Standards apply from the very beginning with design qualification. At the customer location equipment is validated and verified via initial and ongoing tests described in…
Accuracy in weighing or in counting is no laughing matter when it comes to complying with rules governing net content and average weights. It is also important from a cost management perspective.
Selecting the correct ultrasonic cleaning solution is important not only to ensure thorough cleaning but also to avoid damaging the items being cleaned in the ultrasonic equipment.
Scales and balances are precision instruments. People using these instruments should be able to answer these questions: How secure is your weighing data? How accurate are your scales? What is the degree of protection from dust and moisture?
Incorrect scale specifications and term definitions can lead to problems when digital scales and balances are part of precision manufacturing processes.
Non-conductive materials can carry an electrostatic charge that can generate an electromagnetic field between what is being weighed and the precision balance itself, impacting accuracy.
Multilfrequency ultrasonic cleaners cover the spectrum across intensive industrial ultrasonic cleaning to delicate operations such as an ultrasonic jewelry cleaner.
Moisture content can be measured quickly and easily using a moisture analyzer or moisture balance such as the Kern models available from Tovatech LLC.
There’s no doubt that using counting scales can save time and money. Easier to explain is time, because these accurate tools can do in seconds or minutes what it would take hours to count by hand.
Connecting a meter to a PC with an RS-232 interface to transfer flow meter readings into Excel via the Windows HyperTerminal program.
