The short answer is YES, you should always protect your Instruments from Power Surge (Or Spikes), accidentally using the incorrect AC adaptor and the like.
Just to clarify, while a UPS (Uninterruptible Power Supply) is typically used for PC’s in the Laboratory or in situ in the factory, low voltage instruments like a Spectrophotometer, unless you expect a long power out, does not require this more expensive solution. A PC requires a controlled shutdown, so if you don’t need backup for long power outages, you can use a simple UPS rather than a more complex expensive one.
Instruments however often have internal battery options, or if the power is out, nothing will be working, so a UPS solution is overkill in most cases.
What you really want to protect yourself from is:
- Spikes in Power supply
- Spikes from crossing over to a generator
- Spikes from when the power is reconnected
- Plugging in the wrong AC adaptor (Most KM devices are 5v)
In this case, off the shelf “Surge Protectors” are sufficient.
