I purchased a pH meter and So2 titrater about 10 years ago. Have called tech support for troubleshooting issues with the pH meter and followed up with online ordering of replacement parts (electrode and temperature probe). Great support and simple process.

Product is good however not packaged properly.

little confusion using website

Use your aquarium test kits and am very pleased with the ease of use and accuracy.

Love it! I recommended!!
