Ion slective electrodes and meters for determining water hardness do indeed
exist.  One source is Thomas Scientific(609) 467-2000.  They have a number
of regional toll free numbers.  The cost of the ion selective electrode for
water hardness is $395 and the various meters to which the electrode is hooked
run about $950.  pH electrodes run about $85 and can be used on the same 
meter.
