Product Highlights
- One-year measurement uncertainty is ± 0.02% of reading from 10% to 100% with one Q-RPT, and from 1% to 100% with two Q-RPTs
- Low torque variable volume allows for pressure generation up to 200 MPa (30,000 psi) with minimal physical effort
- Separate fine adjustment tool for maximum, superfine control resolution
- User defined resolution and ready limits enable user to optimize performance based on DUT specifications
- High pressure isolation valve and pressure relief valve protect the low pressure reference transducer from over pressure when high pressure reference transducer is active
- AutoRange feature optimizes measurement and safety features for the specific range of the instrument being calibrated
- Simple rezeroing while vented at atmospheric pressure
- Simple, objective pressure ready/not ready indicator with user adjustable criteria to ensure repeatable results among operators
- Not dependent on local gravity or ambient temperature
- Sets and reads any pressure value directly in any unit of measure, without moving weights
- Built-in priming system to fill system with test fluid and purge unwanted air to assure smooth operation
- Optional foot switch accessory allows hands-free data collection when running AutoTests
- Main Unit
- Liquid Fill Kit
- Power Supply with cord
- Set of Test Port Adapters
- Unit is shipped dry, to be filled by the customer
