Testo 608-H1 Digital Hygrometer, ±3 %RH Accuracy, +50°C Max, 95%RH Max

Measure humidity and water vapour in the air with this digital hygrometer from Testo. The device continuously monitors both temperature and moisture percentage in the air, giving you more control in sensitive environments. It has a large LED (light-emitting diode) backlit display, making it easy to take readings in most lighting conditions. The device operates with a 9V block battery that provides a year of battery life for long-lasting use.

• Device self-stands on flat surfaces or mounts using the terminal at the back for versatile set-up
• Wide operating temperature range of 0°C to +50°C for use in a range of environments
• Accuracy of ±0.5°C and resolution of +0.1°C for precise temperature readings
• New reading provided every 18 seconds for continual sensing applications
• Tough ABS (acrylonitrile butadiene styrene) thermoplastic housing material resists impact damage and wear

• Garden centres
• Storerooms
• Cleanrooms
• Museums
• Laboratories

A hygrometer measures moisture in the air, whereas a moisture meter measures moisture inside a material.
