Ensure that all of these accessories have been included with the instrument. If any
items are missing or damaged, contact Photovac immediately.
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).
4. If compound threshold limit values (TLVs) are exceeded, you should use
a gas bag for sampling and calibration.
To determine the TLV of the compounds contained in the calibration gas,
refer to the Material Safety Data Sheet (MSDS) supplied with your
calibration gas cylinder.
If you will be using a gas bag for calibration, see Calibration Using a
Gas Bag on page 63 for instructions.
Field Operation
For field operation, the 2020PROPlus Field Kit (Part No. MX750080) is available.
The field kit includes a cable kit, a carrying case and a calibration regulator, and a
spare battery pack.
Refer to the check list in on page 66 to ensure you have all the necessary accessories
and equipment before beginning field operation.
