Durable Industrial and Basic Bench Scale Bases
Building on the success of the ChampTM series of bench scales, the new OHAUS DefenderTM Bases offer two
levels of durability for the most demanding industrial applications. All Defender Bases offer removable
stainless steel weighing pans, IP67 protected single-point loadcells, steel construction, non-slip adjustable
feet and integral leveling bubbles.
For standard industrial applications, the Defender Square, Rectangular and Square Washdown Scale
Bases (Q, H and W models) offer the same folded and welded steel plate construction found in the
popular Champ and Champ II series. For basic use where budget is more of an issue, the Defender Basic
Rectangular Bases (B and V models) – available in dry-use and washdown models – offer welded tubular
steel construction for economical yet durable performance.
With NTEP certification and Measurement Canada approval, all of these bases can be used for both general
applications as well as where legal for trade performance is required.
Standard Features Include:
• Removable stainless steel weighing pans
• Steel frame construction with stainless steel for Washdown models, painted carbon steel for other models
• IP67 protected single point loadcells, with stainless steel loadcells for Washdown models,
aluminum loadcells for other models
• Adjustable, non-slip rubber leveling feet and leveling bubble
• 1:5,000 certified performance for Defender Washdown Square and Square
Bases (W and Q models), up to 1:3,000 performance for Defender
Rectangular Bases (H, V and B models)
