Eight-Channel Process Signal Data Logger
The SmartReader 7 is a versatile data logger that can monitor and record a variety
of different process signals including the popular 4-20mA and 0-5V. With its
seven input channels, the logger is ideal for monitoring (through commercially
available transducers) a wide variety of measurement parameters such as flow,
level, pressure, and much more. All process signals can be displayed in their own
engineering units using the simple equation editor in ACR’s TrendReader® 2 soft-
ware.

SmartReader 5
Three-Channel Temperature (Thermocouple) Data Logger
The SmartReader 5 data logger is ideal for those applications that require moni-
toring extremely high temperatures or monitoring temperatures over a wide range.
The logger has one internal channel for measuring ambient temperature and two
external channels for use with ACR thermocouple wire or any J, K, S or T type
thermo couple wire. One external channel is for a narrow range and the other
external channel is for a wider range.
FEATURES
• Three channels
• Monitor extremely
high temperatures
• Monitor temperature
over a wide range
• Use with a variety of
different thermo-
couple probes

FEATURES
• Eight channels
• Connect virtually
any device that has
an analog output
• Record a variety of
parameters (i.e.
flow, level, pressure,
etc.)
• Several different
models to choose
from
