Ohaus R31P30 Ranger 3000 Series - 30 kg x 1g Basic Industrial Compact Scale

Ohaus R31P30 produces precise and rapid results in a variety of industrial applications. Features nine application modes, and equipped with a rechargeable battery for true portability. Large LCD backlit display includes checkweighing LED indicators and audible alarm.

User-friendly scale with SmarText™ ensures efficiency, while fast stabilization time maximizes your throughput without sacrificing accuracy. Weigh below hook offers functionality to perform specific gravity tests, or to weigh items not easily lifted onto the weigh pan. Included RS232 with optional Ethernet - second RS232 and USB offers additional data transfer capabilities or allows connection to multiple peripherals.

Ranger 3000 series of scales meets or exceeds the Class III accuracy requirements in accordance with NIST Handbook 44 and Canada’s Weights and Measures Regulations. NTEP Certified. 

Application Modes:

Weighing — Determine the weight of items in one or more weighing units -- lb, oz, lb:oz, kg or g.
Percent Weighing — With the weight on the platform easily shown as a % of a set reference weight, quickly measure and fill in packaging and formulating applications.
Parts Counting — Count parts fast for packaging and inventory control uses on the line or in the warehouse.
Check Weighing/Percent/Counting — Use the bright red/yellow/green LEDs to easily fill containers and packages by weight, by % or by a specified range of parts.
Accumulation — Keep a running total of all items, by weight, parts count or percent of reference. Great for tracking total throughput during each shift.
Dynamic Weighing — The Ranger averages the weight on the platform for a selected number of seconds, which is especially useful for weighing moving objects or in areas of excessive vibration.
Display Hold — Manually or automatically holds the last stable weight on the Ranger’s display. Allows large boxes to be weighed on the platform when the display is blocked from view. Can be used to help support accurate recordkeeping during processing.

Good quality for a good price!
Size: 6 Gauge 15FT, Size: 6 Gauge 15FT
Good value for the quality of these copper cables. Cut them to the length I needed and put a copper eyelet on one end. Wire size works good between my Victron solar charge controller and the batteries. Wire gauge will be able to handle the wattage much better than what I was using. They look much more professional than the old cables I was using also!

Be safe and always calculate the gauge wire are you need, don’t cut corners.
Size: 4 Gauge 10FT
Good quality solid copper 4 Gauge wires in red and black. Avoid aluminum wiring that has copper plating so looks like solid copper but can be dangerous if used in heavy load applications. Copper is expensive but required if amperage is high.

Durable insulation and pure copper not that cca bs
Size: 1/0 Gauge 5FT
Good quality. Solid copper, not that cca bs. Stiff and durable insulation. Used for big 3 car audio grounds on high output alternator. Great results. Will mention that it’s not as thick as some other brands but not by much. Terminals still crimped tightly with 1/0 gauge
