In 1891, inventor Seth Wheeler of Albany, New York, patented a toilet paper roll with tear-off sheets and a dispenser. Essentially, it's the modern toilet-paper roll as we know and love it.  Wheeler's mind was a cornucopia toilet paper ideas. He also received patents for a multirole toilet paper holder, a toilet paper fixture and a process for ornamenting toilet paper to give it a pleasing diamond-patterned look. He was the owner of the Albany Perforated Wrapping Paper Company, the first business to sell toilet paper on a roll.
Not long after 1891 the debate started as to the proper way to insert toilet paper into a holder.  Toilet paper when used with a toilet roll holder with a horizontal axle parallel to the floor and also parallel to the wall has two possible orientations: the toilet paper may hang over (in front of) or under (behind) the roll; if perpendicular to the wall, the two orientations are right-left or near-away.
Obviously the patent intended the "over" orientation but I bet Wheeler never thought about small children and kittens! Interestingly, as the Washington Post reported in 1989, "60 percent of those who earn $50,000 or more prefer it to be over and 73 percent of those who earn less than $20,000 prefer under." I am not sure what that means.
I am certain by now the point of this article is quite plain as it relates to metrology. When it comes to your test equipment, beyond the user's manual, how you use your equipment matters, and so do your personal preferences. We at HDCL always take these factors into consideration and welcome discussions from our customers on how they use their equipment and what is most important to them.  All of this is tremendously important in providing calibration services that are appropriate and cost conscious. Give us a call, we have answers.

Is your cleanroom down for routine maintenance and decontamination? Contamination control is vital for maintaining cleanroom environments. Pharmaceutical and semiconductor companies require especially stringent maintenance and sanitation programs to meet demanding standards for air quality, room design, and operation, such as those set by the International Organization for Standardization (ISO). ISO 14644-1, which defines guidelines for the classification of air cleanliness determined by the permissible particle size and levels of concentration, forces manufacturing facilities to maintain high standards for a contaminant-free facility to protect their equipment, products, and employees. Operational costs, long-standing cleaning procedures, and lack of proper equipment can stymie a company’s efforts to build a comprehensive maintenance program.

If your company schedules regular downtime for cleanrooms, keep in mind that it is the perfect time to have equipment calibrated. Call HDCL today to schedule the onsite calibration of equipment located in your cleanrooms!

Have you received a liquid filled pressure gauge that reads off zero with no pressure applied? Don't worry. There is an easy way to fix this problem.

Liquid filled gauges are tested for accuracy at our laboratory. However, during transport, changes in temperature and altitude may cause a shift in the gauge's internal pressure. That, in turn, causes the gauge's resting point to change.

On top of the gauge there is a rubber stopper which secures the liquid filling. Just lift on edge of the stopper to equalize the pressure inside the gauge to atmosphere. Try to position the gauge so that the air bubble inside the gauge is at the opening.

If this simple fix does not return your gauge to a zero reading with no pressure applied, of course you can ship or deliver it to Huston-DePue Calibration Laboratories for further evaluation and calibration.

In 1960, WWII Navy veteran Jay Huston and his wife Wilma opened Huston Laboratories out of their garage in Oklahoma City. After many decades of service, the business was passed down to their daughter, Linda DePue and her husband Mike, allowing Jay to focus on his passion for sail boating on Lake Hefner. In August 2016, Huston-DePue Calibration Laboratories began its third generation of family ownership when Mike and Linda's daughter, Tracy Page, and her husband purchased the laboratory. We look forward to many more generations serving our customers.
