W & B Instruments has released the HD207/HD227 series of mini data loggers by Delta Ohm in Australia.
Delta Ohm designed the loggers to be a simple, rugged, accurate and extremely versatile temperature and humidity logging and recording solution at a low cost.
The product is suited to a variety of applications, including food storage and transport as well as laboratory, pharmaceutical and general manufacturing.

The internal temperature probe and remote temperature probe version has an IP67 protection rating, that offers protection against total immersion.
The range boasts models with and without readout display, and all models feature a total memory of 240,000 readings with a selectable logging interval of one second to one hour.

All the units use 'flash' memory, that is protected from loss or erasure even when a units has had its battery removed.
The user-friendly Windows-based DATALOG software enables storage and graphing of the readings together with alarm set points and alarm history. A standard feature of all models is the PC downloading interface cable.
