UV-C Irradiance Meter (Probe)
£850.00
NIST traceable, hand-held UV light irradiance meter with an integral sensor.
- Compact, handheld, and durable
- Simple single-button operation
- NIST traceable accuracy
- LCD display
Applications include monitoring UV-C germicidal lamp irradiance and ageing, testing UV-C transmission of materials and measuring germicidal lamp fixture leakage.
Description
Sensor
Photodiode packaged in hermetically sealed UV glass window cap.
Operation
To operate your UV meter, aim the sensor window located on the top panel of the meter directly at a UV source. Press and hold the push-button switch on the face of the meter. For best results take note of the distance the reading was taken from the UV source in order to ensure repeatable results. Battery operation voltage is viable from 9V down to 6.5V. Below 6.5V, the numbers on the LCD display will begin to dim, indicating the need for battery replacement. Under typical service load, a standard 9V battery will last approximately 2 years.

Unit conversion
Microwatts/cm to Milliwatts/cm
- 1 µW/cm² = 0.001 mW/cm²
- 10 µW/cm² = 0.01 mW/cm²
- 100 µW/cm² = 0.1 mW/cm²
- 1,000 µW/cm² 0.1 mW/cm²
Microwatts/cm to Watts/m
- 1 µW/cm² = 0.01 W/m²
- 10 µW/cm² = 0.1 W/m²
- 100 µW/cm² = 1 W/m²
- 1,000 µW/cm² = 10 W/m²
Instructions for use
- Wear skin and eye protection when checking UV-C lamps.
- Allow lamps to warm-up prior to taking readings (at least 5 min).
- Hold sensor close to lamp to measure individual lamp UV-C intensity.
- When checking aging of lamps, keep measuring distance and locations constant.
- Lamps should be replaced when output drops to about 70% of their original readings.
- If unsure of what original new values were, replace a lamp with new one and compare old one.
- Do not subject the meter to extremes in temperature, humidity, shock or dust.
- Use a dry, soft cloth to clean the instrument. Keep sensor free of oil, dirt, etc.
