Electronic Digital Caliper, 6", Starrett 797 2530  (Discontinued)

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

Starrett catalog number 797B-6/150.

The Starrett 797 electronic caliper provides an IP65 level of protection against foreign matter in hostile shop environments. In addition to being coolant and water resistant, the 797 also offers excellent protection against chips, dirt, dust, and other contaminants. The extra large LCD (character height .310") makes the 797 exceptionally easy to read. All 797 models also include an output port for RS232 equipped devices. While there are other IP65 electronic calipers available, only the 797 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 IP65 the first number "6" identifies protection against ingress of dust and the second number "5" identifies protection against water jets projected by a nozzle from any direction for a duration of 3 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 four hours of inactivity.
