Model PT-1 Pressure Tester
Brand: Ashcroft IncThe 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
