DPF and EGR Filter Maintenance with Ultrasonic Cleaners
Diesel particulate and exhaust gas recirculation cooler filters lose efficiency over time. Indications include warning lights, increased fuel consumption, rough starts, stalling, and dark exhaust. Searching DPF and EGR cleaning yields many results on how owner-operators, fleet managers and maintenance shops deal with DPF and EGR cooler maintenance. Here is how an ultrasonic cleaner can extend DPF…

Ultrasonic Passivation for Stainless Steel
Stainless steels such as AISI* Types 304, 310 and 316, are favored for strength and corrosion resistance. Applications include food, chemical and pharmaceutical processing, surgical implants, architecture and transportation. Over time starting from initial fabrication, free iron and other contaminants adhere to surfaces and must be removed. Ultrasonic passivation for stainless steel accomplishes this to…
Selecting Scale Weights for Calibration Testing
Calibrating precision digital scales, analytical balances and moisture analyzers that rely on accurate weight measurement requires periodic tests using a scale weight closely matching the maximum capacity of the instrument being tested. Why Testing with Scale Weights is Important Daily we depend on weighing accuracy – such as visits to the deli counter in the…
