Also, with a kit I would get complacent and not check it for long periods; with the probe I glance at it every morning and evening so if there is a problem I will be aware of it pretty quickly.

If you want to leave the probe in the water and the meter switched on all the time then you need to also purchase the small transformer to power it but I think that with all of these types of instrument (salinity probe etc) it's best to keep them away from constant exposure to salt and damp and just dip the probes at regular intervals to ensure that parameters in the tank are o'k.
