The Isuzu TH27R (TH-27R) thermohygrograph is discontinued. For a replacement temperature and humidity chart recorder, choose the Sato NSII-Q (Sigma II).
The Isuzu TH27R thermohygrograph has been discontinued. This page remains available for customers identifying an existing TH27R or TH-27R recorder and planning its replacement.
For continued temperature and humidity recording on paper, our recommended replacement is the Sato NSII-Q (Sigma II) thermohygrograph.

Previous Isuzu TH27R model, shown for identification.
The NSII-Q records temperature and relative humidity on a paper chart, with a quartz-driven drum selectable for 1-day, 7-day or 32-day rotation. Select the temperature range that covers your normal conditions and expected variations.
| Replacement model | Temperature range | Humidity range | Chart rotation |
|---|---|---|---|
| Sato NSII-Q 7210-00 | -15 to 40°C | 0 to 100% RH, non-condensing | 1, 7 or 32 days |
| Sato NSII-Q 7211-00 | -10 to 50°C | 0 to 100% RH, non-condensing | 1, 7 or 32 days |
The NSII-Q is an alternative from Sato. Confirm its specifications against your application rather than assuming that every TH27R feature or accessory is identical.
Existing TH27R paper and pens should not be assumed interchangeable with NSII-Q consumables. Use the chart and pen references listed for the selected Sato recorder.
| Requirement | Information to provide |
|---|---|
| Charts for an existing TH27R | Chart part number, temperature and humidity scales, recording period, and a photograph of the current sheet |
| Pens for an existing TH27R | Pen reference, colour and a photograph of the fitted cartridge |
| Consumables for a new NSII-Q | Selected recorder model, chart period and required quantity |
For existing Isuzu TH27R thermohygrographs, the consumable references below are retained from our previous listing. Please confirm compatibility and availability before ordering.
| Consumable | Listed reference | Details |
|---|---|---|
| 7-day chart paper | 20012-7 | Temperature scale: -20 to 50°C. Humidity scale: 0 to 100% RH. Pack: 55 sheets per box. |
| 32-day chart paper | 20012-31 | Temperature scale: -10 to 50°C. Humidity scale: 0 to 100% RH. Pack: 15 sheets per box. |
| Violet cartridge pens | 7210-90 / 7238-04 / 7238-02 (12-piece pack) |
Violet recording ink. |
| Red cartridge pens | 7210-92 / 7238-08 / 7238-06 (12-piece pack) |
Red recording ink. |
Before ordering: Send the recorder model, a photograph of the existing chart or pen, and the required quantity. Chart paper must match the recorder's scale and drum rotation period. The references above should not be assumed interchangeable with each other or with consumables for the Sato NSII-Q replacement.
Contact us for replacement pricing and availability. Include your existing TH27R nameplate or chart photograph, required measuring range and quantity.

The Isuzu TH27R (TH-27R) thermohygrograph is discontinued. For a replacement temperature and humidity chart recorder, choose the Sato NSII-Q (Sigma II).
The Sato SK-L200THIIα temperature and humidity datalogger is discontinued and has been replaced by the Sato SK-L750 series. For recording both temperature and relative humidity, select the SK-L754 with a suitable probe.
The Sekonic ST-50A digital thermohygrograph combines an electronic temperature and humidity display with continuous paper chart recording. View current conditions and retain a physical record for environmental checks.
Discontinued model: Manufacturer sales have ended. Remaining stock, consumables and alternative instruments are subject to availability.
Sekonic Universal 6 channel Recorder SP-100 / SP100 records from different sources simultaneously, including mA, V, PT100, Thermocouple.
Dickson circular chart recorders provide a paper record of temperature, humidity, pressure or external transmitter signals, depending on the model. Select the recorder by measurement type, chart size, recording period and installation requirements.
The Dickson TWP touchscreen data logger displays readings and measurement history on an 8-inch colour screen. Configure it for temperature, humidity or differential pressure monitoring using compatible replaceable sensors.
The Sato NSII-Q Sigma II thermohygrograph records temperature and relative humidity together on a rotating paper chart. Its quartz-driven mechanism provides a visible measurement history for routine environmental checks.
The Sato SK-L750 series data loggers record temperature or temperature and humidity for later review on a PC. Choose the SK-L751 for two-channel temperature measurement or the SK-L754 for combined temperature and humidity recording.
Monitor four measurement points with the Sato SK-L400T 4-channel temperature data logger. Connect Type K thermocouple probes, view all four readings together and record temperature data to an SD card.
Monnit ALTA® Wireless Thermocouple Sensors leverage Monnit’s award-winning remote monitoring platform to remotely monitor high-temperature applications, such as commercial ovens, kilns, and chimneys. Users benefit from a wireless data transmission range of 1,200+ ft, bank-grade security, and a temperature range of up to 400°C (752°F).
Monnit’s thermocouple is user-programmed to sleep for a specified interval, awake, capture analog data, and then convert this measurement into a temperature. If the sensor captures temperatures outside of user-specified thresholds, an alert is sent via text, email, or call. Monnit’s hardwired thermocouples feature a needle-style probe at the end of a 6’ lead (a K-Type Quick Connect Thermocouple is also available).
The Sato SK-RHC-I temperature and humidity transmitter combines a local display with 4–20 mA outputs for connection to compatible monitoring and control equipment. Three interchangeable probe designs support different sensor positions.
Probe sold separately. An optional AC adapter is available.
Monnit ALTA Wireless Humidity (RH) Sensor allows you to accurately monitor the relative humidity of the air within a room or enclosure. - Measures relative humidity, temp
Palmer Wahl pressure and temperature chart recorders provide a paper record of measurements over time. Choose an 8-inch or 12-inch recorder with an aluminium or Pelican® case, configured for pressure, temperature or combined recording.
The Sekonic ST-50M thermohygrograph records temperature and relative humidity on paper charts and an SD memory card. Its digital display provides local readings, while recorded electronic data can be reviewed on a computer.
