FP-25 Calibrator Kit for Air Quality Monitoring

FP-25 Calibrator Kits for Air Quality Monitoring audit and calibrate PM10 and PM2.5 particulate matter samplers and air quality testing devices to regulatory standards.

PM air monitor compatibility. Compatible with all PM air monitors: TEOM, Partisol, Beta Attenuation Monitors (BAM), T640.
Easy integration. A Bluetooth antenna plus our Alicat Connect app allows you to remotely read air sampler measurements, with added data logging capabilities for integration with data management software.
Accurate, multi-variate measurement. NIST-traceable mass flow, volumetric flow, pressure, and temperature measurements to ±1% of reading.
Portable & durable. The portable, battery-powered calibrator mounts directly to your air monitoring (FRM or FEM) instrument to negate the effects of wind gusts. Built to withstand any weather, the FP-25 calibrator is IP67 rated and has internal sensors that are accurate from -30°C to +60°C and up to 95% relative humidity.
