The working kit
The gauge your livelihood rides on
A tester's kit is a calibrated instrument, not a tool. Most jurisdictions expect documented gauge accuracy, so budget for the calibration habit, not just the purchase. Confirm what your water authority's test procedures require before choosing 3-valve or 5-valve.
