Vacuum Regulator is a solid-state mercury-free digital regulator designed for precise measurement and control for a range of laboratory vacuum applications. The Regulator is preset to control at 300mm below atmospheric pressure, ideal for viscous asphalt testing with Asphalt Institute, Cannon-Manning, and Modified Koppers vacuum viscometers.
The PT-62 Vacuum Regulator is equipped with an internal vacuum pump and doesn’t require an external vacuum source. Its vacuum range of 28–410mm Hg below atmospheric pressure, with an accuracy of ±0.5 mm Hg, is suited for highly viscous materials such as asphalt cement at 60°C (140°F) per ASTM D2171 specifications. The system is NIST certified and traceable. It also includes an integral vacuum trap on the front of the Regulator to prevent liquids from being pulled into the system and damaging the internal components.
Features:
- Optimal for viscous asphalt testing with Asphalt Institute, Cannon-Manning, and Modified Kopper's vacuum viscometers with preset control at 300mm below atmospheric pressure
- Ability to control from 28 to 140mm Hg below atmospheric pressure for other laboratory vacuum applications
- Accuracy of ±0.5 mm Hg
- NIST-certified and traceable
