DO9847 is a portable, multifunctional instrument and datalogger.
It has a 128×64 pixel (56×38 mm) graphic display and three independent inputs. Each input can be connected to one channel or two channel dual probes (e.g. two thermocouples, relative humidity/temperature, etc.). It automatically recognises SICRAM probes (configurable intelligent probe with memory) inserted at the inputs.
It is designed for input of Platinum probes, (25, 100, 500 Ω at 0 °C), Thermocouples K, J, E, T, N, R, S, B, combined relative humidity and temperature probes, pressure also barometric, air speed, light, mV and mA.
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
