Bosch PRO GDH 1-17 Thermo Hygrometer
Accurate climate monitoring helps professionals make informed decisions on site. The Bosch PRO GDH 1-17 Thermo Hygrometer measures key environmental values in real time, giving clear readings for temperature and humidity. As a result, users can quickly assess conditions in buildings, storage areas, or renovation projects.
Clear information is displayed on a bright 2.0 inch TFT LCD screen. The colour display offers a resolution of 240 by 320 pixels, which helps readings remain visible even in poor lighting. In addition, the Bosch PRO GDH 1-17 Thermo Hygrometer records minimum and maximum values so users can track changes over time.
Reliable environmental measurements
Reliable measurement data supports safe building work and accurate inspections. This device measures relative humidity between 5 percent and 95 percent RH while also monitoring air temperature from -20°C to +50°C. Therefore, professionals can quickly identify moisture problems, temperature variation, and air quality conditions.
Furthermore, the device calculates several climate indicators including dew point, wet bulb temperature, and absolute humidity. These readings provide deeper insight into indoor environments and help guide maintenance or construction decisions.
Built for professional job sites
Durability is important when working in demanding environments. Bosch PRO GDH 1-17 Thermo Hygrometer features a rubber reinforced housing that protects the internal sensors. The IP65 rating adds protection against dust and splashing water, which makes the device suitable for job site conditions.
Comfortable operation is also supported by the compact handheld design. The centre button allows measurements to be held for quick review, while the device runs on two AA batteries for dependable power during daily work.
