Replacing an Isuzu TH27R Thermohygrograph?
The Isuzu TH27R (TH-27R) recorded temperature and relative humidity on a rotating paper chart. The instrument has been discontinued, but you can continue paper chart recording with a Sato Sigma II / NSII-Q thermohygrograph.

Both Sato models record temperature and humidity on paper and offer selectable 1-day, 7-day or 32-day chart rotation. Choose chart paper for the exact Sato model and recording period. Check the measuring range and installation space before replacing an existing TH27R; the Sato recorder and its consumables should not be assumed identical to the Isuzu instrument.
Still Using a TH27R?
You can still buy consumables for your existing recorder. Check the reference printed on your current chart and the colour and shape of the fitted pen before ordering.
