- Block touch screen display ( it is probably an android computer. it needs room to store the ram, hard drive, so on.) vs Mono-gameboy display or use of 3rd party Tablet from Amazon which I may add that you won't get support from Neptunes for it.
lets crunch some numbers:
- Cerebra with multibar which has all the ports you need and not separate modules and a smart temp probe that has light indicators - $374
We will add the basic probes everyone use. Not many actually use ORP so we will leave that out.
- Dual Junction pH probe - $62.99
-Conductivity Probe - $80.99
Total: $518.97 which is less than the Apex Classic ( $549.95) and you also have a conductivity probe.
Lets go a little further and say you want to add the ORP probe and want another energy bar which is the same as the New Apex:
ORP Probe: $71.99
Energy Bar: $149.99
Total: $740.95 (Still less than the New Apex $799.95 + you still have more room to add another pH probe without having to buy another module; Also you have 12 energy sockets to use.)
