Q: I have an IVD^TM but it looks different from this model. Has the design changed?
A: Yes. The Model 1135 IVD™ was manufactured by Sun Nuclear from 2002 through September of 2005. The new Model 1137 IVD 2 offers several significant changes that include:
- Simplified design, no batteries.
- Control Module is now standard.
- Four standard channels instead of three.
- Compact and Robust LEMO connectors.
- Simplified temperature correction routine now uses look-up table.

Q: I have BNC connectors, will they work with the new IVD 2?
A: Yes. Using adapters, you can convert your BNC connector to a LEMO connector. We will also retrofit any BNC connector to LEMO if desired by the customer.

Q: How do the batteries work (Can they be damaged)?
A: The Model 1137 IVD 2 does not use batteries.
