Price range: See on Amazon

What we liked

  • + 250 ML size fits typical triple scale hydrometers
  • + Graduated markings help measure small liquid additions
  • + Affordable replacement for a broken test jar

Trade-offs

  • - Lesser-known brand with limited detail on material thickness
  • - Sample volume is fairly large, which wastes more wort per reading
