The SS400 use an hp designed board. It is simpler internally and just streams the data as it comes in. The SS410 uses a board that was made by the probe company.
-can stream data rates independently (each probe sends as fast as it samples)
-can detect when a probe is removed during streaming
-higher sample rate (up to 40-50K or so IIRC)
-ocassionally can mis-identify a probe
-Internal NiCd pack, USB recharging
-nearly always identified probes correctly
-speed of sampling determined by slowest probe, all probes send at same rate
-slower sample rate (22-35K or so)
-doesn't notify on probe removal while streaming
Neither of these will work well for any long term monitoring things though. Not really designed for that sort of thing.
These really are faboulous little tools for doing classroom experiments. The only setup consists of "plug it in" and press START. Every teacher that ever sees this is very excited about the ease of use and power. The TI solution is really a huge pain to use and the vast majority of teachers report they waste so much time trying to get it to work properly that they just give up and never use it.
It is also quite capable. I debugged the serial port of the 10bII+ during development using a SS400 and a voltmeter. Turned on the oscilloscope mode, set it to trigger on rising edges, and was able to track down what was happening there. :-)
