Verdict: Sensible, good value option

Cons: Deltronics supply what most people need.

Future proofing: a long standing company that has developed a range of sensors and then updated its data loggers over the years. With only one range of sensors, Deltronics earns a high future-proof rating.

Deltronic's Extra Sense Interface plugs into your computer and your choice of sensors plug into this. Sensors to measure temperature, light, sound, time (light gates), speed of sound, position, and more are available. Although not a remote data logger, it will suit many classroom situations. The Deltronics remote data logger, called MiniSense uses the same sensor range as Extra Sense. The systems works with PC and Mac computers using Insight software and are very keenly priced. Versions for computers with USB ports (i.e. without a serial port) available.
