Meter Oscilloscope
Discover Where To Look For The Best ORP Meter Information}
ORP, or oxidation-reduction is a measure of the ability of a chemical to oxidize and reduce its concentration. It oxidizes with the chemical reaction of oxygen. The ORP Meter meter can measure this reaction potential. Anyone who works in the pool and spa industry uses an ORP meter regularly. Small pools and hot tubs may not always require this type of meter. But for public swimming establishments, the health and safety of the swimmers is of utmost importance. Therefore, the use of an ORP meter, along with the use of other instruments such as a ph analyzer, is essential.
There are two separate electrodes on an ORP meter. One electrode is generally made of silver, and is surrounded by an electrolyte solution. This probe produces a consistent voltage. That way, it can provide a reference to which the other probe can be compared. The second electrode is platinum and it provides the comparison measurement.
The difference of these measurements is what the ORP meter displays. Varying ph levels make it important to use a ph analyzer along with the ORP meter to ensure that the varying ph doesn’t effect the ORP.Of course, an ORP meter is essential to any public swimming facility. Health standards are very strict at public pools, and those who maintain these facilities must keep the ORP and ph levels at very specific ranges.Since health codes are so rigid with public facilities, a pool can be shut down if the ORP and ph levels aren’t at a healthy level. Failure to do so could result in either a hazardous amount of chemicals in the water, or the growth of invasive plants and bacteria.
Regardless, the ORP meter isn’t just manufactured for public swimming. Fish farms and other water based agriculture typically use an ORP meter to ensure the health of their livestock. In some industries, algae is grown for various purposes. It takes an exact type of water for algae to grow to their potential. Without an ORP meter to determine the proper water conditions, invasive species can emerge and threaten the algae.
The HI 9125N is a $350 ORP meter made by Hanna Instruments. Along with the ORP reading, the dual level LCD display also shows the ph level and the water temperature. It also has a power failure protection system. The ORP meter will shut off when the battery is too low to provide accurate readings. This assures the user that the results will never be inaccurate.
Extech makes a less expensive and smaller version of the ORP meter. The RE300 sells for roughly $110, and provides automatic self calibration electronically. This meter has a display that includes an easy to read bar graph.
Normal glass bulb electrodes are brittle, but this meter has a durable flat electrode design. You can take up to 15 different samples of data before the RE300 runs out of memory.With all of the benefits is provides, it is no wonder that public pools and fish farmers alike find the ORP meter to be absolutely essential in their careers.
