The smallest, lightest and most versatile wireless dynamometer.

RON 2501 is especially suitable for hot industries, for use during casting and forging in foundries etc, as well as in a variety of additional applications.

The RON 2501 has an internal mechanism to ensure that the received and indicated value is identical to the transmitted value. Under no circumstances will it indicate a different value than the transmitted one. This is an important safety feature.

The small size of the wireless load cell ensures portability and low headroom loss for any application.

The unique perpendicular hole structure of the wireless load cell neutralizes external moments thus improving safety and accuracy.

All RON crane scales and dynamometers are fully tested and supplied with a test certificate, including a fully traceable calibration chart.

Specifications
Options
Range : Up to100 yards / meters (outdoor, line of sight).

Safety Factor : Designed to 5:1.

Proof Load : Each system proof-loaded to 200% of capacity (certified) up to a test force of 400t.

Accuracy : ± 0.1% of full range.

Display : 5 digit, ½" (12mm) liquid crystal display and annunciator; two-level overload state, max. value (peak hold), low battery (load cell and indicator), tare state (gross or net), measuring units, charge, and programming instructions. Standard number of measurements per second: 1.

Functions : Zero. Tare. Low battery warnings: one for the load cell battery and the other for the hand-held indicator, displayed on the latter. Max. (peak hold). Two-level overload visual alarms. User calibration.

Units : available in the following measurement readings: metric tons, short tons (2000 lbs), kgs, lbs (lbs x 10 for capacities of 50t and above), newtons, deca newtons, k. newtons. 		Load Cell Material : Made of high-strength, aerospace quality, alloy steel, polyurethane coated.

Indicator Material : High quality ABS.

Power : 3 x AA (“finger”) 1.5 Volt Alkaline disposable batteries in the hand-held indicator and additional 4 in the load cell. Batteries rated 3AH will function for at least 1500 hours (more than two months of continuous working). Occasional use will extend the life of the batteries up to several years. Adding certain options will shorten the life of the batteries. All settings retained at power off.

Calibration : User calibration. Initial factory calibration, fully traceable (certified).

Temperature Range : Load cell: -15°F to +175°F (-25°C to +80°C). Indicator: -4°F to +158°F (-20°C to +70°C).
