For
over 150 years, Ashcroft® instruments have set the
standards for accuracy, quality, and dependability in
pressure and temperature measurement.With products to suit virtually any application, Ashcroft pressure gauges, temperature instruments, pressure and temperature switches, transducers and transmitters are specified and trusted around the world for the most demanding requirements. In chemical processing, oil refineries, power plants, pharmaceutical, food, and industrial equipment applications, the Ashcroft trademark is the industry standard for performance and reliability.
The Ashcroft™ trademark has represented quality and reliability in pressure and temperature instrumentation for over 100 years. The broad line of pressure and temperature gauges and switches is complemented by a full line of pressure transducers and test equipment. Along with more traditional technology, Ashcroft offers exclusive mechanical innovations such as Plus™, PowerFlex™ and FlutterGuard™ movement technology to combat process vibration. The new line of Ashcroft Digital Test gauges offer a Total Error Band specification unmatched in digital or analog gauge products. Whether traditional analog or state of the art electronic, Ashcroft provides the reliability our Process and General Industrial customers require.
Gauges/Thermometers
A pressure gauge is not simply just a pressure gauge. Ashcroft® commercial gauges are available with exclusive features found in no other gauges. Our patented PowerFlexTM movement is more shock resistant than conventional movement gauges. Our TrueZeroTM feature gives you accurate indication of zero pressure in your system and the benefit of increased safety and reduced manufacturing and replacement costs. Our FlutterGuardTM option reduces pointer flutter that makes our gauges easy to read and last longer.

Gas Temperature Regulators
Low Pressure Diaphragm Gauge
Series 1490, ASME B 40.1
Grade A (±2-1-2% of span)
* 2.5" and 3.5" dial size
* Glass-filled polysulfone case material, won't rust or dent
* Beryllium copper diaphragm
* Brass socket
* Wetted materials of beryllium copper, brass, polysulfone, and RTV silicone
* Exclusive autoclavable feature
The Ashcroft® Type 1490 low pressure diaphragm gauge is designed to measure pressure from 10 in.H2O to 15 psi, both positive and negative pressures. This gauge uses a very sensitive diaphragm capsule to measure low pressure and vacuum. The gauge is specifically designed for use whenever the pressure medium is a gas that is not corrosive to beryllium copper, brass, polysulfone and RTV silicone. The polysufone case is suitable for intermittent or continuous service on natural gas provided a .013" throttle plug is installed in the socket. Typical applications are, but not limited to, vacuum pumps, gas leak detectors, air compressors, air filters, gas burners, gas measurement, vacuum ovens, suction regulators, and respirators.
Commercial Pressure Gauge
Type 1005, ASME B 40.1
Grade B (±3-2-3% of span)
* Case material is black-painted steel
* These gauges have a heat-resistant push-in polycarbonate window
* Dial faces match other Ashcroft® commercial gauges for easy readability
* Patented PowerFlexTM movement with polyester segment
* True ZeroTM indication, a unique safety feature
Ashcroft® Type 1005 gauges are available in 1.5" through 3.5" dial sizes. The full-view polycarbonate push-in window allows for better dial visibility. These gauges are commonly used on compressors, filter regulators, water pumps, beverage-dispensing equipment, paint sprayers and a variety of other applications.
Ashcroft Type 1005 gauges have the patented PowerFlexTM movement with polyester segment for increased resistance to rough usage, for a more durable, longer-lasting gauge.
True ZeroTM indication reduces the potential risk of installing a damaged gauge on your equipment.
FlutterGuardTM can be added to Type 1005 gauges to eliminate pointer flutter and extend gauge life.
Duratran Transmitters
Duratran® Transmitter
Type 2279, ASME B 40.1
Grade 2A (±0.5% of span)
Duratran® Transmitter/Gauge, takes the place of an electronic transmitter and a mechanical gauge
FM approved to 10,000 psi
4-20mA, 2 wire output
Zero and span adjustments
4.5" solid-front phenolic case
Accuracy: ±0.5% full scale including linearity, hysteresis, and repeatability
New Duratran® PLUS!TM Option:
Liquid-filled performance in a dry gauge
Fights vibration and pulsations without liquid-filled headaches
Order as option XLL - The result is reliable, local, analog pressure indication with an economical transmitter. . . A niche solution for any facility. The Duratran® solution is a reliable Duragauge® pressure gauge fitted with optical circuitry to provide a 4-20mA output. The 4.5" phenolic case is hermetically sealed, chemical and heat resistant. The wide selection of system materials and corrosion-proof housing meets a variety of demanding applications. . . even those with vibration and pulsation. This transmitter/gauge allows you to save money, replacing two instruments with one Duratran.
