DIAGRAMS
FOR RECORDER THERMOMETER & HYGROMETER

Thermographs and hygrographs continuously record variations in temperature or humidity on a paper chart wound around their cylinder. These charts are sold in packs of 100 sheets and are specially manufactured to ensure a clear, precise, and durable recording.

The paper used has been selected to work perfectly with NAUDET pens. Its composition allows for excellent ink absorption, without smudging or spreading, to obtain a fine and perfectly legible line.

To choose the right chart for your device, simply follow these three steps:

• Choose the height of your recording cylinder: 9 cm, 12.5 cm, or 13.5 cm.
• Select the graduation corresponding to your device, for example, 20 to 100% humidity or the temperature range indicated on your thermograph.
• Finally, choose the chart reference indicated in your manual or on your old chart.

If in doubt, our workshop is at your disposal to help you identify the correct reference for your thermograph or hygrograph, regardless of its brand or age.
