The standardization of a pH meter is important to ensure that the readings returned from that meter are accurate. Digital & analog pH meters offer calibration buttons or dials that are used to adjust the sensitivity of the meter. Over the course of standard usage, laboratory equipment, such as...

What is acidity? What does pH actually mean? How does a pH meter work? Who invented the pH meter? Find out moreWhat is acidity?Photo: Some acids, such as lemon juice, are perfectly safe to handle; others will burn your skin and can do painful, permanent damage. How can you tell whi...
These probes use a reference and test electrode to relate the ion activity between the sample and the reference to produce a measurable, but small, voltage. With calibration, this voltage measurement directly correlates with a pH value. To be thorough, neutral 7 on the pH scale should have a...
The glass electrode was invented by Nobel Prize winner Fritz Haber in 1909, followed by the development of the modern electric pH meter in 1934 by Arnold Beckman, giving birth to pH probes that we use now to accurately measure pH in a variety of applications. pH (the potential of Hydrogen...
A calibration confirmation will be displayed at the bottom of the pen or meter screen to indicate a successful calibration. It will disappear after 30 days to indicate calibration is required. Having trouble with calibration or is the pH pen showing an error code? Read ourtroubleshooting and erro...
4. Getting Your pH Meter Right Consistent and accurate pH readings start with a well-calibrated pH meter. Here’s how you can ensure your pH meter is giving you the real deal: Warm it up: Turn on your pH meter about 30 minutes before use. ...
Issue: What is Power Factor Correction (PFC) - Does it help conserve energy? Answer: Explanation 1: Power Factor Correction (PFC) doesn't directly reduce the overall electric consumption of a device or system, but it does play a role in optimizing the efficiency of electrical systems, which...
There are a few different ways to measure in solution, with the quickest being a handheld pH pen or probe. Alternatively, you can also send samples to a laboratory or use testing strips. Here’s where you should think about measuring your solution pH and the benefits of each location. In...
Press "Set" on the main interface to enter the menu, select "Running parameters" through the arrow keys, and then press "Set" to enter the editing interface. After each parameter is modified, it will automatically switch to the next parameter. If the working group is set to this group, ...
