The attractive and compact testo 608 thermal hygrometer is for continuous indoor climate monitoring (humidity, temperature, dew point). The LCD display is legible at distance. The testo 608 models have a max/min value display and a battery monitor. Suspension and standing fixtures allow flexible positioning on a table or wall. Version 608-H2 is the higher accuracy model which also comes with a precise alarm. The 608-H2 alarm reports if humidity and temperature limits are exceeded in building developments and installations ranging from garden centres to museums, storerooms, laboratories and cleanrooms.

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.
