Pressure/Vacuum Calibrators
For calibrating and testing absolute pressure/vacuum measurement devices, gauges and switches.
Model 3112
PORTABLE LIVE PRESSURE TESTER
- Compact, completely self-contained unit designed for calibrating and testing pressure gauges, transducers, pressure switches, and other pressure-sensitive instruments up to 2,000 psi with an accuracy of ±0.25% of full scale.
- Easily transported to remote locations—no external gas or power sources are required.
- A 65 to 250 VAC electrical tester is built into the Model 3112 for convenient pneumatic switch testing.
Model 3194-F
Portable Pneumatic Amplifier
- Boosts standard gas cylinder pressures up to 10,000 psig.
- Compact, easy-to-use, benchtop design for peforming high pressure calibration, proof testing, and other lab applications.
- Incorporates a pressure intensifier with a 10:1 ratio to boost pressure from an external gas cylinder.
Model 3461
PORTABLE PRESSURE CAL/TEST SYSTEM
- The system is totally mechanical and doesn’t require any source of electrical power. “Oxygen Clean” version also available.
- Capable of generating calibration pressures up to 10,000 psi with an accuracy of 0.1% of the full scale range.
- Self-contained torque measurement standards lab.
Model 3540
PORTABLE GAUGE TESTER
- Designed for calibrating pressure gauges, transducers, controllers, and other pressure-sensitive instruments up to 2,000 psi.
- Accurate to ±0.1% of gauge span including hysteresis error.
- Automatic transfer valve permits stepless measurements over the entire range of the system.
Model 3666
Automatic Pressure Calibration System
- Portable secondary standards laboratory.
- Accurate to ±0.1% of the indicated value (IV) from 5 to 10,000 psig.
- Fast, efficient testing and calibration of pressure gauges, vacuum gauges, switches, transmitters, transducers, and other pressure sensing devices.
Model 3689-A
Precision Pressure Standard System
- Ideal for calibration of dial pressure gauges and digital pressure measurement devices.
- Unmatched in the industry for its accuracy: ±0.025% IV (read.) or 0.001 psi, which ever is greater.
- Three measurement modes are available: absolute mode, gauge mode, and vacuum mode.
