I keep seeing the multitester advertised.... but there is nothing that tells you what is in the box.

Anyone out there know?

I also wonder at the costs of the interfaces.... probes, well I can appreciate that different sensors will have different prices, that is pretty obvious to anyone.

Buut, the interfaces themselves appears to be very simple voltage -> USB devices. Why the differing prices for these?. Or is it to distribute the cost of the actual sensors across sensor & probe price, as it would be simple enough to integrate the interfaces into the probes... . . even allowing for the lifetime of the probes.

Hi pateism,

when you buy the multitester you will receive a box with inside the multitester, it's power supply and the manual.

You can buy the modules and  probes you prefere, these are the same of the Aquatronica Controller.

If you like you can buy the 2 plugs power unit that can be controlled by the multitester probes.

Bye
