surge protector
Will a surge protector help with low voltage like a plug in voltmeter?Will they both work basically the same?

Then no. A surge protector will not indicate voltage nor will it protect you from high or low voltage as in out of spec 120V +- 10%. It will be destroyed and protect against high voltage transients ie a surge.
Likewise a voltmeter will not protect you against low or high voltage unless you are watching it and can disconnect the power fast enough or essentially no protection.
A full function power protection device will detect a surge and self destruct protecting you. It will also detect high/low voltage and disconnect. Some like my Progressive Industries HW50C will display current voltage and amps and will display a error code for a prior fault like low voltage.
To protect your AC you can:
1. Watch a voltmeter all day
2. Use a full function power protector
3. Use a autoformer
4. Turn the AC off
