Summary for decision-makers

Bosch Professional is expanding its range of measuring instruments with the launch of new humidity and temperature detection tools tailored to the needs of professionals in the building, HVAC, energy, and maintenance sectors. The GDH 1-17 Professional (thermo-hygrometer), GMM 1-15 Professional (pinless moisture meter), GMP 1-13 and GMP 2-15 Professional (pin moisture meters), and the GLM 40-31 Professional laser rangefinder offer robustness, ergonomics, high precision, and a wide measuring range, even in extreme conditions.

These devices are distinguished by their dual power supply, IP65 protection rating against water and dust, intuitive interfaces, and advanced features such as measurement memory, customizable thresholds, and automatic calibration. They facilitate a variety of applications: humidity and temperature control, mold prevention, building inspection, and distance calculations, promoting autonomy, speed, and reliability on site.


High humidity levels in a building can compromise the integrity of its structure or cause significant damage to building materials (wood rot, cracking or crumbling walls, corrosion of metal elements, etc.). Measuring the humidity level of materials is an important step in preventing risks or limiting damage.

Robust, precise, intuitive and easy to interpret

Bosch Professional is launching a new segment in its measuring instrument portfolio with humidity and temperature measurement tools. The GDH 1-17 Professional thermo-hygrometer, the GMM 1-15 Professional pinless moisture meter, and the GMP 1-13 Professional and GMP 2-15 Professional pin-type moisture meters are distinguished by their ergonomic and robust design, precision, and large measuring range. Combined with the new GLM 40-31 Professional laser distance meter, they can meet a wide range of applications, even under extreme conditions.
To work with greater autonomy and flexibility, they have the Dual Power dual power supply to operate with a Lithium-Ion BA 3.7V 1.0Ah A battery or 2 AA LR6 batteries.

New: GDH 1-17 Professional Thermo-Hygrometer

The robust humidity and temperature tester for demanding construction sites


With the new Bosch GDH 1-17 thermo-hygrometer, architects, energy consultants, plumbers, HVAC professionals, building inspectors and carpenters can quickly measure temperature (-20°C to +50°C) and humidity (5% to 95% RH) levels in the air. 

Monitoring air humidity levels in storage areas or in a room, identifying the degree of humidity to assess the energy efficiency of a building, checking the performance of HVAC systems, identifying areas with high humidity in the air... is very easy with the GDH 1-17 Professional.

It monitors in real time and with high precision the min/max values ​​of 5 key temperature variables:

  • air temperature,
  • the relative humidity level,
  • the dew point,
  • wet bulb temperature,
  • the absolute humidity level.

For easy reading of relative humidity results, the GDH 1-17 Professional features a user-adjustable variable threshold scale (green and red).

Robust and durable, the GDH 1-17 Professional is designed for demanding construction sites. Its rubber-reinforced housing with an IP65 rating ensures good protection against water and dust. An IP65-rated, breathable, waterproof protective membrane protects the sensor from harsh conditions while maintaining accuracy and performance. 

The ergonomic GDH 1-17 Professional offers a comfortable and secure grip thanks to its soft grip and its particularly intuitive user interface. Its high-contrast color LCD display makes readings easy, even in low light, and its 3-button keypad - start/stop/back button, settings button and central button for navigating and holding measurements - simplify its use.


New: GMM 1-15 Professional Pinless Moisture Meter

To quickly check the moisture content in wood and building materials

A valuable aid for plasterers, painters, architects, plumbers, carpenters, etc., the new Bosch Professional GMM 1-15 pinless moisture meter inspects surfaces to detect possible water damage, locate hidden leaks, measure the moisture content of drywall, concrete, masonry, check the moisture level of wood, areas that could generate mold, etc.

With its non-invasive material sensor, it can monitor and measure the moisture content of 37 wood species and 10 building materials. The adjustable variable threshold scale with a color display allows for quick interpretation of results. 
Reference mode allows you to compare humidity levels in different locations to a dry reference area.

With its compact and ergonomic design, the GMM 1-15 Professional is easy to use and comfortable to hold. Its high-contrast color LCD display ensures better visibility of results. Its intuitive interface features a start/stop/back button, a settings button, and a center button to hold the display for easy recording and analysis of data. An adjustable beep emitted at each measurement confirms the measurement. 

Robustly designed, the GMM 1-15 Professional remains reliable in even the harshest construction site conditions. Its rubberized casing and IP65 protection rating ensure good sealing against water and dust, and high durability.

 

New: GMP 1-13 Professional / GMP 2-15 Professional Pin Moisture Meters

A wide measuring range for accurate results

For professionals who want to take quick and accurate measurements of humidity levels, the new Bosch Professional GMP 1-13 and Professional GMP 2-15 pin moisture meters are ideal. They reliably identify sources of moisture that cause mold or water damage, and assess the moisture content of materials such as wood, drywall, plaster, or concrete to ensure optimal conditions during work (painting, wallpapering, parquet flooring, etc.). 

By inserting the two pins into the materials, the user can take measurements from -20°C to 50°C, in 37 wood species and 10 building materials.

The GMP 1-13 Professional and GMP 2-15 Professional have an adjustable variable threshold scale that facilitates the interpretation of measurements according to user preferences. 
An automatic/manual self-test verifies the calibration before each use to ensure accurate results.

The GMP 2-15 Professional has a thermo-hygrometer sensor to monitor ambient temperature and relative humidity, and thus ensure the quality and longevity of the materials.

Durable and highly robust, the GMP 1-13 Professional and GMP 2-15 Professional are designed to withstand the harshest construction site conditions. Their reinforced rubber housing with an IP65 rating guarantees protection against water and dust.

Compact and functional, these pin-type moisture meters offer a comfortable grip with their knurled (TPE) coated handle. They are easy to use, thanks to their particularly intuitive interface, their high-contrast color LCD screen that optimizes the readability of measurements, their start/stop/back and settings buttons.
