Features

Flow range of 1000 to 3000 ml/min
Ideal for most personal sampling applications including sorbent tubes, filter cassettes, impingers, and size-selective samplers, and long-duration detector tubes; high flow range of 1000 to 3000 ml/min; low flow range of 5 to 500 ml/min requires low flow accessories
Constant flow compensation
Provides constant flow within ± 5% for accurate air volumes
For both high and low flow applications
Eliminates the need for separate sampling pumps for high and low ranges when using the optional Constant Pressure Controller (Cat. No. 224-26-CPC) and Adjustable Low Flow Holder (Cat. No. 224-26 series)
Minimum controls for easy operation
Two pumps in one easy-to-use sampler
RFI/EMI shielded and UL Listed for intrinsic safety
Case material and unique circuitry are designed to provide shielding from radio frequencies in the range of 27 to 1000 MHz, UL Listed for intrinsic safety for Class I, Division 1 and 2, Groups A, B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III, Temperature Code T3C; CE marked; ATEX-approved model available
