Ashcroft ST-2A Pressure, Temperature, Voltage, & Current Indicator
The ST-2A is the perfect bench com-panion product to the Ashcroft® ATE-100 fi eld 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.

Temperature Interface Modules
AQS (Ashcroft Quick-Select) modules offer the ultimate in “plug-and-play” flexibility. They can be inserted and removed at the push of a button. The ST-2A automatically recognizes the sensor with no need for adjustments.
The AQS-1 pressure module provides ultralow pressure measurement solutions from 0/0.25 inches of water to 0/200 inches of water in gauge, compound and differential. They are designed for clean dry gas service and are durable with up to 1440 inches of water (50 psi) overpressure capability.
The AQS-2 pressure module provides ranges from 5 to 10,000 psi in gauge, vacuum, absolute and compound with 316SS isolation for severe media service available.
The AQS-RT temperature module provides an interface for 2, 3, and 4 wire RTDs. It is factory programmed with standard curves to support Pt100 (385 and 392), Ni 120, Cu 10. Another module supports Pt1000 temperature probes. Both can be programmed to support eight RTD curves.
The AQS-TC1 thermocouple interface module allows the ST-2A to measure temperature with types J, K, T, E, R, S, B and N thermocouples and includes an automatic reference junction.
