DO9847K Three channel multifunction data logger for Temperature, Relative Humidity and
Temperature
measurement. Sampling speed one per second each channel.
Storage capacity 32000 samples per channel.
Functions: CLOCK, HOLD, RELATIVE , MINIMUM, MAXIMUM, MEAN MEASUREMENT.
Simultaneous display of the measurements on three channels or two channels plus the difference between
two channels. Calibration of the individual probes with permanent storage of the
calibration data inside the
probe, it is possible to change the probes without losing the calibration.

DO9847 | DO 9847 Three channel Portable Multifunction Data Logger |
The instrument allows the input of various types of probe of different physical magnitudes.
The software can be updated via RS232C, to implement new physical magnitudes, starting
from version 2.0.
Platinum probes (25, 100, 500 Ω at 0 C), Thermocouples K, J, E, T, N, R, S, B probes,
combined R.H. and
temperature, pressure also barometric one, air speed, light, mV and mA probes
can be connected through
the SICRAM modules.
Centesimal temperature measurements can be carried out by PRT sensors in the
range: 200 +350 C, and decimal in the range +350 +850 C.
Storage capacity: 32.000 readings per input.
Storage interval and printing can be confi gured between one
second and 1 hour.
RS232C serial output: from 300 up to 115.200 baud rate.
