ZooMed Hand-held UVB Radiometer, ST-6

Description

The human eye cannot see UV radiation, so it’s impossible to tell by looking alone when your UV bulbs need changing. Use this meter to test the relative decay of UVB in a given lamp over time. It reads in microwatts per square centimetre.

Know – don’t guess! – when it’s time to replace your fluorescent UVB lamps.
