The most common pH meter calibration is the two point calibration and is best suited when you have a range of pH samples. The buffer solutions should bracket your expected pH sample. In this process the pH meter determines the slope and offset error for the actual pH electrode in use. This information then allows the meter to adjust the mV/pH equation of the pH meter to match the characteristics of the electrode in use.

A constant static position throughout the day can put your health at serious risk. An adjustable monitor stand for your desk allows you to change your body position throughout the day by altering the height and angle of the screen, offering a ‘second-best’ option to leaving your desk regularly to stretch. Get a monitor stand early to alleviate back, neck, and eye discomfort. If you don’t have any of these issues but use a monitor regularly, get a stand early; prevention is key in these cases.

From misting to spraying to fogging, customers have a wide range of cleaning tools at their disposal for delivering cleaners and disinfectants – but choosing the right delivery mechanism can be difficult. While disinfectants can simply be sprayed onto environmental surfaces to kill or inactivate pathogenic microorganisms, wiping the surface is an important part of the cleaning process and an effective way to control contamination on a hard surface.

If your baby doesn’t walk yet, they don’t really need hard-soled shoes to get around. Along with a Onesie and a pair of pants, socks with booties are all you need to stroll in the park, visit the store or have a bite to eat in your favorite restaurant. While you may be able to skip socks during summer, they’re an essential layer during most months of the year. This is especially true during winter when thick socks can prevent hypothermia and illness.
