Overview
The JP-5000 Digital Display Timed Air Sampler is a microprocessor-controlled, constant-flow sampling instrument engineered for precision collection of airborne contaminants in occupational, environmental, and public health monitoring applications. Designed in collaboration with Tokyo Deodorant Co., Ltd. (Japan), it operates on the principle of volumetric displacement via a brushless DC diaphragm pump, maintaining stable flow rates across variable backpressure conditions—critical for compliance with ISO 16000-1, ASTM D5116, and OSHA Method 0018 protocols. Its compact architecture (137 × 88 × 55 mm) and ultra-lightweight design (≤0.5 kg) enable both personal (belt-mounted) and stationary sampling configurations without compromising flow integrity under typical filter or sorbent tube loading.
Key Features
- Constant-flow control system with real-time digital display of instantaneous flow rate (0.1–5 L/min) and elapsed sampling time
- High-pressure diaphragm pump delivering ≥60 kPa maximum vacuum pressure—capable of sustaining target flow through high-resistance media (e.g., PTFE filters, activated charcoal tubes, XAD-2 resin)
- Flow stability ≤5% over full operating range; accuracy ±2.5% FS (full scale) calibrated against NIST-traceable rotameter or primary standard flowmeter
- Precision timing circuitry with ≤±0.1% deviation—supports single-stage or multi-stage programmed sampling (e.g., 8-hr TWA, 15-min STEL, or custom intervals)
- Dual-power architecture: AC adapter (100–240 VAC, 50/60 Hz) or six AA alkaline/rechargeable NiMH batteries enabling >10 hours continuous operation at 1 L/min
- Low-noise operation (<45 dB(A)) suitable for indoor, classroom, or office environments where acoustic disturbance must be minimized
- Robust housing rated IP54 for dust and splash resistance; compliant with IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity)
Sample Compatibility & Compliance
The JP-5000 supports standard 37-mm and 47-mm membrane filters (cellulose ester, PTFE, PVC), glass fiber filters, and sorbent tubes (e.g., coconut shell charcoal, silica gel, Tenax TA) used in EPA TO-17, NIOSH 5515, and ISO 16017-1 methodologies. Its flow regulation meets the performance criteria specified in EN 1232 (personal sampling pumps) and GB/T 17061–1997 (Chinese national standard for air samplers). While not intrinsically safe, the unit may be deployed in non-hazardous zones (Zone 2/22 per IEC 60079-0); optional ATEX-certified variants are available upon request for explosive atmospheres.
Software & Data Management
The JP-5000 operates as a standalone field instrument with no embedded data logging or Bluetooth/Wi-Fi connectivity. All operational parameters—including start/stop timestamps, total sampled volume (L), and average flow (L/min)—are retained in non-volatile memory and viewable on the LCD screen post-sampling. For audit-ready documentation, users are advised to record field data manually or integrate with external electronic lab notebooks (ELNs) compliant with 21 CFR Part 11 requirements. Calibration certificates traceable to national metrology institutes (e.g., NIM China, NMIJ Japan) are provided with each unit shipment.
Applications
- Occupational hygiene monitoring of respirable dust, metal fumes (e.g., Cr(VI), Pb), VOCs (benzene, formaldehyde), and acid gases (HCl, SO₂)
- Indoor air quality (IAQ) assessment in schools, hospitals, and residential buildings per ASHRAE Standard 62.1
- Environmental baseline surveys near industrial sites, landfills, or traffic corridors
- Research-grade exposure assessment in toxicology and epidemiological cohort studies
- Verification of local exhaust ventilation (LEV) system performance per HSE HSG258 guidelines
FAQ
Is the JP-5000 suitable for regulatory compliance sampling under OSHA or NIOSH methods?
Yes—it maintains flow stability and accuracy within the tolerances required by OSHA ID-121, NIOSH 0500, and ISO 7708 for inhalable and respirable fraction sampling when paired with appropriate cyclones or impactors.
Can the device be calibrated in-house?
Field calibration is possible using a primary standard flow calibrator (e.g., dry gas meter or electronic bubble meter) following ISO 4031 and manufacturer-recommended procedures; annual recalibration by an accredited lab is recommended.
Does the JP-5000 support pulse-width modulation (PWM) or analog output for remote monitoring?
No—the unit has no analog voltage/current outputs or digital communication interfaces; it is designed for direct operator interaction and manual data capture.
What maintenance is required to ensure long-term flow accuracy?
Routine inspection of inlet filter, pump diaphragm integrity, and battery contact corrosion is advised every 100 operating hours; pump replacement is recommended after 5,000 hours of cumulative use.
Is firmware upgrade capability available?
The microcontroller firmware is fixed and non-upgradable; functional enhancements require hardware revision (e.g., JP-5000V2 with integrated datalogging).
