Isuzu TH27R Thermohygrograph Support and Replacement
The Isuzu TH27R paper thermohygrograph is discontinued and is no longer recommended for new installations. Seacom continues to help customers maintain existing recorders by checking selected Isuzu chart papers and recording pens against the recorder and existing consumable references.
For customers requiring a new paper temperature-and-humidity recorder, Seacom can compare the current Sato Sigma II NSII-Q. It performs the same basic recording function, but it is not a direct drop-in replacement and uses different chart papers and pens.
