batteries and instructions.

Keep track of humidity and temperature levels in enclosed spaces with this mini hygrometer from Testo. This unit features a flexible measuring stick that lets you take readings from various angles for ease of use. Thanks to the broad operating temperature range of 0°C to +50°C, it's fit for use in harsh environments. Its humidity sensor measures the level of water vapour in the air across a relative humidity (RH) range of 5% to 95%, making it suitable for use in both dry and wet applications. You can also use this hygrometer to assess dew point for increased versatility.

• Robust battery life of 1000h for reliable, long-term use
• Light weight of 75g for portability
• Attachment clip for hands-free use
• Protective cap to prevent damage to the sensor

• Assembly plants
• Oil and gas industry
• Building maintenance

The dew point measures the temperature at which moisture in the air starts to condense, which can affect applications like piping and sensitive electrical systems. Knowing the dew point temperature lets you make necessary safety adjustments for applications that may be affected by water vapour.
