Support Equipment and Consumables

Calibration

For normal operation these items are required:

1. Calibration Gas Regulator (Part No. MX350006).

2. Calibration gas containing 100 ppm isobutylene (Part No. MX350012).

Other concentrations of the calibration gas may be required. This will
depend on your application.

3. Zero air (clean dry air without any organic impurities)

There are several alternatives for clean or zero air calibration: you can
use a bottle of clean air (certified as having not more than 0.1 ppm total
hydrocarbons) connected directly to the instrument; the clean air can be
transferred to a Tedlar bag which can then be connected to the
instrument; clean, ambient air without detectable contamination; or,
ambient air run through the charcoal filter (F1760160).

If you will be using large tanks of gas, specify a single stage, high purity
regulator with a CGA 590 connection at the inlet. The regulator should
also have a 1/8” parallel, compression fitting with which to connect the
regulator to the gas bag adapter. The delivery pressure must be
adjustable to between 5 psig (34.5 kPa). You may require a gas bag and
gas bag adapter (Part No. MX380014).

If you will be using a gas bag for calibration, see Calibration Using
Accessory Gas Bag on

page 67

for instructions.

Field Operation

For field operation, the 2020ComboPRO Field Kit (Part No. MX750080) is
available. The field kit includes a carrying case, a computer cable kit, a calibration
regulator, a spare battery pack, and a ProComm software CD.

Refer to the check list in on

page 71

to ensure you have all the necessary accessories

and equipment before beginning field operation.

Computer

The 2020ComboPRO may also be connected to a computer. The computer must be a
Windows

-based PC. Use the cable kit (Part No. MX750120) to connect the

2020ComboPRO to the computer.

NOTE: The 2020ComboPRO is not classified for use in hazardous locations when

connected to a computer
