Free Shipping on Orders Over $364.29 USD

The Ashcroft® PT-1 bench-top calibrator is used on measurement applications requiring highly accurate secondary transfer standards.

The PT-1 includes 1 or 2 permanently installed pressure or temperature sensors.
Features
  • Simultaneously display the output of two pressure sensors, two RTD’s or one of each
  • 12 standard user selectable engineering units and one custom value
  • Dedicated front panel buttons to set zero, check maximum/minimum values, adjust measurement damping, select either or both ports for standard display, additive or differential display, print the display and configure the RS232 output
  • All front panel features are accessible via the RS232 port for remote configuration or data acquisition
