UV Light Irradiance and Exposure Meter
Product features
- Hand held UV meter with interchangeable sensor heads
- UV light irradiance measurement in mW/cm2
- UV light exposure measurement in J/cm2
- Choice of sensor head - depends on wavelength range to be measured
- Interference filter to select appropriate UV band and to eliminate all other unwanted radiation
- Non sensitive to infra red
- No electronic components in the sensor to avoid any possible temperature sensitivity
- Quartz disc protection on cell filter
- Carbon shielded cable (1 m)
- Microprocessor controlled
- Designed for operating at 254 nm, 312 nm or 365 nm
- Independent sensor (purchased separately) for each wavelength
- Auto ranging
