If you are searching for a ph meter, you need to find the best equipment for your application. After all, you’re investing your hard-earned money on this device. You want something that can provide the best measurement with precision and accuracy. Most of all, you want a durable product that can last for a long time. However, with so many different meters online, finding the best one can leave you overwhelmed and confused. Before spending a boatload of money, you must have a thorough understanding of where you will use it, along with the conditions involved. Based on where you will apply the device, you can make sound decisions on what features to prioritize. You may want to consider the following elements:
Check for Compatibility with Chemicals
When you’re checking out meters, remember that compatibility between the ph sensor materials and the chemicals you will be checking matters. Cheap polymer body probes should never be used for inorganic substances. If you need to check something highly corrosive, make sure that the equipment you buy can sustain the harsh environment. You need materials that do not degrade fast. At the same time, if you need it for handling heavy applications with a harder impact, you must ensure that the sensor material can withstand the pressure and resist breakage. You must ascertain that the electrodes of the equipment you’re buying are made of high quality.
Look at The Temperature Requirements
When you select a ph meter for any application, the materials used to make the sensors matter. It would be good if you considered the temperature you will use it for, chemicals it will check, and how you intend to handle it. In general, polymer equipment, including plastic, epoxy, or the like, can only be utilized for applications that require low to medium temp ranges. In higher temperatures above 100°celsius, it would be best to use glass. Moreover, to get an accurate reading, you need an advanced meter with auto temp compensation to allow for variations in your sample. Find one that permits calibration for better accuracy.
Assess The Calibration
All ph meters must be calibrated as this assures accuracy of reading results. Typically, calibration is achieved when testing with a ph buffer solution. It is best to purchase a meter that relies on at least a 2-point calibration so you can get as close to your expected results as possible. For best results, find something with an integrated sensor quality check that gives you peace of mind that you’re getting the right readings. Moreover, find a device that can provide you with a range of electrodes for whatever purpose you need.
Ask yourself where you will use your device? If you need it for the field, then a portable meter you can put in your pocket and hold with your hand will work best. You must also look for something that can withstand the elements if you take it outside. However, if you mostly use the meter in a lab setting, a benchtop meter is ideal. Though the price of this device is higher, you can count on its accuracy and longevity. Or better yet, for best results, find a convertible device. This means you can use this portable device and recharge it readily for field use. At the same time, you can use a stand plate and power supply to convert for benchtop use.
Check the Provider
Finally, do check the reputation of the provider. Do they provide high-quality products for a fair price? What do their clients say about the quality of their equipment? Apart from that, ascertain if they provide parts and labour. Should you encounter problems with your machine in the future, the company must be willing to assist you for much-needed services and repairs. You will be investing your money on a machine, so must go the extra mile to ensure you will receive a premium product from a reputable company that has been serving the industry for many years.
