Sato Mini-Cube 7008-00 compact thermohygrograph for continuous 7-day recording of temperature and relative humidity.
The Sato Mini-Cube 7008-00 is a compact mechanical thermohygrograph for simultaneous recording of temperature and relative humidity.
A rotating 7-day chart provides a continuous visual record of environmental conditions without requiring a computer, network connection or external power supply.
Its compact enclosure makes the Mini-Cube suitable for locations where a full-size thermohygrograph would take up too much space.
The Mini-Cube records temperature and relative humidity simultaneously on the same rotating chart.
Temperature is measured using an aged bimetal sensing element, while relative humidity is measured with a human-hair bundle. Two cartridge pens trace the measurements continuously as the chart drum rotates.

SATO specifies approximately six months of battery operation and drum rotation accuracy of about ±1 hour over seven days. :contentReference[oaicite:1]{index=1}
| Measurement | Condition | Accuracy |
|---|---|---|
| Temperature | 10°C to 30°C | ±2°C |

| Relative Humidity | Outside the above conditions | ±7%RH |
These are the manufacturer-published accuracy specifications for the Mini-Cube. :contentReference[oaicite:2]{index=2}
The quartz-driven drum completes one rotation every seven days. This gives a continuous week-long record of both temperature and relative humidity.
The chart can be reviewed directly without downloading data or using software, making the Mini-Cube suitable where a simple permanent paper record is preferred.
One box of 55 seven-day charts is included, providing approximately one year of weekly chart recording.
Replacement chart paper and recording pens are available for routine operation of the Mini-Cube.
| Part Number | Description |
|---|---|
| 7008-62 | 7-day chart paper, 55 sheets per pack |
| 7210-90 | Violet cartridge pen |
| 7238-02 | Violet cartridge pens, box of 12 |
| 7210-92 | Red cartridge pen |
| 7238-06 | Red cartridge pens, box of 12 |
The current SL page also references additional legacy packaging numbers for replacement pens, while SATO's current Mini-Cube manual lists 7210-90, 7238-02, 7210-92 and 7238-06. :contentReference[oaicite:3]{index=3}
The Mini-Cube requires no data logger software, memory card or network connection. Temperature and humidity are recorded mechanically onto chart paper using the quartz-driven drum and cartridge pens.
This makes the instrument useful where staff need to see environmental history immediately from the chart rather than opening recorded data on a computer.
Place the Mini-Cube where air can circulate freely around the instrument. Do not cover the ventilation openings.
Avoid installation in direct sunlight, close to heating equipment or in locations exposed to heavy dust, soot or corrosive gases. For outdoor measurements, SATO specifies that the unit should be installed inside a suitable instrument screen. :contentReference[oaicite:4]{index=4}
The Mini-Cube is not explosion-proof and should not be used in environments containing flammable gases. :contentReference[oaicite:5]{index=5}
The chart is normally changed once every seven days. Fit the replacement chart correctly around the drum and align it according to the required starting date and time before returning the recording pens to the chart.
Use chart reference 7008-62 for the Mini-Cube 7-day recording cycle.
The Mini-Cube uses replaceable cartridge pens. Replace a pen when the trace becomes faint, irregular or incomplete.
Violet is the standard recording-pen colour. Red replacement pens are also available where a different trace colour is required.
Confirm that the required measurement conditions fall within:
For applications requiring electronic data storage, alarms, remote monitoring or selectable recording intervals, a digital recorder or data logger may be more appropriate than a mechanical thermohygrograph.
