8 INPUTS DATA LOGGER FOR THERMOCOUPLES
HD32.8.16
16 INPUTS DATA LOGGER FOR THERMOCOUPLES
Instruments HD32.8.8 and HD32.8.16 are two robust data loggers with 8 inputs the
fi rst, 16 inputs the second, for K, J, T, N, R, S, B and E type thermocouple with
miniature connector temperature probes.
• Unit of measurement °C, °F, °K confi gurable.
• Flash memory organized in 64 sections with a total capacity of 800.000 acquisitions
to be divided among all the present inputs. Storage can be managed in two ways:
- when the available memory is full, data are overwritten by starting from the oldest
ones (circular memory),
- storage stops when the available memory is full
• Simultaneous display of 4 inputs.
• Maximum, minimum or average of the stored values.
• Selectable storage interval: 2, 5, 10, 15, 30 seconds, 1, 2, 5, 10, 15, 20, 30 minutes
and 1 hour.
• Data logging: instantaneous or postponed, with the possibility of selecting the
storage start and end.
• Data download: RS232C, 1200...38400 baud or USB 1.1 – 2.0.
• Deltalog9 downloadable from Delta OHM website software for data download and
processing.
• LCD backlit graphic display 128x64 pixel.
• Instrument setup through the keyboard; no connection required to the PC.
• Security password for keyboard locking.
• Power supply: 4 1.5V alkaline C-BABY type batteries, or external power supply
12VDC-1A or by means of the USB port of the PC.
• Consumption @6VDC: <60μA when the instrument is off
<60μA in sleep mode with all the probes connected
<40mA during data logging with all the probes connected
• Use of data loggers HD32.8.8 and HD32.8.16: in fi eld for measurement campaigns
on complex systems with many measurement points, testing facilities, in
pharmaceutical and food sectors, ovens mapping, air conditioning centrals etc.
