With the 3D Precision Test Gauges there is no need for preliminary pressure cycling. All materials used are selected to be corrosion resistant. All gauges are supplied with a bleed port, and Bronze bushings are used ensuring low friction and long term precision in extreme applications involving dust, vibration and temperature variation.
The gauge dial uses 3D instruments well known anti-glare soft green with mirror anti-parallax band, and white outer ring for maximum user resolution. This system has proven practical advantages for technicians and engineers.
All Precision Test Gauges dials are linear and interchangeable in the field for the same pressure range. The advantage of using the Ni-Span C Bourdon tube and the resulting low hysteresis is that the Precision Test Gauges are not individually matched to a non-linear dial. This makes field repair and calibration not only a possibility but a relatively easy task performed with exactness and facility by instrument technicians in real world situations.
3D Instruments, already the major force in mechanical field test gauge pressure instruments, is proud to supply the best available Precision Test Gauge for your high accuracy applications.

Precision Test Gauge Accuracy - 0.1% of span This accuracy statement includes repeatability, linearity and hysteresis, obtained by calibration with pressure standards traceable to N.I.S.T.
Calibration Points - 12 points up scale and 12 down scale
Overpressure - 120% of span without calibration shift 200% of span without damage
Repeatability - 0.02% of span
Hysteresis - .1% span or less
Measure Fluid - gauges are calibrated with air (up to 1,000 psi) or distilled water (up to 10,000 psi). Other fluids compatible with Ni Span C, 300 series stainless steel ad Buna-N may be used. Gauges may be oxygen cleaned.
Needle Movement - 310 degrees
Temperature - 25 degrees F (-32 degrees C) to 125 degrees F (+52 degrees C) operating ambient
Warranty - 5 years
The lowest full scale pressure is 15 psi ( 1bar ), the highest full scale pressure is 10,000 psi (660 bar) or the equivalent in other pressure units. These ranges are available in PSIG, PSIA, INCHES OF MERCURY, and MILLIMETERS OF MERCURY. Other ranges and pressure units are available on request.
