Highly recommend a hygrometer to monitor and set your humidity. With experience and trial and error you could obtain great hatch rates without one but this being only 7 highly prized eggs I'd pick up a cheap one at your local box store. Cheap or expensive all hygrometers need to be calibrated so there is no need to spend extra money on one. Small, easy to fit in incubator is what you want.
I don't recommend multiple equipment. You'll tear your hair out or lose it to worry that they all read different. Calibrate one hygrometer and use a medical thermometer to calibrate temp. A digital or glass oral or other medical thermometer is the most accurate device you can find without paying over $100. Likely you already have one in the bathroom cabinet.
Still air incubators you set temp to 101-102 F measured at top level of eggs. An incubator with fan you set temp to 99.5 F at egg level.
Auto turners are awesome. After hand turning for years I'd lost the zest to turn religiously and hatch rate suffered. Picked up a cheap auto turner and back to 90-100% hatch. Being your first hatch hand turning shouldn't be a problem. Turn at least 2 times a day and more is better.
This is a good image to guide you for air cell growth. HIgher humidity retards moisture loss in egg and lower humidity quickens. I suggest a salt test on hygrometer and setting humidity to 30%. If by day 14 your air cells are small simply take out all water and run dry for as many days as it takes to catch them up before jumping humidity to 70% for last 2 to 3 days.
Salt test:
Fill a milk cap size container with salt and add drops of water until it's saturated. I pour off any standing water.
Put hygrometer and cap with salt in sealed container for 6 hours. I use a quart size zip lock bag and allow for a small pillow of air.
Record your RH reading after 6 hours. A salt environment is 75% RH for all ranges of normal temperatures. Subtract your reading from 75 and write that number on masking tape to fix to incubator as reminder of the calibration.
Ex: Your reading is 84%, 75-84= -9 You'll always subtract 9 from your hygrometer reading for true RH.

, I have one of these incubators but i was told 60% was ideal before i found this terrific site.
, i hope all will be well and will look forward to your post of your new chicks when they hatch. 
Can't help myself. 
sorry too funny 
actually tried this 
could actually work - human incubating eggs may be possible... 
Tucked stolen mallard egg in brassier to keep warm for few days but gave it back to momma and they all hatched and made front page in the Capital newspaper. 
can't. Was front pager but don't have photo
