The 85000 Series provides legendary

Hobbs performance and reliability in a

technically advanced quartz package.

The Quartz Plus features a highly reliable

drive mechanism, an improved odometer

gear train, and a snap-together integrated

chassis. The chassis fits into a shockproof,

totally-sealed case made of an engineered

plastic that is impervious to acids and

solvents.

To ensure our high standards of quality, all

parts are in-process inspected. Every

Quartz Plus meter must pass 100% function,

burn-in, and timing accuracy test before

shipping.
