The portable RDXL4SD and
RDXL12SD models are
handheld thermometer/data
loggers with backlight display
and built-in analysis functions.
The data loggers are powered
by an internal battery and are
capable of sampling,
processing and displaying
measurements without being
connected to a computer. With
their high resolution and fast
analog to digital converter
(ADC), the RDXL4SD and
RDXL12SD meet the majority
of data logging requirements in
most industrial applications.
Real-time SD memory card
data logger, built-in clock and
calendar, real time data
recorder, and sampling time
set from 1 to 3600 seconds
comes standard. Data logger
can log data manually by setting
the sampling time to zero. These
real-time data loggers, save the
4- or 12-channels temperature
