Whatever the application…whatever the scale platform...there’s an Ohaus Indicator to complete the picture. Engineered for easy use, the all-new Ohaus CD Indicators feature smart software and hardware enclosed in a sharp contemporary design.

All Ohaus indicators offer multiple functions, easy-to-read displays and a standard RS232 interface. And you can link to any Ohaus Bench Scale– or any other scale system– with up to four load cells. And a variety of capacities and platform sizes mean you can create exactly the right combination for your operation.

CD-11 Ohaus Scale Indicator

Ohaus digital scale indicatorsThe Ohaus CD Industrial Indicator (CD11) is the shape of things to come! The Model CD-11 offers functions like basic weighing and parts counting. Smart software and hardware are enclosed in a sharp contemporary housing. Designed to support up to four analog load cells in industrial and laboratory applications.

The Ohaus CD-11 indicator and General Purpose Champ Bench Scales are upgraded to extend their versatility, giving you more performance for the same value and more utility in light industrial applications. The new Ohaus CD-11 Champ line of industrial scales feature the following improvements:

  • Intuitive counting operation
  • Standard RS232 for easy integration
  • Impact-resistant housing for durability
  • Ounce weighing unit plus pounds, kilograms, and grams
  • Backlit LCD Display - new backlight display enhances operations, especially in dim light situations
  • Display Hold Mode - Initiated manually, semi-automatically or automatically, this feature allows you to freeze the highest stable reading on the display. For weighing bulky items that may block your view of the display and prevent you from reading the results, this feature comes in handy for shipping, receiving and other general-use applications.
  • Geographical Adjustment Function - User selectable calibration factor to adapt the scale to local gravitational conditions. It also allows second step verification at the MO level or any accredited dealer location as a value-added service.
  • Enhanced Span Calibration Range - Span calibration rance is increased from 20%-100% to 5 lb/kg-100% of full scale capacity. A wider range gives you more options when you have limited calibration weights especially when calibrating heavier capacity scales.
  • Dedicated Tare Key - Following the CW-11 indicator interface, the new CD-11 now has a dedicated key for quick tare operations.
  • Automatic Printing - Allows multiple auto print options: continuous, interval and on stability, just like the CW-11
  • Legal for Trade Type Approvals - NTEP and Measurement Canada 5000e, EC/OIML 10000e
