Specifications:
Accuracy and Resolution: Voltage measurement accuracy 0.1%, resolution better than 1 part in 50,000, depending on magnitude of input signal
Analog Outputs: Multi-range, 12 bit resolution, 0-5V output
Channels: Four, totally independent, assignable to oxygen or other gases depending on sensors used with the unit (oxygen is the default), range 0.1 to 100% in 0.1% steps, or off
Control Type: PID (Proportional Integral Derivative). PID settings adjustable by user
Gas Switchers: High speed electrical valves. Maximum applied pressure 25 p.s.i. (170 kPa)
Input Gain Setting: 1 - 1,000, fully automatic
Input Sensors: For oxygen, either (a) Sable Systems fuel cell sensor supplied with unit or (b) any user-supplied oxygen analyzers or oxygen sensors. For other variables, such as CO2, water vapor etc., any user-supplied analyzer or sensor
Operating Temperature: 0-50 C, relative humidity non-condensing
Power Requirements:12VDC nominal at 500 mA, Universal (90-240 VAC) adapter supplied
Pressure sensors: Two, range 0-200 kPa, accuracy 1% (can be user-calibrated to greater accuracy if desired).
Serial I/O: RS-232 serial, 115200 baud. Unit can output a text string containing setpoints, readings, and gas pressures at user-settable interval (1 - 500 sec), or it can operate in polled mode for full remote control (open protocol; program supplied)
Size/ Weight::8" x 5" x 12"; 5 lb (3 kg)
User Interface: Intuitive menu system backed by nonvolatile memory of user settings
