchase different bases; with the 3700 Compact,
they merely remove the inner sleeve and change bottle configura-
tions.
The entire 3700 family offers a number of very sophisticated fea-
tures. The following sections provide an overview of the standard
and compact units' sampling capabilities and a variety of inter-
facing equipment. The end of this chapter provides a brief dis-
cussion of this interfacing equipment, which includes:
• Teledyne Isco 4200 Series Flow Meters, 2100 Series
Flow Modules, and 4100 Series Flow Loggers (collec-
tively called "flow meters" throughout this manual) for
flow-paced sampling and sampler-enable control.
• Laptop computers that collect, store, or transfer the
same data from a sampler in the field to a computer in
the office.
The 3700 Standard is designed for operation in hostile environ-
ments, such as sanitary sewers, without additional protection.
The gray acrylonitrile-butadiene-styrene (ABS) plastic used in
the basic construction of the exterior exhibits good resistance to
aqueous solutions containing common acids and bases. All of the
other external components are made of either stainless steel,
anodized aluminum, polypropylene, Noryl, or EPDM.
The 3700 Standard consists of three units: the top cover, the
center section, and the base section. The removable cover pro-
tects the control box mounted on the center section. The center
section includes the control box, liquid detector, pump, and distri-
bution system.
