Pneumatic Calibration Test Pumps

  • DCAP Pressure Test Pumps - Hand Operated used to generate pressure up to 650 psi ( Pictured to the left)

  • Pnuematic Calibration Test Pumps- Generate vacuum and pressure with ease and precision (Varying pressure generation dependent on pump model number)

  • Pneumatic and Vaccum Cylinder Hand Pumps

Compressed Gas Control

  • Ralston Nitro-Pack - Proprietary pressure balanced fine adjustment piston allows for extremely precise, finger-tip control of pressure at 0.03 psi (2 mbar) or 3000 psi (210 bar) or any range in between

  • Ralston Compressed Gas Volume Controller - Perform accurate high pressure static calibrations or low-pressure differential caliibration.

  • Ralston Calibration Manifold - Perform Static pressure calibrations. Fine Control a compressed device, irrespective of the device being controlled

Quick-Test Hoses

  • Ralston Hose can be attached and detached without a wrench or thread sealant while maintaining a working pressure of 6900 psi or 10,000 psi.

  • Small in diameter, flexible, and low in volume

  • Ideal way of transmitting pressure during a vacuum or pressure calibration

  • 2ft - 100ft house with either Brass or Stainless Steel Connectors

Valves, Verniers & Valved Test Point Fittings

  • Block& Bleed Valves - Keep a calibration system pressurized with a fluid or gas while venting the pressure from the device being calibrated

  • In-Line Vent Vales - Slowly or quickly bleed pressure from a line after a calibration is complete

  • In-line Verniers - Connect one end to a Quick-test hose and the other to the process connection then turn the knob to control the pressure

  • Valved Fiitings - Install between a pressure gauge and the process and isolate the process from the gauge to perform a calibration of the gauge

Hydraulic Hand Pumps

  • Hydraulic Hand Pump - QTHP-0000 5Kpsi Hand Pump

  • Process Connection: 1/4" male NPT x male Quick-test, no check-valve, brass

  • XTHP-0000 10kpsi Hand Pump

  • Hose: Quick-test XT 10,000 psi hose, S.S. hose ends, 3ft long
