Model 370 Digital Pressure Gauge
Brand: Setra Systems, IncSetra Systems Model 370 offers extremely high accuracy and unmatched stability in a digital output configuration.
Environmental monitoring and test and measurement systems around the world rely on Setra’s experience in barometric pressure measurement instrumentation, as well as high accuracy measurements of higher pressures.
The 370 utilizes Setra’s unique SETRACERAM sensor, which is combined with advanced microprocessor based circuitry and sophisticated firmware to provide system accuracy to better than ±0.02% Full Scale.
The Model 370 Digital Pressure Gauge is an extremely versatile instrument. Pressure and altitude data is displayed on a 6 digit LCD and is also accessible through a bidirectional RS-232 port.
A numeric keypad is provided for easy access to engineering unit conversions, minimum/maximum tracking, entry of High/Low alarm setpoints and calibration procedures.
The 370 is also available with an optional rechargeable battery pack to bring lab accuracy to the field.
