ION Tiger Portable VOC Detector

Overview

The ION Tiger is a high-performance, intrinsically safe portable volatile organic compounds (VOC) detector engineered for real-time, field-deployable TVOC monitoring in industrial hygiene, environmental remediation, confined space entry, and hazardous materials response. It employs a robust, temperature-stabilized 10.6 eV ultraviolet (UV) photoionization detector (PID) sensor — the industry-recognized benchmark for broad-spectrum VOC detection without chemical-specific calibration. Unlike flame ionization or metal oxide semiconductor sensors, PID technology enables selective, non-destructive ionization of organic vapors with ionization potentials below 10.6 eV, delivering rapid, quantitative response across over 480 listed compounds — including benzene, toluene, xylene, styrene, acetone, chlorinated solvents, and many halogenated hydrocarbons. The instrument’s measurement architecture is optimized for stability under variable humidity and particulate load, minimizing drift and false positives in challenging outdoor or indoor environments.

Key Features

• Intrinsically safe design certified to ATEX II 1G Ex ia IIC T4 Ga, IECEx Ex ia IIC T4 Ga, UL 913 Class I, Division 1, Groups A–D, and CSA Class I, Division 1, Groups A–D — enabling safe operation in Zone 0/20 hazardous areas.
• Ultra-fast response and recovery: T90 < 2 seconds; full signal decay to baseline within < 5 seconds after exposure cessation — critical for dynamic leak surveys and perimeter monitoring.
• True ppb-to-ppm dynamic range: 1 ppb minimum detection limit (MDL) up to 20,000 ppm full scale, eliminating range-switching delays during transient exposure events.
• Integrated compound library: Built-in database of >480 VOCs and toxic gases with individual correction factors (CFs), accessible via on-device lookup and exportable for reporting compliance with OSHA, NIOSH, and EU REACH frameworks.
• 24-hour battery life on a single charge (rechargeable Li-ion), supporting extended shift operations without hot-swap limitations.
• Optimized human interface: Backlit, tactile keypad with large character display; icon-driven menu navigation requiring minimal operator training; intuitive one-hand operation even with gloves.

Sample Compatibility & Compliance

The Tiger detects gaseous-phase VOCs in ambient air, workplace atmospheres, soil vapor extraction (SVE) effluent, and indoor air quality (IAQ) assessments. It is not intended for use with aerosols, particulates, or condensable vapors above dew point. Its PID sensor is insensitive to common interferents such as CO₂, methane, ethane, and water vapor — ensuring specificity in humid or high-background gas environments. The device complies with ISO 16000-22 (indoor air — determination of VOCs using PID), meets performance criteria outlined in ASTM D5403 (standard test method for volatile content of coatings), and supports GLP-aligned data integrity when paired with IonScience’s compliant software suite. Calibration traceability follows NIST-traceable isobutylene standards, and routine bump testing satisfies OSHA 1910.120 and HSE COSHH requirements.

Software & Data Management

Data acquisition and reporting are managed via IonScience’s free Tiger Log and Tiger Connect desktop software — compatible with Windows and macOS. USB-C direct connection enables real-time logging, historical trend analysis, and customizable report generation (PDF/CSV). All logged data includes timestamp, GPS coordinates (when connected to external GNSS), battery status, sensor temperature, and calibration history. Audit trails meet FDA 21 CFR Part 11 requirements for electronic records and signatures when configured with user authentication and electronic signature workflows. Firmware updates are delivered securely through the IonScience support portal, ensuring continuous alignment with evolving regulatory guidance and sensor algorithm improvements.

Applications

• Industrial hygiene monitoring for compliance with TLV®–TWA and STEL exposure limits
• Leak detection and repair (LDAR) programs per EPA Method 21 and EU IED directives
• Soil vapor intrusion (SVI) screening at brownfield sites and landfill perimeters
• Hazardous waste site characterization and emergency response triage
• Indoor air quality investigations in commercial buildings, schools, and healthcare facilities
• Process safety management (PSM) verification during maintenance, turnaround, and startup activities

FAQ

What calibration standard is recommended for routine verification?
Isobutylene (C₄H₈) at 100 ppm in air is the primary calibration gas specified by IonScience and recognized by ISO and ASTM standards for PID instruments.
Can the Tiger detect methane or carbon monoxide?
No — methane (IP = 12.6 eV) and CO (IP = 14.0 eV) exceed the 10.6 eV photon energy of the UV lamp and are therefore not ionized or detected.
How often should the PID lamp and sensor be replaced?
The 10.6 eV lamp has a typical service life of 5,000–8,000 hours; the electrochemical sensor stack is field-replaceable and rated for ≥2 years under normal operating conditions.
Does the Tiger support Bluetooth or wireless data transmission?
No — data transfer is exclusively via USB-C; no onboard Wi-Fi or Bluetooth radios are included to maintain intrinsic safety certification integrity.
Is the instrument suitable for use in explosive dust environments (e.g., grain silos)?
Yes — its ATEX and IECEx certifications include dust ignition protection (Ex ia IIIC T135°C), making it appropriate for Zone 20 combustible dust locations.
