Starrett 6" electronic digital caliper resists coolant, water, dirt and dust.

Starrett catalog number 798A-6/150.

The Starrett 798 electronic caliper provides an IP67 level of protection against foreign matter in hostile shop environments. In addition to being coolant and water resistant, the 798 also offers excellent protection against chips, dirt, dust, and other contaminants. The extra large LCD (character height 0.310") makes the 798 exceptionally easy to read. All 798 models also include an output port for RS232 equipped devices. While there are other IP67 electronic calipers available, only the 798 is a Starrett - for a century and a quarter, the tool of choice for the most experienced toolmakers and machinists when the measurements are most critical.

According to IEC529, in IP67 the first number "6" identifies protection against ingress of dust and the second number "7" identifies submersion in water under standardized conditions of pressure for 30 minutes.

With this caliper you can set zero at any position, read inches or millimeters, and lock the slide in position.

There is a manual on/off button, plus the caliper turns itself off after thirty minutes of inactivity.

Chris Chris' Tips
Here are some tips on using calipers.

What is the difference between accuracy and resolution?
Accuracy—indicates how close a measured value is to the true quantity of what is being measured.
Resolution—is the smallest increment the system can display or measure. It's one division on a dial, or the smallest increment of the righmost digit on a digital display.
