Vaetrix Gauge 4

Precision and Toughness For Field Testing

The new Vaetrix Gauge 4 Pressure Gauge from Taylor Valve Technology Inc. is designed for superior performance under tough field service conditions. From its reliable microprocessor-based technology to its rugged, lightweight case, the easy to handle Gauge 4 sets a new standard for performance, with its 5 full digits display and ¾" digits and floating decimal point and on board barometric pressure. Pressure accuracy of 0.1% of indicated reading (combined error for temp, linearity & hysteresis) on 5000-PSI units and below. Pressure accuracy of 0.05% Full Scale (combined error for temp, linearity & hysteresis) on gauges above 5000 PSI.

Thanks to the Gauge 4's straightforward design and common-sense display, even operators with little or no field operating experience achieve remarkable results the first time out. In fact, this pressure indicator is so well designed, it actually helps build operator confidence and ensure reliable testing results by eliminating the sources of many common operator errors. As a result, even first time users can acquire sophisticated readings with extreme accuracy.

Powered by 4 double A batteries, the Gauge 4 is designed to deliver up to 250 hours of continuous uninterrupted service.

Field-Proven Performance Features

Designed especially to deliver superior performance under tough working conditions, the Gauge 4 combines reliable microprocessor-based technology with rugged design to bring portable, precision electronic pressure measurement performance to field-testing. This means Gauge 4 operators can count on benefiting from high accurate pressure measurements.

Innovative Hardware & Software

The state of the art electronics and software inside the Gauge 4 are every bit as advanced as the lightweight and functional package they are housed within. For example, its built-in calibration and diagnostic programs make the Gauge 4 the most reliable instrument of its type in service today.

Internet service is also available for return for recalibration certification and repair of the instrument to maintain NIST certification and trace ability.
