PK ll Series - Deadweight tester

Product catalog summary

Accuracy and Repeatability
The PKII Pneumatic Deadweight Tester offers accuracy options of ±0.015%, ±0.025%, or ±0.05% of reading, with repeatability at ±0.005% of reading. The temperature coefficient is ±0.00167% of reading per °C outside of 23°C. Accuracy varies below 10 inH2O.

Weight Masses and Pressure Range
The pressure range is from 0.145 to 30 psi or 1 to 200 kPa, with gravity set at 9.80655 m/s². Units available include psi, g/cm², mbar, bar, inH₂O, cmH₂O, and mmHg. Water column references are set at 20°C or 60°F.

Pressure Source
The tester uses nitrogen or instrument/shop air, with a maximum supply pressure of 100 psi and a minimum of 30 psi. Flow rates vary with output pressure.

Enclosure and Dimensions
Small case dimensions are 15 x 10.5 x 7 inches, while large cases are 15 x 14.5 x 9 inches. The weight can reach up to 28 lb.

Material and Connection
Weight masses are made of stainless steel, with aluminum for small increments. Connections are 1/4" Female NPT with an adapter for 1/4 tube fitting.

Models, Specifications, and Options
Various models are available with different certified ranges and increments. Calibration and accuracy options include standard or local gravity specifications.

Ordering Information
Sample part numbers are provided, detailing accuracy and range specifications.

Standard Delivery and Accessories
The standard delivery includes a tester base, weight set, manual, NIST traceable certificate, and additional accessories like a tripod and conversion weight sets.

Complementary Products
AMETEK offers additional products such as fittings, high-pressure hoses, digital test gauges, reference recorders, and pressure calibrators to complement the PKII tester.
