PIONEER ANALYTICAL AND PRECISION BALANCES

The Pioneer series of analytical and precision balances are designed for basic routine weighing in a variety of laboratory, industrial and education applications. With the right combination of performance and features the Pioneer offers uncomplicated performance for all your basic weighing needs and includes parts counting and percentage weighing. The integral up-front level indicator quickly ensures the balance is level prior to use and to help adapt the balance to real life working conditions the Pioneer is designed with selectable environmental settings. When working in harsh environments, the balance can be adjusted to compensate for vibrations and other disturbances. Conversely, the balance can be adjusted for working in slow filling applications where sensitivity is a must.

Weighing Capacities
Analytical - 65g/0.1mg up to 210g/0.1mg available
Precision - 210g/1mg up to 4100g/0.1g available

COEFFICIENT OF FRICTION TESTER

The Advanced Static and Dynamic Friction Tester brings together accurate load cell measurement with advanced microprocessor technology to give the most accurate, user friendly Friction Tester system to be designed by Ray-Ran. Frictional properties of plastic film and other materials are accurately calculated with specified test conditions selected such as test sled weight, test velocity and temperature making this apparatus ideal for all types of flexible packaging, foils, paper, board, rubber, linoleum, textiles and leather.

Accurate and repeatable test results for Static and Dynamic Friction co-efficient values with normal separating loads of up to 1 kg are easily determined for any combination of materials using a standard test sled or specific peel attachment.

To calculate the static friction the apparatus records the peak friction value at the precise moment that movement occurs after which, the dynamic friction is immediately observed. To measure this peak friction value, the advanced microprocessor continually monitors the output signals of the load cell. Load cell readings are taken beyond the peak load in order to confirm that the slope of the load curve is reducing. When the static frictional value has been determined by the microprocessor the dynamic friction is measured twenty times during the selected travel distance. The result given is the average of these twenty readings. However, by displaying the results graphically on a computer, each of the twenty readings can be inspected to examine any variation in the test results over the selected travel distance.

The large on board liquid crystal display (LCD) provides simple on screen instruction and using the alpha/numeric membrane keypad test parameters such as user names, material reference numbers and batch numbers are entered and stored in operator lists for future recall and results presentation. Testing parameters such as test velocity, sled weight and settling time are also entered to give the required testing conditions. If Temperature is important to your testing requirement then the Static and Dynamic Friction Tester can be supplied with an optional heated bed. After each test has been conducted the results are displayed on the LCD giving the static and dynamic co-efficient as well as the test load result in grams. Batch statistics are automatically updated after each test and results are shown in graphical and tabular format for analysis when downloaded to the supplied PC software.

For quality control purposes the Static and Dynamic Friction Tester can be set with High and Low limits which are clearly defined when test results are downloaded showing the user instantly if the material is a pass or fail.

The apparatus is supplied as standard with Ray-Ran’s Techni-Test Windows based PC software for connection to the apparatus via an RS232 or Ethernet connection. Test results can be printed directly from the Techn-Test software or can be saved and exported as .CSV files which can be opened with Microsoft Excel in tabular form which can be manipulated to your specific requirements such as preparing a graphical presentation or copying the results to a Word document for a report presentation if required. If the apparatus is connected to the PC via the Ethernet connector over a LAN network then the RS232 can be used for connection to an optional thermal printer for direct printout by the operator.
