Gauges are the life blood for anyone in the flow test industry.  Our glycerin filled pressure gauges measure PSI in different increments depending on the job. We also carry gauges that read BOTH PSI and GPM as well as digital gauges, which, we can confidently say, are the most accurate field gauge currently available.

*NEVER hand twist a gauge into a fitting. This turns and misaligns the movement inside the case, ruining any chance of calibrating. Always use the proper wrench and do not overtighten.
