THE Delta Ohm model DO2003, available from W&B Instruments , is a versatile portable instrument capable of logging air speed and flow, temperature and relative humidity, differential and atmospheric pressure readings, specifically designed for the heating, ventilating, air conditioning and environmental applications.
The datalogger will store up to 12,000 readings, all of which are date stamped by the internal real time clock. Logging interval can be from one second to one hour and the unit is fully programmable from the front keypad without the need for a PC.
Stored readings can be printed out directly by use of an optional serial interface printer or downloaded to a PC using the graphical software included.
Other features include maximum, minimum and averaging measurement modes, measurement unit selection, stored data protected from loss and wide operating range with high accuracy.
The DO2003 datalogger will accept a wide variety of sensors including: hot-wire probes, vane probes, Pitot tube probes, pressure probes (barometric and differential), Pt100 and thermocouple temperature probes and combined relative humidity and Pt100 temperature probes.
