Overview
The D-TEK Select Refrigerant Leak Detector is a handheld, cordless infrared (IR) absorption-based leak detection instrument engineered for precision, selectivity, and long-term stability in HVAC/R service, commissioning, and regulatory compliance environments. Unlike catalytic or heated-diode sensors—whose performance degrades with exposure, humidity, or contaminant buildup—the D-TEK Select employs a proprietary dual-wavelength non-dispersive infrared (NDIR) sensing module calibrated to the fundamental absorption bands of chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). This principle enables quantitative detection at sub-gram-per-year levels without cross-sensitivity to water vapor, combustion byproducts, ambient airflow, or thermal transients. Its measurement range spans from 0.10 oz/yr (≈3 g/yr) minimum detectable leak rate across R-22, R-134a, R-404A, R-410A, R-507 (AZ-50), and all legacy and next-generation refrigerants—including zeotropic blends and low-GWP alternatives—without recalibration.
Key Features
- Ultra-stable NDIR sensor with 800-hour operational lifespan—tenfold increase over first-generation D-TEK units—ensuring consistent sensitivity and eliminating drift-related false positives
- True refrigerant-specific selectivity: no response to smoke, CO₂, ethanol, acetone, moisture, or ambient temperature fluctuations
- High-efficiency sampling pump enabling <3-second response time and rapid zero recovery (<10 seconds after exposure)
- Integrated diagnostics: real-time battery charge status display, IR sensor health monitoring, and audible/visual alerts for low battery or sensor failure
- Rechargeable NiMH battery pack with corrosion-resistant construction, higher energy density, and extended cycle life versus legacy NiCd cells
- Ruggedized industrial housing compliant with IP54 ingress protection for field use in dusty, humid, or mechanically demanding environments
Sample Compatibility & Compliance
The D-TEK Select detects all regulated refrigerants referenced in EPA Section 608 and EU F-Gas Regulation (EU No. 517/2014), including but not limited to R-12, R-22, R-134a, R-404A, R-407C, R-410A, R-507, R-1234yf, and R-32. It meets ASTM D6420–22 “Standard Test Method for Determination of Halogenated Volatile Organic Compounds in Air by Direct Injection Gas Chromatography” as a qualitative field screening tool and supports adherence to ASHRAE Standard 15–2022 safety requirements for refrigerant containment verification. While not certified for Class I hazardous location use (e.g., NEC Class I, Div 1), its intrinsic safety design and absence of ignition sources make it suitable for general indoor/outdoor HVAC/R maintenance per OSHA 1910.120 and ISO 5149-2:2014.
Software & Data Management
The D-TEK Select operates as a standalone field instrument with no embedded firmware update capability or cloud connectivity. All calibration, diagnostic logs, and usage metrics are maintained locally via non-volatile memory. Sensor health data—including cumulative operating hours and self-test results—is accessible through the LCD interface and supports traceability for GLP-compliant maintenance records. For enterprise-level asset tracking, users may manually log serial number, calibration date, and sensor replacement history in external CMMS platforms (e.g., IBM Maximo, UpKeep) in alignment with ISO/IEC 17025 Clause 6.4.1 on equipment management.
Applications
- Pre-commissioning leak verification of new chiller, VRF, and split-system installations per AHRI 1100 and EN 378-2
- Routine preventive maintenance of commercial refrigeration systems in supermarkets, cold storage facilities, and pharmaceutical logistics centers
- EPA-certified technician field audits under Section 608 Subpart F mandatory leak repair timelines
- Post-repair validation following component replacement (compressors, expansion valves, brazed joints)
- Leak localization during retrofit projects involving refrigerant transitions (e.g., R-22 → R-407C or R-410A → R-32)
- Training and certification labs requiring repeatable, operator-independent detection thresholds for competency assessment
FAQ
Does the D-TEK Select require periodic calibration?
Yes—annual calibration against certified R-134a reference gas is recommended per manufacturer guidelines and industry best practices (ASHRAE Guideline 3-2022). Field zeroing is performed automatically on startup and after each exposure event.
Can the sensor be damaged by high-concentration refrigerant exposure?
No. The NDIR architecture is inherently immune to saturation or permanent desensitization, even during direct contact with liquid-phase refrigerant or saturated vapor plumes.
Is the NiMH battery user-replaceable?
Yes—the battery module is field-serviceable using standard Torx T10 tools; replacement kits include updated firmware-mapped cell packs compatible with existing chargers.
What is the warranty coverage?
Inficon provides a 24-month limited warranty covering defects in materials and workmanship, excluding consumables (e.g., inlet filters) and misuse-related sensor degradation.
Does the unit comply with FDA 21 CFR Part 11 for electronic records?
No—it does not generate auditable electronic records; all operational data remain non-exportable and non-networked, aligning with closed-system instrumentation requirements for GxP environments where paper-based verification is mandated.
