I needed this to level out the platen on my wide format printer, we’re talking about fractions of a mm tolerance that were causing the print carriage to rub. After using steel thickness gauges to level everything out, we were still getting a slight bit of blur across the travel. Bring in a $300 level I never knew I needed. First, you have to calibrate this yourself. Look up some videos and find a VERY stable table or just go straight to the concrete like I did, just make sure the floor is clean and there is no lose debris. Place some tape marks and take your time alternating directions. Once calibrated, you’ll be able to capture the slightest inaccuracies. 0.0002” per foot tolerance is no joke. We were able to plum up the platen in no time and fix the detail issue with the printer. Life saver! Would have never been able to achieve the same results using an ordinary level, not even close. It’s expensive for what it is, but everything about it is precision machined and the glass vial is insanely sensitive. The 12” version I purchased actually comes with 3 total levels. I knew it had an extra one on the front for a second axis, but it also has another for a 3rd axis located in the middle where the finger holes are. At this price and sensitivity, I wish it came with a case. It’s pretty robust and the main vial has a cover, but I’d like to give it some extra protection anyway.

It can be adjusted by turning the knurled knob on the side of the level, making it easy for quick leveling tasks. - Durable Fine Finish - The base is made from cast iron and is precision-machined on the reference surface to increase durability.

It is cardboard and relatively well made. The lid slips entirely over the lower part of the box. The lid is colored red and says Starett a lot. **Q: Does this level come with certs from starret?** A: Depends on what you mean by "certs". There is a card that says "A bubble movement of 1 division (1/10") on main vial indicates an elevation of .005" per foot." The accuracy of this number is not specified - could be .004" or .006", no way to know. However, it is definitely very sensitive - more than is useful for most purposes. There is a screw to adjust the vial so that it is level - turn the assembly around on a flat and "level" surface, and the indication should be the same in both directions, or adjust the screw so that it is the same, and then it will be accurately reading the tilt of the surface. **Q: can i get a replacement bubble cylinder for the primary bubble** A: There are 2 options that we have for replacing the bubble cylinder's. 1 option is replacing the vial w/ solution only but you must know how to install it properly or option 2 would be to purchase the tube and plug vial that is already set properly inside the silver casing. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing precision! *by C***. on October 15, 2024* If you thought a good hardware store level was precise, think again.
