Multi-function data logger

The Delta Ohm DO9847K multi-function high accuracy data logger uses SICRAM modules (which allow calibration data of the sensor to be stored in a non-volatile memory) connected to the sensor. Modules are available for RTD, thermocouples (K, J, T, E, R, S, B, N), combined temperature and relative humidity, ±20 V DC, 0-24 mA DC, pyranometers and albedometers (solar radiation measurements).

The DO9847K is a 3 channel unit with a storage capacity of 32,000 per channel (in 16 data files) and depending on the type of input can measure and log up to six variables simultaneously.

Depending on input type resolution is from 0.1°C and accuracy from ±0.03°C (excluding sensor errors). Features include: direct printout (without PC), downloading to PC via HyperTerminal, 56 x 38 mm graphic LCD, operation from 4 AA batteries or plug pack AC adapter, internal temperature display, real-time clock with logging from 1 s to 1 h and updateable firmware via the serial port.

Measurement and logging modes include: watch, hold, maximum, minimum, average, differential and relative measurements with immediate or deferred start logging. A large variety of standard RTD, thermocouples and combined temperature and humidity probes are available. Custom made temperature sensors are also available.
