Gasmet reduces size of GT5000 Terra multigas analyzer

Gasmet says its GT5000 Terra multigas analyzer is the world’s smallest portable analyzer designed for demanding conditions.

The unit, which weighs 20.7 pounds with a battery installed, can be operated wirelessly for measuring up to 50 gases simultaneously in a matter of seconds, the Finnish manufacturer said, and is capable of identifying more than 300 gases.

The GT5000 Terra gas analyzer for field use utilizes Fourier-transform infrared spectroscopy (FTIR) technology that allows the machine to identify and measure airborne gases in the demanding conditions with an “innovative, highly integrated” optical structure, Gasmet said, with the number of moving parts minimized to maximize stability.

And as the GT5000 Terra is IP54-rated, it is suitable for versatile outdoor use in any weather—even subfreezing temperatures, the company maintained.

The compact analyzer can be used for measuring natural and harmful airborne gases in numerous applications. It can identify toxic gasses in containers, laboratories, production facilities and accident sites, or measure natural greenhouse emissions in outdoor environments.

The device comes equipped with an integrated pump and internal battery, and can be modified with optional accessories according to the application or client’s needs, Gasmet said.

“As a response to users’ wishes, we reduced the gas analyzer’s size to a minimum and invested in user-friendliness without compromising performance,” said Anna Leino, product engineer at Gasmet. “The analyzer’s wireless functions are particularly useful in hazardous or uncomfortable conditions as the analyzer can be controlled remotely from a safe distance.”

Gasmet claims the GT5000 Terra is easy to setup and measurement is initiated with the press of a button. The updated Calcmet Easy software can be run on a tablet, enabling easier interpretation of results on site. The device and the software were designed to be used with minimal training, and the tablet’s touch screen can be used while wearing protective gloves.

“The software guides the user in making analyses and warns if the sample contains too high concentrations of, for example, hazardous gases, or if the sample contains unknown components,” Leino said.


Key features of the GT5000 Terra, according to Gasmet, include:

  • The world’s lightest and smallest portable multigas analyzer (9.4 kg with battery)
  • Weather-proof, IP54 rated
  • Measures up to 50 gases simultaneously using FTIR technology, and recognizes more than 300 gases.
