Dual Channel UV Light Meter
Light Meter Features
The Model 202 UV Light Meter is dual channel allowing 2 different UV wavelengths to be measured with a single probe i.e., 365 nm and 400nm. This versatile meter is ideal for those applications when different photopolymers are used requiring different wavelength measurements, i.e., 3d printing and UV Curing. The Model 202 is also ideal for Medical and Disinfecting as research is completed requiring various UV wavelengths.
The probe wavelengths available are (see graph below):
- Near UV: 365nm, 400nm, 420nm, and 436nm
- Mid UV: 300nm
- Deep UV: 220nm, 254nm, 260nm, and 280nm
- Custom wavelength are also possible
