6700SR Refrigerated Sampler
1
Chapter 1 Introduction
The 6700SR Refrigerated Sampler is an integral part of Isco’s com-
prehensive sampling system. The system includes the 6700SR Re-
frigerated Sampler, the 6700 Compact Sampler, and the 6700
Standard Sampler.
The 6700SR is ideally suited for permanent installation in a wide
variety of indoor and outdoor environments. The 6700SR is con-
structed from durable, corrosion resistant materials.
The 6700SR, with a variety of bottle kits available, is easily con-
verted both for sequential and composite sampling. Like all sam-
plers in the 6700 Series, it is compatible with a wide variety of Isco
instruments.
About 700 Series Modules
The bay on the controller’s right side accepts any of Isco’s 700 Se-
ries Modules. The 700 Series include:
• 701 pH Parameter Module for monitoring pH and temperature.
• 710 Ultrasonic Module for monitoring a flow stream’s level and
flow rate with an ultrasonic level sensor.
• 720 Submerged Probe Module for monitoring a flow stream’s
level and flow rate with a submerged probe.
• 730 Bubbler Module for monitoring a flow stream’s level and
flow rate with a bubbler system.
• 750 Area Velocity Module for monitoring a flow stream’s level,
velocity, and flow rate.
• 780 4-20mA Input Module for interfacing to non-Isco devices
with 4 to 20 milliampere output signals.
The modules are optional accessories. The samplers do not require
them for operation. However, the modules offer a number of advan-
tages. First, they are an economical way to combine flow rate or pH
monitoring with sampling. Second you can program the samplers
and modules as a single unit. Finally, the samplers store the mod-
ule’s level, flow rate, pH, or temperature readings in memory.
About YSI Sondes
The sampler accepts the optional YSI 600 Sonde to monitor four liq-
uid parameters: temperature, pH, dissolved oxygen, and conductiv-
ity. Conductivity readings can represent specific conductance, total
dissolved solids, salinity, or conductivity. You program the sampler
and YSI 600 Sonde as a single unit to combine parameter monitor-
ing with your sampling program.
The 6700SR also can support the YSI 6820 and YSI 600XL sondes.

Memory to Store Data
The samplers contain enough memory to store five sampling pro-
grams, sampling data, Isco 700 Series Module readings, and YSI
parameter readings. You can view the readings on your sampler’s
display, or print data reports with Isco’s 3770 Field Printer.
