1084 Pocket Test Gauge (�0.5% of span)

With an accuracy of �0.5%, Grade 2A, plus rugged stainless steel construction, the Ashcroft� Type 1084 more than exceeds the requirements for on-the-spot inspections. To improve accuracy, stability and socket thread life, the Bourdon tube and socket assembly is made of type 316 stainless steel with all-welded construction; this system is standard for all ranges. To make reading easier and faster, each unit is provided with a new, highly readable dial. Reading error caused by parallax is eliminated by aligning the knife-edge tip pointer with its reflection in the mirror band on the dial. Also available is a stainless steel cover that fits securely over the window and protects the gauge from damage while being carried in a tool box or pocket. An attractive, cushioned Nylon fabric pouch with carrying strap is offered as standard equipment.

1082 Test Gauge (�0.25% of span)

The standard Ashcroft� test gauge case style features a solid-front aluminum case with a hinged ring. The dial has a polished mirror band for pointer reflection to prevent parallax error and is available in 4.5", 6" and 8.5" dial sizes in both lower and back connection. Pointer is a balanced-friction adjustable design with red knife edge tip for easy reading. The standard test gauge is competitively priced and available from stock for most ranges, tube materials and case sizes.

A4A Precision Dial Pressure Gauge

The Ashcroft� precision pressure gauge yields consistent, reliable accuracy through the use of state-of-the-art precision machining and the world�s most refined bourdon tube technology. This eliminates the need for a power source and precludes the associated problems such as susceptibility to electronic line noise, power outage or potential fire hazard. In addition, this mechanical instrument is simple to operate, easy to troubleshoot, and can be readily flushed or purged to remove foreign matter or trapped gas. Accurate and reliable, the Ashcroft A4A sets a new standard for precision test gauges.

1305D Deadweight Tester (�0.1% of reading)

Ashcroft^� Type 1305D deadweight testers provide an easy means of precisely generating pressure to an accuracy of 0.1% of reading. Ashcroft 1305D units are available for operating ranges up to 10,000 psi. They are ideal for use in calibrating, setting, testing and repairing pressure measurement and control devices. Each 1305D unit is traceable to the National Institute of Standards and Technology, assuring instrument accuracy. These pressure systems are designed to be field portable. A single carrying case holds the pressure generation pump as well as all the necessary tools and accessories. A second box contains the weights used for pressure generation (10,000 psi units require two boxes of weights). Ashcroft deadweight testers qualify as primary standards for pressure calibration. The pump is a two-stage hydraulic pressure generator. A built-in shuttle valve allows for rapid pressure increase at low pressures. The rate of increase per pump cycle can be reduced at higher pressures to minimize resistance. This is accomplished by simply repositioning the two-position shuttle valve. With the shuttle valve in the high-pressure position, increasing pressure even when near the 10,000 psi upper limit can be accomplished quickly and easily. Final, precise adjustment is accomplished through the use of an integral vernier-adjustment knob. The 1305D is provided with two-piston cylinder assemblies. A low-pressure piston for pressure ranges from 15 to 2000 psi and a high-pressure unit for pressures from 75 to 10,000 psi. The high-pressure piston has an area of 1/80th of a square inch while the low pressure piston has an area of 1/16th of a square inch. Weights are provided for pressure increments of 5, 10, 20, 25, 40, 50, 100, 200 and 500 psi (depending on piston in use). An optional 1 psi incremental weight is also available. Ashcroft 1305D testers can be used anywhere within their operational range without any change in accuracy. The same weights are used with both piston and cylinder assemblies. Ashcroft 1305 units are available for psi, bar, kg/cm² and kPa ranges. Each unit comes complete with a hand jack set (for removal of pointers on gauges being calibrated), spare O-rings and all tools, accessories and fittings required for normal use.

Pressure Gauge Comparator

Type 1327D, Accuracy (�0.25%)
Type 1327CM, Accuracy (�0.1%)

Ashcroft^� Types 1327D and 1327CM are designed to be field portable pressure generation and test systems. A single carrying case holds the pump used to generate pressure as well as the gauges selected as the test standard. Both units include an Ashcroft two-stage hydraulic pressure pump. A built-in shuttle valve allows for rapid pressure increase at low pressures. The rate of increase per pump cycle can be reduced at higher pressures in order to minimize resistance. This is accomplished by simply repositioning the two-position shuttle valve. With the shuttle valve in the high-pressure position, increasing pressure even when near 10,000 psi can be accomplished quickly and easily. Final adjustment is accomplished through the use of an integral vernier-adjustment knob.

The Ashcroft Type 1327CM is a precision gauge comparator which is provided with 6-inch Ashcroft �0.1% F.S. accuracy Type A4A gauges. The gauges provided include temperature compensation which maintains the �0.1% F.S. accuracy over an operating range of �25�F to +125�F. Available ranges include 30, 100, 500, 1000, 5000 and 10,000 psi.

The Ashcroft 1327D is available with between one and four Ashcroft gauges covering the operating range of 0 through 10,000 psi. Metric range models are also available.

The 1327DG is provided with 4.5" Ashcroft Type 1082 test gauges. These gauges provide an accuracy of �0.25% F.S. The Ashcroft test gauges include temperature compensation and have a maximum thermal error of 0.005% F.S. per degree F.

Ashcroft Types 1327CM and 1327D are ideally suited for use as in-field pressure standards. Both come with temperature-compensated gauges, further enhancing their field worthiness. A single carrying case holds everything needed to take full advantage of the capabilities of the test set. psi and metric ranges are available for either system. Both systems are traceable to NIST with the 1327CM provided with calibration certificates for each gauge selected.
