The performance of any measuring device will change over time and must be regularly verified. A new checklist explains how to set up a performance verification plan for weighing equipment that is GMP-compliant and cost-efficient.
Understanding 4-20mA Communications
Imagine this: You’ve got your meter with 4-20mA output setup. Confidently, you flip the switch, turning it on, and then it happens: the readings are off. You’re not getting the output you need. Frustrated, you tinker with it, and still nothing. Now, you’re out of your depth. You need to get this thing working so you can get your application up and running. What are you going to do? Who are you going to call to get help? Why is this even happening? Hopefully, this situation has not happened to...

4 Types of Contaminants in Water
The EPA says that there are 4 type of water contaminants: physical, chemical, radiological, and biological. Its definition includes anything that is not an actual water molecule. That means that naturally occurring things like sediment and water weeds are considered contaminants along with things like oil and uranium. Chances are good that the type of contaminants your company needs to keep out of the water system aren’t naturally occurring. Since water is the most important element on Earth (life wouldn&rsq...
4 Signs Of Poor Indoor Air Quality To Watch For
The quality of indoor air is something most of us take for granted. Unless there is something very specific and unusual going on around us, like heavy cleaning or maybe new construction, we don’t often think about whether or not there is anything wrong with the air we breathe as we go about our daily business. The truth is, though, that indoor air quality is often worse than outdoors. Poor air circulation and well sealed, energy efficient buildings combine to trap and cause the buildup of many hazardous...
4 Key Design Criteria for Jet Mixers
Jet mixers are widely used in both municipal and industrial wastewater treatment facilities to blend the plant influent and suspend light organic solids in circular equalization tanks. Other applications for these powerful hydraulic mixers include mixing anoxic tanks and anaerobic reactors with the latter application being for industrial waste streams only. Jet mixers are the technology of choice based on their flexibility of operation and configuration in small and large diameter tanks, the highly corrosion and...
