RDXL4SD and RDXL12SD thermometer/data loggers are portables handheld models with
backlight display and built-in
analysis functions. The data loggers
are powered by internal batteries
and are capable of sampling,
processing and displaying
measurements without being
connected to a computer. With their
high resolution and fast analogue to
digital converter (ADC), the
RDXL4SD and RDXL12SD meet
the majority of data logging
requirements in most industrial
Real-time SD memory card data
logger, built-in clock and calendar,
real time data recorder. Auto
sampling time can be set from 1 to 3600
seconds. The user can also log data manually by
setting the sampling time to zero.
These real-time data loggers save
the 4- or 12-channels of measured temperature
data, along with the
time information (year, month,
date, minute, second) into the
SD memory card. Data can be subsequently downloaded to Excel for analysis.
The RDXL4SD has four thermocouple input channels or two Pt100 input channels. The display can be set to to show channels 1 to 4 simultaneously or T1, T2 and T1-T2
The RDXL12SD has twelve thermocouple input channels. The display can show measurements from up to 8 channels simultaneously. A push-button toggles the display to the remaining channels.
