This model has been discontinued by OHAUS and cannot be ordered.
The D31P30BR5 is no longer manufactured. OHAUS replaced it with the Defender™ 3000 i-D33P30B1R5 — the same 30 kg × 5 g capacity on the same 14 × 12 in stainless steel platform, with a multicolor checkweighing display, totalization, and the same NTEP and Measurement Canada approvals.
