The world’s lightest and smallest multigas analyzer GT5000 Terra (9,4 kg including battery) knows what’s in the air. Easy to use and also wireless, it measures simultaneously over 50 gases in a few seconds. It is able to measure over 300 gases. GAISSA created the industrial design for the analyzer device.
HELSINKI, FINLAND – November, 8, 2019 - FTIR-Technology (Fourier Transform Infrared Spectroscopy) utilizing GT5000 Terra is a gas analyzer design for field conditions, that can identify and measure the gases in the air easily and reliably even in challenging circumstances. Using the stable built-in optics inside the device you can do the measuring in shaky conditions. The GT5000 Terra offers carefree and versatile use, furthermore it offers reliability regardless of the weather (IP54 class) and works in frosty conditions. Use temperature is -5 – 40 °C.
Thanks to its small size and durability the GT5000 Terra is capable of measuring the natural and harmful gases in the air in multiple applications. The device identifies toxic gases e.g. shipping containers, laboratories, production facilities, and accidents. The device is also great for natural greenhouse emissions outside. The device has a built-in pump and it can be added with additional parts for the needs of the usage and the customer.
GAISSA created completely the industrial design for the new multigas analyzer device and probe. The design started with the first ideas with close collaboration with the Gasmet product development team. The mechanical design of the casing was done with GAISSA Oulu based partnership company Optotec Group. The product was launched 24.10.2019.

|Weight without battery (kg)||12.4||8||-35.5%|
The product appearance of Gasmet devices was significantly updated in connection with the new device design. A robust and compact overall appearance was concentrated on. These parameters were well in line with the crucial target to create an analyzer device small and durable. During the product development also Gasmet updated its company visual identity and this was considered in the design of the device.
A significant improvement factor was the decision to let go of RIM cast parts of the casing, and create new solutions based on injection molded parts. The casing parts could thus be made smaller and more durable. At the same time, the precision was significantly improved and the thickness of the walls could be thinned. This also made it possible that a higher IP class (international protection) could be achieved.
In the conceptualization at the start of the project other big decisions when it comes to the whole, such as the layout of the components inside the device, quantity of the casing parts and the placing of the parting lines. By these decisions the layout model could be optimized, as well as serviceability features and use of the device could be improved.
The user often has to carry the device the last meters to the location of use. For carrying a fixed handle was designed, more comfortable than the previous version. For harness attachment, the casing parts were integrated with steel attachment points.
Because of high seal demands the cooling of the device is mainly through the integrated machined aluminum heat sink in the plastic upper casing.
The actual user interface was tried to keep as similar as possible to the previous device generation. By this, we tried to ensure that old users could operate the device without learning a new operating model. The device may also be used wirelessly.
Concrete results were wanted fast. From the beginning of conceptualization, almost all development material was realized in 3D. Working in 3D is slower than traditional sketching, but as you move on, it is overpowering in its precision and lessens the need for rework. Nowadays the rendering of 3D concept images is very fast. With the use of advanced images and 3D models rotating on screen, the stakeholders can have a clear picture of the solutions under development.
Early 3D working brought agility to handling the layout model and the layout of the components. Design concepts could be sketched straight based on alternative product structures. This way we could really fast to get on the right track towards an optimal solution.
The 3D working also brought new to the prerequisites to the assessment of the early production costs of the components. As soon as there starts to be 3D geometry of the part to be designed you can start the assessment of production costs. Naturally, in the beginning, you do not know the final quantity of the parts or their complexity. The estimated costs are getting more precise as the design goes on.
During the project, prototyping was an essential way to heighten the quality of the designed features and parts in every iteration round. In the initial stage, the measures and forms of the components were in practice scrutinized with rapid models. The mechanical design and design were conjoined more tightly as the device planning went on. Instead of rapid models’ series of PUR prototypes were made of the components. With PUR parts cast to a silicon mold, we could get rather close to final injection molded parts in quality and appearance. When the PUR parts were ready we could first time really assemble parts under design together and run various tests.
With modern product development methods, we could speed up the industrial design lead time, the evaluability of the development solutions was advanced, and we could bring more precision to the component cost estimates already from the beginning.
