Nickel Alert (dmg spot test) tests for nickel in any metal item such as jewelry, watches, and belt buckles. Nickel Alert is sensitive enough to detect the presence of free nickel at a level as low as 10 ppm (parts/million)—a threshold below which only individuals with the most pronounced sensitivity to nickel would experience a reaction.
Within 30 seconds you will know if the item has even minute amounts of nickel. One bottle of Nickel Alert is sufficient for 100 - 150 positive tests.
Nickel Guard™ is designed to coat jewelry and other metal items to protect you from nickel contact.
Nickel Guard forms an invisible micro-bond barrier effectively sealing the metal item so your skin does not come in contact with the nickel.
Nickel Guard is designed for persons with sensitive skin in mind and does not contain several ingredients which often cause secondary dermatitis. Ordinary nail polish may contain Toluene, Formaldehyde or Dibutyl phthalate which can cause secondary rashes. Nickel Guard does not contain these allergy causing ingredients.
Nickel Guard also works with Nickel Alert. Once an item is protected with Nickel Guard, it can be re-tested with Nickel Alert to verify protection.
