Flame-Proof Atmospheric Sampler FCC-1500D

Overview

The Flame-Proof Atmospheric Sampler FCC-1500D is a certified intrinsically safe sampling instrument engineered for reliable, long-duration collection of airborne contaminants in hazardous environments—specifically Class I, Division 1 or Zone 1 locations where flammable gases, vapors, or mists may be present. Designed in strict compliance with GB 3836.1–2010 (equivalent to IEC 60079-0) and GB 3836.4–2010 (IEC 60079-11) standards for explosion-proof electrical equipment, the FCC-1500D integrates microprocessor-based timing control with dual-power capability (AC/DC), enabling uninterrupted operation in both fixed-site monitoring and mobile occupational hygiene applications. Its core function is volumetric air sampling at precisely regulated flow rates—critical for subsequent gravimetric, chromatographic, or spectrometric analysis of airborne toxins including VOCs, heavy metal aerosols, organic solvents, and respirable particulates. The unit’s compact footprint (100 × 50 × 110 mm), low acoustic signature (≤55 dB), and wide operational temperature range (–25°C to +45°C) support deployment across industrial hygiene surveys, mine ventilation studies, confined-space entry assessments, and indoor air quality (IAQ) investigations under GLP-aligned field protocols.

Key Features

• Intrinsically safe design certified per Chinese national explosion-protection standards (GB 3836 series), suitable for use in petrochemical plants, pharmaceutical cleanrooms with solvent handling, paint spray booths, and underground mining operations.
• Dual-mode programmable timer: user-selectable countdown from 1 minute to 99 hours 59 minutes; automatic power cutoff upon completion ensures consistent sample volume and eliminates operator dependency.
• High-stability diaphragm pump delivering calibrated flow rates of either 0.1–1.5 L/min or 0.1–3 L/min, with factory-traceable calibration verified against primary flow standards (±5% full-scale accuracy).
• Rechargeable nickel-cadmium battery pack (10 V DC) providing up to 24 hours of continuous sampling on a single charge; standard charging current 300 mA; full recharge time: 14–16 hours.
• Robust housing fabricated from AS/ABS engineering thermoplastics, treated for moisture resistance, dust ingress protection (IP54-equivalent surface sealing), and electrostatic dissipation—critical for static-sensitive environments.
• Front-panel membrane keypad with tactile feedback and physical keyguard design to prevent accidental activation during transport or field handling.

Sample Compatibility & Compliance

The FCC-1500D is compatible with standard 37-mm and 47-mm filter cassettes (e.g., PVC, PTFE, mixed cellulose ester), sorbent tubes (e.g., activated charcoal, silica gel, Tenax TA), and impingers used in OSHA, NIOSH, and EPA Method-compliant sampling protocols. It supports both personal (belt-mounted) and area (tripod-mounted) configurations. Regulatory alignment includes conformance with GB/T 17061–1997 (Workplace Air Sampling Specifications), GBZ 159–2004 (Standards for Air Sampling in Workplace), and technical equivalency to ISO 7203-1:2015 (Air Quality — Sampling Pumps). While not CE-marked or ATEX-certified, its GB 3836 certification permits deployment in Chinese-regulated hazardous zones and serves as a baseline reference for third-party IECEx evaluation.

Software & Data Management

The FCC-1500D operates as a standalone hardware platform without embedded firmware-based data logging or Bluetooth/Wi-Fi connectivity. All operational parameters—including start time, set duration, and real-time countdown—are displayed on a high-contrast LCD screen. For audit-ready documentation, users are required to record sampling metadata manually or integrate with external electronic lab notebooks (ELNs) compliant with 21 CFR Part 11 (when used in regulated pharmaceutical or contract research settings). Calibration certificates and maintenance logs must be retained per ISO/IEC 17025:2017 clause 7.7 requirements for testing and calibration laboratories.

Applications

• Occupational exposure assessment per GBZ 2.1–2019 (Occupational Exposure Limits for Hazardous Agents in Workplace Air)
• Pre-shift and post-shift monitoring in refineries, chemical synthesis units, and adhesive application facilities
• Respirable crystalline silica (RCS) and diesel particulate matter (DPM) sampling in tunneling and quarrying operations
• Indoor air quality baseline studies in newly constructed buildings undergoing VOC off-gassing evaluation
• Emergency response air sampling during chemical spill incidents under MSA (Mine Safety and Health Administration)-aligned field SOPs

FAQ

Is the FCC-1500D certified for use in Zone 0 hazardous areas?
No. It is rated for Zone 1 (or Class I, Division 1) per GB 3836.4–2010 and is not approved for continuous operation in Zone 0 (continuous explosive atmosphere).
Can the flow rate be adjusted in real time during sampling?
No. Flow is preset via mechanical or calibrated digital regulator prior to initiation; no in-situ adjustment is supported.
What is the recommended calibration interval?
Per GB/T 17061–1997, calibration shall be performed before each sampling campaign and after any impact event or battery replacement; annual verification against a primary flow standard is advised.
Does the unit support external data export or USB interface?
No. The FCC-1500D has no digital output ports or memory storage; all timing and status information is displayed locally only.
How should the Ni-Cd battery be maintained for optimal service life?
Store in a dry, ventilated environment below 30°C; perform a full charge-discharge cycle every three months if unused, and avoid deep discharge below 1.0 V per cell.
