Johnson Glo-View® Digital Level Review – Model 40-6048

Glo-View® Digital Level – Model 40-6048

Digital levels are becoming very popular throughout the construction industry. The folks at Johnson Level and Tool sent me their Glo-View® Digital Level – Model 40-6048 to evaluate. It’s a 48″ bubble level with a built-in digital component as well. This is a really nice digital level and one I’d recommend for sure. Read on to learn more about the Model 40-6048 from Johnson.

Durability & Accuracy

Durability and accuracy are the two words I’d use to describe the Johnson Glo-View® Digital Level. I’ve always been a firm believer in spending good money on layout equipment like levels. Your finished product is only as good as your ability to consistently build level & plumb surfaces. The Glo-View® Digital Level combines the best features of a quality bubble level with the advanced features of a digital level in one durable, quality tool.

The overall quality of this level is very good. Machined surfaces offer a really nice straight edge. The ends have rubber bumpers to protect the level from impact drops. These levels offer nice large hand holes which make them easy to hold when climbing ladders and working in hard to reach areas.

Bubble (Spirit) Level – The bubble level on this Glo-View® Digital Level is really nice. Johnson uses their patented Glo-View® technology to help improve readability in low light situations. The Glo-View® absorbs energy in the form of sunlight or even an LED flashlight, and then slowly releases the energy as light over several hours. I happen to really like the Glo-View® bubbles on Johnson levels, they are much easier to read and work very well.

Digital Level Features – Many of you probably think that digital levels are a bit gimmicky but I’m finding them quite useful in my day to day job. One of the best uses for digital levels on my job is checking slopes for ADA compliant ramps and entry ways. Today’s codes are getting harder and harder to comply with so having an accurate measurement of slope angles is critical.

The digital level features on the 40-6048 are really nice. You can set it up for 5 different measurement types including; degrees, percent, mm/m, in/ft in decimal and in/ft in fractional. The display is easy to read and offers a back-lit display for low light situations. The display can be rotated so you can read it from the side or top of the level depending on where you’re standing.

The level isn’t super fast when waiting for it to find the actual angle. It can take up to a couple seconds or more in some situations to report a final angle. While I don’t think this is a big issue when trying to measure slopes some folks might find it sluggish.

Another nice feature on the digital level is an easy to use calibrate mode where you can re-calibrate the level if it’s not running true after dropping it or bumping it.

Overall Impression

I really like this digital level a lot! In fact…it’s sitting under my seat in the truck as my primary level for job site visits now. This is a perfect level for guys who need the benefits of a standard bubble level and the extra features of a digital level. Johnson makes great levels and this one is no exception. Priced around $180 it’s a good value. If you’re interested in buying it online check out the following link:
