Humidity standards

Although most relative humidity (RH) probes have excellent long-term stability, it is recommended that their calibration be checked regularly.

• Traceable to national standard – SCS (Swiss Calibration Service) certificate included
• Ampoules contain unsaturated salt solutions (~0,8 ml)
• Inexpensive on-site calibration
• Simple and safe to use
• 10 year shelf life
• Practical packs of five ampoules of the same humidity value

 : Each ampoule is labelled with the humidity value and serial number.

 : Values and accuracy (measurement uncertainty values) below are measured at 23 °C.
