DO9847 multifunctional handheld data logger

It is provided with a 128x64 pixel (56x38 mm) graphic display and three

Independent inputs. Each input can be connected to one channel or two channel

dual probes (ex. two thermocouples, relative humidity/temperature, etc.).

The instrument automatically acknowledges SICRAM probes connected to the

input (memory equipped and configurable intelligent probe). Functions: watch, hold, max., min., average, record, immediate or deferred start

record logging, difference between the two inputs, relative measures, three input

channel measurement and inside reference temperature display. Sampling time: one per second/input.

Probe calibration through SICRAM module; calibration data permanent storage

inside the probe. Storage capacity: 32.000 readings per input.

Storage interval and printing can be configured between one second and 1 hour.

RS232C serial output: from 300 up to 115.200 baud rate.

Immediate or deferred print-out.

Stored data can be displayed and stored data blocks can be deleted.

Automatic shutout after 8 minutes can be disabled.

Units of measurement can be selected according to the physical quantity of the

connected probe.

Firmware update through RS232C serial port. Different types of SICRAM modules or probes can be connected to the input: Platinum sensor temperature, thermocouple, relative humidity/temperature, Discomfort index, continuous voltage

(±20V), current (0…24mA), pressure, air speed and light.
