The blue bottom part, where the probe is, what are its dimensions? How thick it is?

The bottom of the blue probe is 3/4" and the probe is tapered. Near the top it is 7/8". The top of the probe around the seal is 1".

I received the tester but when I turn it on ,its reading is r1.2. Is that correct before I test the water reading.

Yes, it's fine. The r1.2 is the software's version number.

What is the settling time for the ORP meter in weak redox solution such as tap water? 20 seconds, 1 minute, hours for stable reading?

I can usually get a nice steady usable reading within 1 minute. If I'm being picky about the accuracy, I'll wait about 5 minutes. If I'm just trying to make a point on showing the antioxidant or oxidating potential of drinking water then I'm looking at about 20-30 seconds per sample of drinking water.
