I'm looking for a meter which will measure from 365- 470nm. Do you have one?

We don't have meter in this measurement range.

Would this be good to test for 311n narrow band UVB therapy bulbs?

sorry this model only for UVA, another model UV340B ( ASIN: B07MH4YBTQ ) can test both UVA and UVB, range 290~390nm.

Does this separately measure uv-a and uv-b? because of the different effects of these wavelengths, i need to measure them independently.

Test range from 290~390nm, can not test UV-A and UV-B seperately. We have model UVA365 which ASIN is B07M675FXH in our store, this is only test UVA, you can check
