Durable Compact Scales for the Toughest Industrial Weighing Environments

The multipurpose Ranger 4000 is the right tool for industrial weighing applications in which value is
important but quality, durability, and functionality cannot be compromised. Portable with die-cast
metal housing and a rechargeable battery, this scale is equipped with seven application modes that
can provide results for many industrial weighing and measurement needs.

Standard Features:

Sturdy metal housing and slip-resistant rubber feet provide the protection, stability and
long product life needed for tough industrial weighing.

The most user-friendly scale on the market features SmarText™ for easy operation and setup
to ensure efficiency in the workplace.

With the largest display in its class, checkweighing LED indicators and backlit LCD display,
the Ranger 4000 can function in almost any industrial environment.

Application Modes:

• Weighing—Determine the weight of items in the selected unit of

• Percent Weighing—Measure the weight of a sample displayed as a
percentage of a pre-established reference weight.

• Parts Counting—Count samples of uniform weight.

• Check Weighing/Percent/Counting—Compare the weight/percent/
count of a sample against target limits. Choose from Checkweight,
Checkpercent or Checkcount.

• Accumulation—Totalization of weight, count or percent. Calculates
total accumulated weight, count or percent of separate items.

• Dynamic Weighing—Weigh an unstable load. Scale takes an average
of weights over a time period.

• Display Hold—Manually or automatically holds the last stable weight
on the balance display. Activated by setting time interval of Dynamic
Weighing to zero.

Metal Housing Ensures Protection

With die-cast sealed metal housing and slip-resistant rubber feet, Ranger
4000 is built to maximize product life and withstand heavy duty use and
ensure accurate operation in industrial environments.

White LED Display Illuminates Results

Ranger 4000’s bright white 1.5″ LED display is 57% larger than displays
on other scales in its class. Coupled with checkweighing LEDs and
audible indicators, Ranger 4000 is built to stand up to the challenges
often faced in industrial weighing.

Intuitive Software Supports Simple Navigation

Powered by SmarText™ software, Ranger 4000’s simple navigation works
in tandem with the scale’s dedicated keys to create a user experience

Frequently Asked Questions

Please see below for answers to frequently asked questions.

A calibration certificate proves the accuracy of your weighing equipment. It is very likely that if accuracy matters in your workplace, certification will be required by your industry regulators. They are straightforward to get hold of though. Just ask our team.

If you are trading or transacting anything by weight, you will probably need to demonstrate your weighing equipment is verified for trade use. This gives your customers confidence in your business and will make sure buying and selling run smoothly. We can help get you with relevant approvals for your equipment.

The answer will vary depending on how your equipment is used. As a minimum, we typically recommend once a year but our team can provide advice based on your individual circumstances.

The International Organization of Legal Metrology (OIML) has established standards for the classification of calibration test weights. Varying from E0 & E1, which are the most accurate to M2 which are commonly used for calibrating platform scales, floor scales and other industrial weighing instruments.

As a rough guide we have listed desired accuracy against class below.

+/- 0.1% – UNclassed Proof Load Test Weights
+/- 0.05% – M3 (Check/calibrate coarse scales)
+/- 0.005% – M1 (Check/calibrate standard scales)
+/- 0.0015% – F2 (Check/calibrate portable balances)
+/- 0.0005% – F1 (Check/calibrate precision balances)
+/- 0.00015% – E2 (Check/calibrate analytical balances)

The choice of weight class depends on the intended use and the level of accuracy required for a particular application. If you’re unsure, talk to our team who can advise you on the right class for your equipment.

If you’re sending a scale back to us for recalibration, it is ideal to use the original packaging. If this is not available choose a sturdy well-padded box to avoid shocks. Where possible, protect the load sensor by removing the weighing pan and any under-pan support and pack these separately in the box. You may be able to use the equipment’s locking pins or screws too.

Do ensure all the paperwork, including your contact details, is included to ensure we can return it once calibration is complete.
