Ashcroft A4A Precision Pressure Gauge
Process Pressure Gauges – Ashcroft are the leading pressure and temperature instrumentation manufacturer of pressure gauges, test gauges and temperature gauges.
Ashcroft A4A precision pressure gauge is used throughout process and industrial markets globally and is known for it’s reliability, performance and safety. The Ashcroft A4A precision pressure gauge has been designed to be suitable for test, calibration and validation systems.
Ashcroft A4A Precision Pressure Gauge – Applications
- Test Laboratories
- Precision Test and Measurement Validation
- Calibration Laboratories
The Ashcroft A4A precision pressure gauge should ideally be used in temperatures ranging from –30 to +65°C and at very low temperatures standard pressure gauges may display slow pointer response times.
Ashcroft A4A Precision Pressure Gauge – Features
- Mirror-band dial and knife-edge pointer eliminates paralax error while assuring easy readability of precise measurements
- Solid-front case design and blow-out safety back protect users from
extreme overpressure - Optional Slotted link – protects gauge from sudden decrease in pressure
- Optional Thermal Compensation – to maintain accuracy over a wide
temperature range from -25° to +125°F
