Personal Air Sampler (PCXR8KD)

Universal Pump PCXR8KD With its computer-controlled timer, the PCXR8 air sampling pump makes intermittent sampling a reality. Users can now extend the sampling time of chemicals with analytical methods that dictate low air volumes. By sampling intermittently over the desired period, air volume requirements are maintained and a true TWA is achieved. Users take fewer samples and save analytical costs.

To accomplish this, the user simply enters a sampling time which is greater than the pump run time. The computer then controls the on/off cycling of the pump so that the sample is taken intermittently over the desired sampling period. TWA tests ranging from 8 hours to 7 days in duration are possible, depending on the type of sample being collected.
The 224-PCXR8 offers unique "Short Interval On/Off" air sampling that gives average concentrations over extended periods: overnight, 24 hours, weekends, and up to one week—all at the press of a key.

Example: At 4 p.m. on Friday a week long Benzene TWA sample is desired, extending from noon Sunday until 8 a.m. the following Sunday. Set delayed start to 44 hours, pump period to 8 hours, and sample period for 6 days, 20 hours. The computer turns the pump on at noon Sunday with a 1-minute on, 19.5-minute off cycle and shuts down 6 days and 20 hours later.
Result: A true TWA sample for the entire week.
Computer Controlled PCXR8 Air Sampling Pump Meets the Challenge

::Indoor Air Quality::
Challenge: An employee complains about a chemical smell that makes him sick but the smell never occurs while the investigator is present.
Solution: Program the pump period to 480 minutes (8 hours) and the sample period for several days. This will allow unattended intermittent sampling and an opportunity to capture the chemical hazard of interest.

::Shiftwork::
Challenge: There is a need to monitor employees working the midnight shift, but health and safety professionals are not available at this time.
Solution: Before leaving the plant at 4 p.m., set the pump for a 480-minute (8-hour) delay start and a 480-minutes (8-hour) sample period. Leave the pump and appropriate instructions with the shift supervisor. The pump will turn on at midnight and shutdown at 8 a.m. All sampling times will be retained on the LCD.

::Personal or Area Sampling::
The result of extensive research and development, the PCXR8 is a constant flow air sampling pump suited for a broad range of applications. With an operating range of 1000 to 5000 ml/min (low flow applications of 5 to 500 ml/min require an optional adjustable low flow holder), this battery-operated air sampling pump is ideal for industrial hygiene studies as well as environmental testing. Specifically designed for on-worker and fenceline applications, the PCXR8 air sampling pump is typically used with collecting devices such as:

- Sorbent sample tubes and Long-duration detector tubes for collecting most hazardous chemical gases and vapors from the air
- Cyclones for collecting respirable dust
- IOM samplers for collecting inhalable dust
- Filters for collecting total dust, asbestos, or chemical hazards
- Tedlar sample bags for collecting airborne chemical hazards
- Impingers for collecting reactive chemicals into liquids

The PCXR8 on-board computer makes operation easy and permits unattended sampling for periods up to 7 days. In addition, the PCXR8 offers:

- Multiple-tube sampling capability
- Compensation with high back pressure
- Quiet-running package
- Wide range of flow rates
- Energy efficiency
- Programmable timing

The PCXR8 air sampling pump is so dependable, we guarantee its performance for a period of one year from date of purchase.
