W & B Instruments has announced the release of the Delta Ohm DO9847K multi-function high accuracy data logger.
The DO9847K utilises 'SICRAM' modules (which allows 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), combine temperature and Rh, (20V dc, 0-24mA 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 0.01°C and accuracy from 0.03°C (excluding sensor errors).
Features include: direct print out (without PC), downloading to PC via HyperTerminal, 56 X 38mm graphic LCD, operation from four AA batteries or plug pack ac adapter, internal temperature display, real time clock with logging from one second to one hour and updateable firmware via the serial port.
Measurement and logging modes include: watch, hold, max, min, average, differential and relative measurements with immediate or deferred start logging.
A large variety of standard RTD, thermocouple and combine temperature and humidity probes are available from stock and customer made temperature sensors are also avaliable.
The DO9847K is supplied complete with interface cable and carry case and is supported by a full 2 year warranty.
