Testo 623 Digital Hygrometer, ±2 %RH, ±3 %RH Accuracy, +60°C Max, 100%RH Max

Use this thermohygrometer from Testo to keep track of temperature and humidity in your environment. The sensitive NTC (negative temperature coefficient) sensor uses changes in resistance to detect changes in temperature, enabling precise temperature measurement across a broad range of -10°C to +60°C. Its relative humidity (RH) measurement range of 0% to 100% means it'll accurately measure water vapour levels in both dry and wet applications. A large display shows both the current data and a graph of past data from the past 90 days. This lets you assess data trends at a glance for quick and convenient analysis.

• ABS (acrylonitrile butadiene styrene) case for durability and impact resistance
• Loud alarm for quick notification in emergency situations
• Quick 20s measuring rate for fast results
• IP30 (ingress protection) rating for protection against objects larger than 2.5mm in size
• Long battery life of 12 months for reliable performance

• Office buildings
• Construction industry
• Factories

This unit comes with a hanging and standing bracket that lets you mount the thermohygrometer on a table, desk or wall for convenient, hands-free use.
