• Microprofiling, manual or automated, of biological matrices

• In situ equipment for field, underwater, deep sea, and shallow water research

• Eddy Correlation system for measuring oxygen fluxes

• Microrespiration and metabolism

Unisense Unisense provides high performance microsensors and complete measuring systems for a full range

of applications in environmental and medical research.

We are dedicated to provide researchers with excellent support and complete solutions

in the laboratory as well as in the field

SensorsMicrosensors are a unique research tool for non-destructive

and real time measurement of analytes

on a micro scale. Further advantages include high

spatial resolution and low detection limits.

Unisense provides several options for customization

of e.g. tip size, response time, stirring sensitivity,

and other custom adaptations to ensure accurate

measurements for your application.

Microsensor Multimeter

Versatile 4-channel microsensor amplifier

for all Unisense sensors.

• Ease of use and simple data acquisition

• 2 amperometric channels for analyte measurements,

1 channel for pH or Redox and 1 channel for temperature

• Automatic sensor detection

• Operated via OLED display and keypad

• USB connectivity to Windows® PC

• Battery, external voltage, or mains power operation

• SensorTrace Basic Windows® software included

Microsensor X-Meter

This custom version of the Microsensor Multimeter comes

pre-configured for your choice of four analytes (e.g. N2O, NO,

H2S, H2, NOx-, Flow, Diffusivity). Other benefits are as listed

under the Microsensor Multimeter.

Microsensor Monometer

Single channel version of the Microsensor X-Meter. The meter

comes pre-configured for your choice of analyte. In addition

to the pre-configured channel, the Microsensor Monometer

comes with one temperature channel.

OXY-Meter and pH/mV-Meter

Small and easy-to-use one-channel amplifiers

for oxygen and pH or redox, respectively. Powered by USB

and with a built-in A/D-converter, data are simply transferred

to your PC for further analysis by our SensorTrace

Windows® software.

UnderWater Meter

Unisense UnderWater Meter is a multimeter designed for

field measurements under tough conditions, giving you

a unique opportunity to perform in situ measurements.

• Robust and waterproof to 30 m

• Easy operation with

magnetic contacts

• 4 channels to be used with

any of the Unisense sensors

• Digital outputs for

data extraction

SensorTrace PRO

SensorTrace PRO is our software for sensor positioning and

data acquisition for manual or automated microprofiling.

• Collects data from up to 16 microsensors at a time

• High-resolution spatial profiling

• Isopleth visualization over time and space

• Direct visualization of activity in the system. Dynamic

online modeling of the distribution of production or

consumption based on the measured profiles

• Control of up to three motorized micromanipulators,

enabling complete automation of multiple profiles

in 2D and 3D

MicromanipulationStability, precision, and excellent spatial resolution

With our micromanipulation system you gain complete control

of the positioning of your microsensors, enabling you to study

precision microprofiles in a variety of biological matrices.

• Stable positioning of microsensors

• Accurate positioning down to 0.5 µm

• Manual and automatic positioning in up to

three dimensions

Amplifiers and SoftwareUnisense provides a full set of solutions for data acquisition and handling.

Whether you want to measure one or more analytes, or whether you work in the lab,

the field, or even under water, Unisense has the meter that fits your needs

UnderWater Meter

Designed for underwater studies. Combined with our

in situ micromanipulator system, it gives you a unique tool

to investigate shallow water habitats, including coral

reefs, sea grass patches, or lake and river sediments.

Eddy Correlation measurement of oxygen fluxes

Unisense now offers you a complete solution to study

the important parameter of oxygen flux between the

sediment and overlying water based on the eddy

correlation principle. Our system includes all

components for complete data acquisition with

a rapid responding oxygen sensor, a high resolution

amplifier, and a 3D velocimeter.

MiniProfiler MP4

The MiniProfiler MP4 System is an excellent tool for long-term

studies with continuous and automated measurements in

the field and shallow water. It allows 1D or 2D profiling

of four analytes in up to 50 meters depth, and can stay

deployed for up to one month.

MicroProfiling SystemDiscover the detail

Study microprofiles in sediments or biofilms, determine

small-scale gradients, follow temporal changes, or measure

photosynthetic production with the light-dark switch

technique. Our applications vary from sea floor

biogeochemistry and plant physiology to various fields

of human physiology including kidney, cancer,

and brain research.

Unisense micromanipulators,

amplifiers, and microsensors enable

you to study the details

of your sample!

MicroRespiration SystemO2 metabolism in closed micro systems

Study O2 and even pH, H2,

H2S, N2O and NO metabolism

with the MicroRespiration

System.

This complete system

includes chambers that

prevent oxygen diffusion,

rack, magnetic stirring,

sensor, amplifier, and

software. When measuring

oxygen, our MicOx software

facilitates real-time, online

inspection of data, and creates graphs of respiration rates

from multiple samples.
