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
measuring data, along with the
time information (year, month,
date, minute, second) into the SD
memory card and can down load
to Excel. The end user can make
any data or graphic analysis by
themselves.
RDXL4SD with 4 Type K
thermocouples and 2GB
SD memory card (included).
