This model has been discontinued by OHAUS and cannot be ordered.
The D31P300BX is no longer manufactured. OHAUS replaced it with the Defender™ 3000 i-D33P300B1X2 — the same 300 kg × 50 g capacity on the same 650 × 500 mm stainless steel platform, with a multicolor checkweighing display, totalization, and the same NTEP and Measurement Canada approvals.
