6712SR Refrigerated Sampler
Section 1 Introduction
1-3
sampler is equipped with the optional dial-out modem), or from a
581 Rapid Transfer Device (RTD). The RTD is a quick and simple
way to transfer the data from the field to your computer. Reports
are easily collected with Teledyne Isco’s Samplink software.
1.5 Pump Requirements The pump requires a pump tube made specifically for the 6712
and 6700 Series samplers. These pump tubes are easily recog-
nized by their blue alignment collars. The 6712 pump tubing is
the same as that for Teledyne Isco’s 6700 Series samplers, but
different from Teledyne Isco’s earlier model samplers, such as the
3700 Series. Other types of pump tubing will not work in
the 6712SR. Refer to Replacing the Pump Tube on page 8-8.
