Field ready...
wear it!
Introducing K5, the 4 generation of the most popular wearable
metabolic system, a breakthrough in the field of exercise physiology and
human performance assessment.
1987 ... introducing K2, the first compact Metabolic
system (O2 consumption) for field testing
1994 ... introducing K4, the first mobile metabolic
system (both O2 and CO2) with patented
dynamic mixing chamber
1997 ... introducing K4 b², the first “breath by breath”
mobile metabolic system with integrated GPS
2014 ... K5 wear it!
It has been almost 30 years since COSMED
introduced the first generation of compact
metabolic systems. During this time we have
collected significant feedback and ideas
directly from the most important institutions
around the world.
The result of such an experience has been
carefully implemented in a complete new
piece of technology incorporating latest
design and providing researchers, sport
professionals and clinical users new ways to
explore human exercise physiology.
by breath mode depending on the protocol
type, research or other factors.
K5 features proven and reliable, highly linear
and rapid response O2 (GFC) and CO2 (NDIR)
sensors. The O2 sensor has an average lifespan
of 12 months. Once exhausted, the O2 cell
is replaced by the user without the need of
technical assistance.
K5 is also provided with a new function for a
rapid automatic-verification (“Check”) of the
main hardware components (sensors status,
response time, humidity, pneumatics etc.).
With this, users can quickly perform a quality
control of the whole system before starting
or even while the test is running.
Mix & BxB
Dual Metabolic Sampling Technology
COSMED is proud to introduce K5, the 4
generation of the most popular wearable
metabolic system, a breakthrough in the field
of exercise physiology and human performance assessment.
The K5 is the most innovative and versatile
metabolic system ever created. K5 reaps the
benefits of more than 25 years of experience
with metabolic systems. K5 features a list of
new and unique characteristics that expand
the scope of metabolic testing from clinical
exercise testing to performance assessment.
Accuracy & Reliability
4,5” (114 mm)
K5 has been designed with a focus on accuracy and usability. With this new generation
of metabolic system COSMED introduces
new patented technologies for gas exchange
IntelliMET™ (Intelligent Dual Metabolic Sampling Technology
- US Patent 9581539) sets a new standard in meta-
bolic measurements by providing a dual
gas sampling system able to provide both
micro-dynamic mixing chamber and breath
by breath gas exchange measurements.
With IntelliMET (option) users can select
between the mixing chamber and the breath
2,5” (64 mm)
6,8” (174 mm)
Designed according to IP54 standard,
K5 is a tough/rugged device. Rubber
seals protect the body, connectors and
ports against water, moisture and dust
Single-body device (battery inside),
reduces weight (780 g), thus simplifying
3,5’’ LCD (TFT transflective, LED-backlit).
The resistive touch-screen allows full
interaction with gloves or wet fingers.
4 keys waterproof keyboard for rapid
access to frequent functions (On/Off
and Rec buttons). Back/Check and
Home/Marker keys.
Li-ion “smart battery” (w/ microprocessor) with an LCD showing charge
status. Battery life is a total of 4 hours.
Batteries are easily replaceable.
Two large compartments located on the
top of K5 allow users to access the O2
sensor (user replaceable), the battery
and the SD-card slot (for extra storage
Tripod mount (1/4”-20 UNC) located at
the bottom of the unit allows mounting
on several standard supports.
Great attention has been paid to simplify
subject setup and improve ergonomics. The
preferred position of the device is mounted
on the back of the subject.
New harness design (2 sizes) provides
great comfort and ergonomics during
dynamic field testing.
The “standard” harness consists in 2
pieces; the “skeleton” is a robust/rigid/
rugged part adjustable in length (fits
height ranges from 160 to 200 cm circa).
The soft piece is made in neoprene,
detachable and washable, providing
great comfort while walking or running.
All plugs, connectors and caps are protected by seals
and are water, moisture and dust resistant
The 3,5” LCD is transflective with backlit TFT for optimal viewing in all lighting conditions
Optional paediatric harness has the
same features of the standard one and
fits subjects with height range between
120 and 160 cm.
User replaceable O2 sensor and/or battery is an easy
operation without any special tools
The integrated tripod mount (1/4”-20
UNC) provides extreme versatility and
acts as a safety support in case K5 is
mounted on supports available for
other wearable technology (i.e. for
biking or other outdoor activities and
sports) or when used in lab testing.
Accessing the SD-card slot is useful to simplify data
sharing without connecting to the PC software
K5 complies with IP54 standard, it has been specifically designed for
outdoor use and provides protection against heavy water (rain, sweat) or dust.

data and/or connected devices (ANT+
The K5 features a standard integrated 10Hz
GPS/QZSS receiver, with an accuracy of 2.5m
in position and 0.1m/s in speed. K5 accurately measures both altitude and grade by
using the internal barometric pressure sensor
coupled with GPS readings.
Integrated GPS
2.5m position and 0.1m speed accuracy
GPS data can be monitored real time on K5 display
and, eventually, downloaded (together with K5 metabolic parameters) in mapping software like Google
Earth or Cesium
Wireless Connectivity
Great attention has been given to allow K5
more efficient wireless data transmission
and seamless integration with other devices.
Provided with both standard and optional
wireless data transmission K5 is also compatible with Bluetooth 4.0 technology enabling
integration with external peripherals such as
ECG, SpO2 monitors etc.
