Stack Analog Gauges
Stack Stepper gauges (ST33xx) use precision stepper motors to move the needle both up and down. This gives very fast response time in both directions, with a rock-solid needle. The 270 degree sweep dial gives very accurate readings.
Stack Electric gauges (ST32xx) use a time-proven conventional air core movement for economy. The 90 degree sweep dial is quick and easy to read.
Stack Pro-Control gauges (ST35xx) combine stepper motor movement with advanced features like configurable alarms and outputs to run fans, pumps, or external alarms.
