Article Do third-party companies manufacture waterproof or water-resistant solutions for iButton data loggers?

Yes.  Here are some resources for making iButtonRegistered data loggers (Thermochrons) waterproof and/or using them in water or liquid monitoring applications:

  1. Maxim manufactures the DS9107 "iButton Capsule".  The iButtonRegistered Capsule is a mechanical enclosure to protect Temperature Logger iButtons (DS1921, DS1922, and DS1925 series) from moisture, solvents and pressure. It provides IP68 protection.  More info can be found here: https://www.analog.com/en/products/ds9107.html
  2. Homechip sells several waterproofing enclosures for iButton data loggers, including:  1 sinking silicon Thermochron enclosure, 1 floating silicon enclosure, and 1 aluminum half-enclosure:  https://homechip.com/search?type=product&q=data+logger+enclosure
  3. For Do-It-Yourself (DIY) waterproofing Thermochron solutions, there has been a published study on the efficacy of coating iButton devices with clear plastic dip: https://www.researchgate.net/publication/257160340_Does_waterproofing_Thermochron_iButton_dataloggers_influence_temperature_readings
