Accurately audit outdoor PM air samplers

Audit PM10 and PM2.5 air samplers in any weather. Cold weather, humidity and wind gusts all wreak havoc on a technician’s ability to accurately audit outdoor PM air samplers. Alicat’s FP-25BT mounts directly to the FRM or FEM air sampler to negate the effects of wind gusts, and its internal sensors are accurate from -30°C to +60°C and 0-100% RH. Its weatherproof construction is ready for snow, sleet and rain, but you can stay indoors thanks to a Bluetooth antenna that is strong enough to go through a steel shipping container. Bluetooth communications also means you’ll climb ladders less during BAM and TEOM flow calibrations.

Adjust the mechanical flow controller of an air sampling canister with minimal equilibration time. Most flow meters are slow to equilibrate to new flow rates. This can make the simple adjustment of the flow controller set screw of a SUMMA or TO-Can canister an arduous process. Alicat’s Whisper-series portable flow standards (MWB series) have extremely low pressure drop, so they respond rapidly to changes in flow rates, even at 0.5 ml/min. Low pressure drop also makes the Whisper nearly invisible to the canister, ensuring that the volumetric flow rates are also accurate.
