SKC AirChek ESSENTIAL Personal Air Sampling Pump

Overview

The SKC AirChek ESSENTIAL Personal Air Sampling Pump is an intrinsically safe, microprocessor-controlled constant-flow air sampling device engineered for occupational hygiene monitoring in industrial, laboratory, and field environments. Based on thermal mass flow sensing technology with isothermal compensation, the pump maintains precise volumetric flow rates across variable filter media resistance and ambient conditions—critical for quantitative collection of airborne particulates (e.g., respirable dust, silica, asbestos fibers) and vapors (e.g., solvents, aldehydes, organic compounds) onto sorbent tubes or membrane filters. Its UL/ATEX certification confirms compliance with Class I, Division 1 (UL 913) and Zone 1 (EN 60079-0, -11) hazardous location standards, enabling deployment in petrochemical plants, pharmaceutical cleanrooms, paint spray booths, and confined-space entry operations where explosive atmospheres may be present.

Key Features

• Constant-flow performance across a broad operational range (5–5000 mL/min), digitally calibrated and traceable to NIST standards.
• Integrated isothermal thermal mass flow sensor with automatic backpressure compensation—sustains target flow within ±5% accuracy even under load up to 50 inches water column (12.5 kPa) at –2 L/min.
• Rechargeable lithium-ion battery delivering >40 hours of continuous operation at 2 L/min (typical workflow), supporting multi-shift and extended-duration sampling campaigns without interruption.
• Intuitive 2.8-inch backlit LCD touchscreen interface with screen lock and protective polycarbonate cover—designed for gloved operation and resistant to solvent exposure and abrasion.
• Dual-status LED indicators: green (pump running), red (flow fault, low battery, or sensor error), providing immediate visual feedback during field deployment.
• Ruggedized enclosure constructed from ESD-safe, non-sparking polymer with textured anti-slip surface—meets MIL-STD-810G shock/vibration requirements and IP54 ingress protection.
• Auto-restart function upon transient flow disruption (e.g., filter clogging, tubing kink), preserving sampling integrity and minimizing manual intervention.

Sample Compatibility & Compliance

The AirChek ESSENTIAL is validated for use with standard 37-mm and 25-mm cassette assemblies (including mixed-cellulose ester, polyvinyl chloride, and polycarbonate membranes), as well as common sorbent tubes (e.g., charcoal, silica gel, Tenax TA). It supports all NIOSH Manual of Analytical Methods (NMAM) and OSHA Sampling & Analytical Methods protocols requiring constant-flow personal sampling. Device firmware and calibration records are compatible with GLP/GMP documentation workflows. While not FDA 21 CFR Part 11–certified out-of-the-box, audit trails—including start/stop timestamps, cumulative run time, average flow rate, and fault logs—are exportable via USB-C for integration into validated LIMS or electronic lab notebooks.

Software & Data Management

The pump operates autonomously without external software but includes embedded data logging for up to 100 sampling events per session. Each record stores date/time stamp, programmed flow rate, actual measured flow (mean and standard deviation), total elapsed time, and diagnostic flags. Data exports in CSV format via USB-C connection for post-processing in Excel, R, or statistical validation packages. Optional SKC AirCheck Connect mobile app (iOS/Android) enables remote configuration, real-time status monitoring, and batch calibration certificate retrieval—though no cloud storage or API access is provided to maintain data sovereignty per EU GDPR and HIPAA-aligned privacy frameworks.

Applications

• Personal exposure assessment for respirable crystalline silica (RCS), coal dust, welding fume, and diesel particulate matter (DPM) per OSHA 1910.1053 and MSHA PELs.
• Vapor monitoring of benzene, formaldehyde, and chlorinated hydrocarbons using passive badge verification or active sorbent tube analysis per NIOSH Method 1501/1600 series.
• Indoor air quality (IAQ) investigations in office buildings, schools, and healthcare facilities—especially where volatile organic compound (VOC) source identification is required.
• Pre-commissioning and routine maintenance sampling in HVAC systems, semiconductor fabrication cleanrooms, and battery manufacturing lines handling flammable electrolytes.
• Regulatory compliance audits under ISO 45001, ANSI Z88.2, and EU Directive 2004/37/EC (CARCINOGENS AND MUTAGENS Directive).

FAQ

Is the AirChek ESSENTIAL suitable for use in explosive atmospheres?

Yes—it carries UL 913 Class I, Division 1 and ATEX II 1 G Ex ia IIC T4 Ga certifications, permitting safe operation in zones where methane, hydrogen, or solvent vapors may accumulate.
Does it require annual recalibration?

SKC recommends calibration verification before each critical sampling campaign and full recalibration every 12 months by an ISO/IEC 17025-accredited laboratory using traceable flow standards.
Can it be used with conductive sampling tubing?

Yes—the pump’s ESD-safe design accommodates grounded stainless-steel or carbon-loaded polymer tubing to prevent static discharge during solvent vapor sampling.
What happens if the battery depletes mid-sampling?

The device enters low-power hibernation mode while retaining all logged data; upon recharge, it resumes normal operation without data loss.
Is firmware update capability available?

Firmware updates are performed via USB-C using SKC-provided utilities; version history and release notes are published in the technical support portal for traceability.
