The P3000 Series is the culmination of over 50 years experience in the production and design of primary pressure standards. With features designed to improve accuracy and performance, increase reliability and simplify operation these deadweight testers can be used to calibrate virtually any pressure sensing device, including transducers, transmitters, gauges or pressure switches.
Each instrument is supplied with a detachable lid which makes it neat, compact and easily portable.
The weight masses are stored in a high-quality case with a self locking mechanism to protect them during transit.
All units are provided with an accredited calibration report, weight mass details, M14 x 1.5, M20 X 1.5, 1/8 inch, 1/4 inch, 3/8 inch and 1/2 inch NPT and BSP female adaptors, operating fluid (where applicable) and spare seals.
The piston/cylinder assemblies are manufactured to the very highest standards and are provided standard with ISO/IEC 17025 accredited calibration reports.
