Milwaukee MC122 Manual

CARE AND USE

pH meters usually start performing poorly because of problems with the probe, specifically the glass sensing bulb and the reference junction.  The glass bulb loses sensitivity with use and will eventually fail, which is true of all pH probes.  The reference junction is a small hole that allows the meter to compare the sample to a reference.  If the junction hole gets clogged, the pH probe will no longer function.

The life of your pH electrode can be extended in the following ways:

  1. Storage - The pH probe needs to be kept hydrated. Long periods of dry storage will damage the sensitivity of the probe. Allowing the probe to dry out may also result in the junction hole getting clogged. Storing in pH probe storage solution or pH calibration buffers will help address both these issues. Do not store in tap water and DI water, this will damage the sensitivity of the probe.  The best way to store the probe is with the probe's cap filled with storage solution or calibration buffer and the cap tightened to prevent leakage. It is also recommended to store the electrode upright to further reduce the potential for leakage.
  2. Cleaning - Residue from the sample can impact the sensitivity of the sensing bulb and clog the junction. This is especially true if the sample has a lot of organic material. It is recommended to regularly soak your electrode in cleaning solution.
  3. Calibration - The pH sensing bulbs become less sensitive over time so make sure that you are calibrating regularly to keep your PRO pH meter accurate. Also, calibrate after cleaning or a long period of storage.

        A Safer, Delicious Alternative to Rawhide
        Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
        If you are looking for a safer alternative to traditional rawhide, the DreamBone Twist Sticks are a fantastic choice. These chews offer all the engagement of a classic chew but are 100% rawhide-free, making them much easier for dogs to digest while still being highly satisfying. The taste is clearly a winner, as they are made with real chicken and wholesome vegetables. Dogs find the flavor irresistible, and the unique twist shape adds an extra layer of fun to their treat time. They don't smell bad as I am removing them from the package. (PLUS FOR ME) I buy these often for my pups, a Milky and Silky, and they can chew them easily without any digestive issues. The treats come out of the package soft and not dry. They are definitely durable enough for my two small pups, but they break up easily with their little mouths. Why these chews are a great addition to your pet's routine: Dental Health Support: The natural action of chewing helps maintain healthy teeth and gums by reducing plaque and tartar buildup. Nutrient-Rich: These treats are enriched with vitamins and minerals, providing extra nutrition alongside a "scrumptious" taste. Wholesome Ingredients: By combining real meat with vegetables, these provide a high-value reward without the risks associated with rawhide. Highly Digestible: Because they are rawhide-free, they are gentle on the stomach and perfect for everyday treats. These are a practical, healthy, and delicious way to reward your dog while supporting their overall hygiene.

        They are highly preferred by our pet!
        Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
        Our dog absolutely dream bone twist sticks! They have a very pleasant scent and are the perfect softness. He gets one in the morning with a few other small treats and always saves this for last we think it’s because it’s the favorite. This is not made of rawhide in therefore highly digestible. Perfect size for a medium to small dog; would not recommend for a larger dogs due to choking. You can, however, get larger bones in the same brand. With 50 in a bag, you can purchase them less often. They are highly preferred by our pet.

        Great For Puppy to Elderly Dogs
        Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
        All 3 of our dogs love this treat, We like that the treats are free of rawhide. They are soft enough for even our 15 year old dog to enjoy. The treats can easily be cut into pieces to use as training treats or to hide in dog puzzle toys. With 50 sticks per bag, we don't run out of them too soon.

        Good Treats, But Too Small for Large Dogs
        Flavor Name: Chicken, Size: 9.7 Ounce (Pack of 1)
        I purchased these DreamBone Twist Sticks for my large dogs. They had no problem eating them, but the treats were much smaller than I expected for bigger breeds. Because of the size, they didn't last very long and weren't as exciting for them as some of the other chews I've purchased. That said, the dogs did eat them, and the quality seemed good. My dogs can be pretty picky, so their lack of enthusiasm may have had more to do with their preferences than the product itself. I think these would be a great option for small or medium-sized dogs, or as a quick treat rather than a long-lasting chew. Overall, a decent product, just not the best fit for my large dogs.
