EIT 2.0™ UVKey g254 — Precision UVC Dose Measurement for Critical Disinfection Control
The UVKey g254 is a purpose-built ultraviolet UVC radiometer engineered for rigorous measurement of germicidal energy at 254 nm. Designed to enable precise control of UV dose in demanding environments, the UVKey g254 delivers true, NIST-traceable UVC dosimetry for applications where measurement accuracy drives process efficacy and regulatory confidence.
Core Technical Capabilities
-
Optimized Spectral Response: Sensitive across the 245–265 nm germicidal band with superior out-of-band rejection (Optical Density >4), ensuring measurement fidelity for low-pressure mercury and germicidal UV systems.
-
Robust Dynamic Range: Measures irradiance up to 10 mW/cm² and reports energy dosage from 0.001 mJ/cm² to 999.9 J/cm², switching between units (mJ/cm² to J/cm²) to maintain engineering clarity.
-
Precision Accuracy & Repeatability: Delivers ±5% typical accuracy with repeatability <1%, critical for benchmarking disinfection exposure in controlled environments and validating process compliance.
-
Lambertian Spatial Response: Approximates cosine response to irradiance incidence, minimizing geometric error in non-collimated UV fields.
-
NIST-Traceable Calibration: Calibration tied to a low-pressure mercury standard ensures traceability and confidence in reported dose values.
-
Industrial-Grade Durability: IP67 sealed enclosure and RoHS3 compliant construction provide robust protection against dust and spray for field use.
Design for Performance and Usability
-
Single-Button Operation: One-touch control with a backlit 4-digit LCD provides immediate numerical readouts of energy dose without interpretive ambiguity.
-
Compact Form Factor: Minimal footprint (50.8 × 38.1 × 12.7 mm; ~19.8 g) reduces shadowing effects and enables placement adjacent to UV sources or treatment zones.
-
Clear Calibration Lifecycle: Six-month recommended calibration interval or up to 500 J/cm² ensures long-term measurement consistency with automated CAL EXP prompts.
Application-Ready for Critical Environments
The UVKey g254 is ideal for healthcare facilities, long-term care, laboratory research, and sterilization process validation, where quantitative assurance of UVC exposure is essential. By replacing subjective film-based methods with direct electronic measurement, UVKey enhances operational reliability and process control.
