For the cost involved in this, it is more than just a simple "test kit upgrade". I think you may be able to find a better use for the funds if this is just for hobby testing. For instance, model DR/980 is the most feature rich device they offer testing for 32 different parameters at a cost of about $1000. While testing for 32 different parameters for a thousand bucks sounds good, would you also need to purchase 32 different reagents separately at a cost of $20-$30 per reagent, meaning an extra $640-$960(although saltwater aquaria does not require every one)? Would you still need to buy replacement probes? $$$$!! On the other hand, for lab grade testing, this sounds like it may be a more economical alternative when compared to other "lab grade" test.
