ST-2A Digital Indicator
Brand: Ashcroft IncThe Ashcroft® ST-2A bench top (or panel mounting) calibrator shares the same pressure and temperature modules and interfaces as the Ashcroft ATE-100.
It uses the AQS modular sensor system to provide the ultimate in measurement flexibility.
The base unit contains a wide variety of application-specific firmware as well as the ability to measure both current and voltage inputs.
In addition, this unit has the ability to interface the system with a computer, data acquisition system or dumb terminal via the standard RS232 interface.
Features- Measurement of pressure, temperature, voltage and current
- Accuracy ratings of ±0.1%, 0.05% and 0.025% full scale (pressure)
- Pressure ranges from 0.25 inches of water to psi 10,000 (kPa: 68,950, bar: 689.5)
- Interchangeable pressure and temperature modules
- Multiple engineering units
- Temperature measurement with most common RTDs and thermocouples
- Programmable damping
