Doran 7400-Checkweigh Scale

– Washdown Safe Construction
Superior washdown protection has been engineered into the Model 7400 stainless steel checkweigh scale. From the heavy gauge stainless steel to the innovative gasket design, this scale meets the NEMA4X and IP69K classifications for washdown protection.

Single Pushbutton Operation
Simple, one-button operation—what could be easier? Press Zero and the bright red LED display shows 0.00.

Big, Bright Checkweigh Indicators
Over-Accept-Under indicators can be used to check if the product being weighed meets a target weight.

Rugged and Reliable
Our engineers designed the 7400 to survive the harshest industrial environments with maximum reliability. The gasketed four-screw case, the stainless steel Zero button, and a watertight LEXAN® lens help achieve that goal.

1000% Overload Base

5 Benefits of Using a Checkweigher Scale
Doran Checkweigher scales are different than basic scales, because they have a programmable tolerance and advanced features that no other manufacturer offers. The tolerance allows an operator to input a range of weight and will indicate through different colored lights whether the item weighed is within that tolerance, above, or below the target.

Checkweigher Scale BenefitsThey have been used by companies in a number of different industries, including industrial, chemical engineering and the food industry, and have been beneficial for those companies. Here are five benefits of using a Checkweigh Scale.

1. Enhances Accuracy and Reduces Product Giveaway

The main benefit of using a Checkweigher scale is savings. The ability to produce a product at an accurate weight leads to bottom line savings because materials are not wasted and processes do not need to be repeated. In many cases these weighments are so critical, that they determine whether a plant is profitable or not.

For example, a mushroom grower used a Doran Checkweigher scale to eliminate waste during packing. By reducing over packing, they were able to increase productivity by 5,000 lbs. a day and save $39,600 over the course of a year.

2. Ensure Product Quality

The weight of a product is one of the vital benchmarks that is measured during the quality control process, whether it is for a consumable good or an automotive part. Being able to make an accurate, fast measurement that is sent to a PC for statistical analysis is one of the key functions of quality control.

A baker used a Doran Checkweigher scale while baking their English muffins. The company uses a machine to separate their dough into balls that are then baked into the muffins. If the dough balls are overweight, they will not cook all the way through and reduces profitability. If the dough balls are underweight, they will be overcooked. Using a Checkweigher scale helps the bakery to check the weight of the dough throughout the process and recognize any problems early.

3. Meet Regulatory Requirements

Using a Checkweigher scale helps to guarantee accuracy in weight. This is especially important for companies who sell products at a retail level where there is a product weight shown on the package. Each state in America has a different regulatory agency which is responsible for testing the weights of products. If products are over or underweight, the agency can enforce significant fines on the producer. Measuring throughout the manufacturing process is a great way to ensure that this doesn’t happen.

4. Provide Accurate Data to Better Manage a Process

A Checkweigher can be an important part of the quality control process. Weighing ingredients, following a formula, and weighing the finished product gives management the opportunity to check all aspects of the production process. They can identify which parts are running well and which need improvement.

In the baking example from earlier, if the baker find inconsistencies in the size of the dough balls, it is an indication that the machine is not running correctly. This indication can help them better manage their production process and improve it.

5. Track Productivity

Some systems can also track an operator’s output. This provides management with information on who measured, how long it took, when they started, and when they finished measuring. The systems provide actionable data and information which allows businesses to improve productivity and their processes.
