GDH 1 17 Digital Hygrometer Humidity Tester

The Bosch GDH 1-17 Professional is a digital thermo hygrometer designed for precise environmental monitoring on construction sites and in commercial buildings. It delivers real-time, minimum, and maximum readings across five key measurements: air temperature, relative humidity, dew point, wet bulb temperature, and absolute humidity. The 2.0" high-contrast colour TFT LCD display ensures readings remain clear and legible even in poor lighting conditions. Built for demanding job site use, the GDH 1-17 features rubber-reinforced housing and an IP65 rating, providing reliable protection against dust ingress and water splashes. A robust sensor protective cage adds further durability, while the centre button allows measurements to be held on screen for easy reference. The adjustable threshold scale allows users to configure relative humidity reference points to suit specific applications, making results quicker to interpret in the field. It is well suited to HVAC engineers, building technicians, energy consultants, carpenters, and facility managers assessing humidity conditions prior to works or ongoing monitoring. Supplied ready to use with two AA batteries and a protective pouch, the GDH 1-17 operates across a wide temperature range of -20°C to +50°C, making it a reliable choice for both indoor and outdoor environments.
