I am a metrologist in our laboratory. I calibrate everything from scales, load cells, timing devices to digital spirit levels. I bought this Johnson level. This lasted about a year until his death. This does NOT support calibration. It's absolute junk and I would never buy it again. Unfortunately, someone here just bought another one. I will calibrate this. If the calibration is maintained without the need for a quick calibration every time I use it, I'll update this post.
