1. What is the UV Gauge Equation?

The UV Gauge equation calculates the UV exposure by multiplying the reading from a UV sensor by its calibration factor. This provides the actual UV exposure in mJ/cm².

2. How Does the Calculator Work?

The calculator uses the UV Gauge equation:

Where:

• \( reading \) — Unitless reading from UV sensor
• \( calibration \) — Unitless calibration factor
• \( gauge_{uv} \) — UV exposure in mJ/cm²

Explanation: The equation converts the raw sensor reading to actual UV exposure using the device-specific calibration factor.

3. Importance of UV Gauge Calculation

Details: Accurate UV exposure measurement is crucial for applications like phototherapy, UV curing processes, and monitoring UV radiation levels.

4. Using the Calculator

Tips: Enter the raw reading from your UV sensor and the calibration factor specific to your device. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find the calibration factor?
A: The calibration factor is typically provided by the sensor manufacturer or determined through device calibration procedures.

Q2: What are typical UV exposure values?
A: Values vary widely by application - from a few mJ/cm² for disinfection to hundreds or thousands for industrial curing processes.

Q3: How often should I recalibrate my UV sensor?
A: Follow manufacturer recommendations, typically every 6-12 months or after any significant impact to the sensor.

Q4: Can I use this for all UV wavelengths?
A: The calculator works for any wavelength, but ensure your calibration factor is specific to the wavelength you're measuring.

Q5: Why is my reading unitless?
A: Raw sensor outputs are often in arbitrary units that need to be converted to physical units using the calibration factor.
