Bench scales for basic industrial applications
The OHAUS Defender™ 3000 i-D33P30B1R5 weighs up to 30 kg at 5 g readability on a 14 × 12 in stainless steel platform — built for general weighing, parts counting, checkweighing and totalization in production, packaging, shipping and receiving. It is the current OHAUS replacement for the discontinued D31P30BR5.
-
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.
-
Tough design for industrial applications. 304-stainless steel platform, powder-coated steel tubular frame, aluminum load cell, and a durable ABS indicator housing on a steel mounting bracket.
-
Versatile. Parts counting, checkweighing and totalization built in, with RS232 included and USB or Ethernet available for printing and data capture.
-
150% overload protection and non-slip adjustable rubber feet.
-
Legal for trade. NTEP certified and Measurement Canada approved.
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.
