Portable Precision Ready for the Field
The OHAUS Defender™ 3000 i-D33P75SD is a portable field-test scale weighing up to 75 kg at 0.02 kg readability on a painted steel diamond-plate base — built to be carried to the load rather than the load carried to it. For receiving docks, field checks, and anywhere a fixed bench scale isn't practical.
-
Bright LCD with color alerts for checkweighing. In Checkweighing mode the display changes color — yellow, green, red — so an operator knows at a glance whether a load is under, in, or over the target range.
-
Made to travel. ABS plastic indicator and case on a powder-coated steel base, with a flexible coiled cable that extends up to 9 ft so the display goes where the operator is.
-
Versatile. Parts counting, checkweighing and totalization built in, with RS232 included and USB or Ethernet available for printing and data capture.
-
125% overload protection, auto-zero tracking, selectable span calibration points, Geo Code gravity adjustment, and software menu lockouts.
Every scale we ship arrives calibrated, with a NIST-traceable certificate. If you keep an equipment register, we'll assign the ID, apply the sticker, and hand you documentation your auditor will accept — on day one, not on the next service visit.
