110 VAC @ 60 Hz and 5 Amps. (50 Hz acceptable: must be set in software.)
Europe: Must use isolation transformer to step-down from 230 to 110 VAC. We recommend a Single Phase Type 1 Isolation Transformer from Radio Spares (Part no 260-4272 at www.rswww.com). A specific mains plug will be needed, Part no 235-9950.

• Helium: of at least 4.7 grade (99.997% pure.)
• Nitrogen: of at least 4.8 grade (99.998% pure.)
• Recommended size of tank is 300

Our recommendation is a single stage regulator for each gas tank with the following specs:

• Stainless steel diaphragm
• Helium leak integrity of 1 * 10^ (-9)
• Ultrasonically cleaned 1/4" NPT male or female outlet
• Recommended DART inlet pressure is 50-60 PSI, absolutely no less than 35 PSI.
• NOTE: A dual stage regulator will work fine, two stages just isn’t required. (Part no: SGD3101-100-580 from Specialty Gas Equipment Inc. www.sgd.com)

We recommend the use of a particulate filter on both N2 and He gas lines entering the DART Controller. This helps to ensure no foreign objects (particularly with in-house gas lines) contaminate or block gas flow through the DART. The filter should be placed after the regulator and before the DART Controller.

If customers wish to measure the flow rate of DART gas with an external meter, IonSense recommends the following:

• Dwyer Instruments Gas Flow Meter (www.dwyer-inst.com)
  Part No: RMA-22
  2-25 LPM Air
• Omega Digital Mass Flow Meter (www.omega.com)
  Part No: FMA1824
  0-20 SLPM N2 w/ Digital Display
  For Helium flow rate multiply flow value by He Gas K Factor equal to 1.454.
