The AMETEK HydraLite HLG Gauge is a precision, portable instrument used to accurately measure pressure in field conditions. The HydraLite HLG gauge may be used as a primary standard instrument where a high accuracy reference measurement is needed. Simply connect the gauge to the process and add weights until there is a proper float. Standard accuracy is ±0.1% of indicated pressure traceable to the U.S. National Institute of Standards and Technology (NIST). The instrument may also be specified with +0.05% accuracy.
If you initially need a gauge and later find that you need a full tester, an accessory kit is available to incorporate the screwpump into the gauge.
