HUNTINGTON BEACH, CA 92649, with all transportation charges prepaid. 3D INSTRUMENTS,
LLC. shall have no obligation or liability extending beyond that of repair or replacement as stated
above and without limitation of the foregoing shall have no obligation or liability to the purchaser for
any direct or consequential damages or loss of profits. Repaired gauges shall be warranted for the
unexpired portion of the original warranty only.
This warranty shall not apply to any product or part which has been subjected to use in excess of
applicable 3D INSTRUMENTS, LLC. specification, use in violation of any special conditions noted on
the pressure gauge, disassembly, misuse, negligence in handling or extensive testing, nor does it
apply to replacement of plugged or damaged bourdon coils resulting from chemical or media
contamination.
By acceptance of the 3D INSTRUMENTS, LLC. product the purchaser agrees that (1) the foregoing
express warranty of repair and replacement is the exclusive and only warranty to pass with such
product or part. (2) The purchaser has not relied on the skill or judgment of 3D INSTRUMENT, LLC.
in selecting any such product or part for any particular purpose or need of the purchaser. (3) THE
FOREGOING EXPRESS WARRANTY IS IN PLACE AND LIEU OF ALL IMPLIED WARRANTIES,
INCLUDING THOSE OR MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE, and
(4) retention or possession of the product or part by the original purchaser or its successors for five
(5) years after date of purchase by the original purchaser shall be construed as conclusive evidence
that all warranty obligations of 3D INSTRUMENTS, LLC. have been fulfilled and that 3D
INSTRUMENTS, LLC. is thereby relieved from all warranty obligations.

The Best Precision Test Gauge For Your High Accuracy Requirements
The 3D Precision Test Gauge is certified for industrial and laboratory pressure transfer
measurement in the U.S. and worldwide.
Incorporating 3D Instruments' well know expertise in test gauge design and application, the
Precision Test Gauge provides unsurpassed long-term accuracy. The dial face design
comes directly from 3D experience with the practical use of high resolution pressure
calibration in the laboratory and the field.

Utilizing a highly sensitive Ni-Span C Bourdon tube, the Precision Test Gauge is
virtually unaffected by temperature variations. This obsoletes the need for an expensive
add-on temperature compensation device. The Bourdon tube material offers a superior
spring rate varying only 0.02% from –25°F (-32°C) to +125°F (+52°C).
With the 3D Precision Test Gauge 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 Gauge 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.
