Type ST-2A Digital Indicator FEATURES • Measurement of pressure, temperature, voltage and current • Accuracy ratings of ±0.1, 0.05% and 0.025% F.S. (pressure) • Pressure ranges from 0.25 inches of water to 10,000 psi • Interchangeable pressure and temperature modules • Multiple engineering units • Temperature measurement with most common RTDs and thermocouples • Programmable damping • Tare capability • Display hold • RS232 two-way communications • Standard N.I.S.T.-traceable certificate of calibration The ST-2A is the perfect bench companion product to the Ashcroft® ATE-100 field handheld calibrator. This bench top (or panel mounting) package shares the same pressure and temperature modules and interfaces with the same software packages as the Ashcroft ATE-100. An intuitive menu- driven user interface puts all of the ST-2A’s power at the simple press of a key. It uses the AQS (Ashcroft Quick-Select™) modular sensor system to provide the ultimate in measurement flexibility. Now you can purchase a calibration system to serve your field and bench mounting requirements while enjoying the significant cost savings gained through the availability of common pressure modules and software.
