Flow Fault

If pump is unable to compensate for longer than 15 seconds due to excessive back pressure, the pump enters flow fault. During flow fault, the pump stops, the fault icon appears on the display, and elapsed time remains on the display. Auto-restart is attempted up to 5 times. Elapsed time information will be lost on restart.

Low Battery Fault LCD displays low battery icon and pump shuts down. LCD remains on.

LCD Time Display LCD display shows elapsed pump run time in minutes up to 99,999.

LCD Indicator LCD always remains on. Displayed elapsed run time information resets when pump is started.

Ordering Info AirChek 52 Low Flow Capabilities
The full range of flow rates is available in one lightweight, low-cost, heavy-duty sampler. The AirChek 52 Air Sampling Pump becomes a fully versatile sampler when combined with the low flow Constant Pressure Controller (CPC) (Cat. No. 226-26-CPC) accessory. The CPC permits sampling in the 5 to 500 ml/min range.

AirChek 52 Air Sampling Pump with CPC Unit n Tube Train

AirChek 52 Air Sampling Pump with CPC
Simple to use, the CPC fits into the sampling train tubing allowing the pump to operate in a constant pressure mode. In the low flow mode, an adjustable low flow tube holder can be used to collect up to four tube samples simultaneously and at different flow rates. The flow rate at each intake of the adjustable low flow tube holders can be set from 5 to 500 ml/min (dependant on back pressure). Multiple-tube sampling reduces time in the field and uses fewer pumps.

Lightweight, Durable
Measuring approximately 5 x 3 x 1.75 inches (12.7 x 7.6 x 4.4 cm) and weighing only 20 ounces (567 grams), the small size, lightweight, and durable construction allows the AirChek 52 to withstand the rigors of on-worker use time and time again. Rechargeable NiMH or NiCad batteries provide a reliable power source which can be restored overnight. The AirChek 52 is the lightweight, inexpensive workhorse pump designed for rugged and repeated use. Now the full range of flow rates is available in one lightweight, low-cost, heavy-duty sampler to use with:

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
Impingers for collecting reactive chemicals into liquids
