The various RM9 radiometer models are fully compatible with these meters/interfaces:
- Vega / Nova II (firmware version 2.44 or higher)
- Juno (1.31 or higher)
- StarLite (1.26 or higher)
- StarBright (1.18 or higher)
They are partially compatible with Ophir’s other meters (Nova, LaserStar, USBI, Pulsar, and Quasar). They will function properly with these devices, except with a narrower power range and with reduced accuracy; see specs for more details.
