Low-pressure self-regulating ball-type pneumatic deadweight tester — the de facto custody-transfer reference standard. Engineered for closed-cover field operation; 21 range models span inches of water column to 30 PSI (2 bar) across eight engineering-unit systems (PSI, g/cm², mbar, bar, kPa, inH2O, cmH2O, mmHg). ±0.050% rdg standard accuracy, ±0.015% rdg with full calibration option. NIST traceable. Configure pressure range, calibration data, pressure medium, and o-ring material to build your part number.
Bench-top hydraulic pressure comparator for routine comparison calibrations against a reference standard. Built-in hand-pump and four Monel-internal test gauges in a single unit. ±0.250% F.S. standard accuracy (to 5,000 PSI / 350 bar); ±0.500% F.S. on the 10,000 PSI / 700 bar models. Available with imperial PSI or metric (kg/cm² / kPa / bar) gauges. Configure unit system, NIST traceable certification, pressure medium, and o-ring material to build your part number.
Imperial dual-column, dual piston/cylinder hydraulic deadweight tester. Side-by-side columns enable comparative calibrations and differential measurements; each model ships with both a low-range and a high-range piston up to 15,000 PSI. ±0.100% standard accuracy (±0.025% optional), NIST traceable. Configure pressure range, calibration data, pressure medium, and o-ring material to build your part number.
Top-of-line imperial Type T hydraulic deadweight tester at ±0.015% reading accuracy. Dual-column configuration with two interchangeable pistons (low + high range) and a dedicated weight set per piston, so high-range and low-range work proceed without reconfiguration. NIST traceable, local gravity correction + calibration data included. Configure pressure range, pressure medium, and o-ring material to build your part number.
Imperial single-column, dual piston/cylinder hydraulic deadweight tester for pressure calibration up to 15,000 PSI. Each model ships with two interchangeable pistons — a low-range piston for fine resolution and a high-range piston for top-pressure work. ±0.100% standard accuracy (±0.025% optional), NIST traceable. Configure pressure range, calibration data, pressure medium, and o-ring material to build your part number.
Imperial single-column, single-piston/cylinder hydraulic deadweight tester for pressure calibration up to 15,000 PSI. ±0.100% standard accuracy (±0.025% optional), NIST traceable. Configure pressure range, calibration data, pressure medium, and o-ring material to build your part number.
Imperial single-column, single-piston/cylinder hydraulic deadweight tester at ±0.015% reading accuracy — the highest accuracy class in the M&G imperial Type T DWT line. NIST traceable, local gravity correction + calibration data included. Available in five pressure ranges from 500 PSI to 15,000 PSI. Configure pressure range, pressure medium, and o-ring material to build your part number.
Metric dual-column, dual piston/cylinder hydraulic deadweight tester. Side-by-side columns enable comparative calibrations and differential measurements. ±0.100% standard accuracy (±0.025% optional via calibration upgrade). NIST traceable. 9 range models across kg/cm², bar, and kPa unit systems. Configure pressure range, calibration data, pressure medium, and o-ring material to build your part number.
