Measurement Fair Sensor + Test 25.06.- 27.06.2019

itg exhibitor at the Sensor + Test 2019 – hall 1, booth 1-528

Starting from this year itg offers a line of downsized lead free, fast response oxygen sensors called the 400-series dedicated to handheld instruments in medical and industrial applications such as breath analysis as well as smoke gas measurements, personal safety and environmental monitoring. The whole range is RoHS compliant and resistent to most acid gases like CO2. MORE

itg receives some co- funding to file it’s
Patent DE 2013 011 773.8
for a lead free medical oxygen sensor internationally.

Now NO vs NO2 discrimination is available

itg is proud to announce a line-up of trace gas sensors for various gases:

Nitrogen oxides - as commonly defined by emission regulations and regulatory measurement protocols - include two major gases: nitric oxide NO and nitrogen dioxide NO2. In most applications it is important to monitor both constituents’ concentrations from ppb up to low ppm ranges independent of each other at the same time. Furthermore, in the medical fields repeatable and drift-free results in nitric oxide measurements used for FeNO breath analysis detection and in pulmonary hypertension treatments are important features. itg's amperometric NO and NO2 cells such as I-27A/I-27D/I-28D/I-29D and I-55D meet these requirements at low interference rates.

Carbon monoxide - is a toxic odorless gas mostly produced as a by-product of an incomplete combustion. U.S. standards define a maximum of 9 ppm of CO for 8-hour exposure over a year as acceptable with no health effect. Beside being used in managing indoor air quality, leakage tests and monitoring of furnace emission, in the medical field the sensor can aid in smoking cessation or in screening for CO poisoning. This sensor can detect low ppb-levels of CO at very low gas flow-rates.

Digital sensors available from December 2017

itg now launches a new line of electrochemical O2-sensors equipped with an 16-bit Analog-to-Digital Converter (ADC). All sensors come with an on-board temperature correction unit to compensate the output signal.

Based on the I2C-bus communication protocol these sensors deliver a noise-free digital output signal directly proportional to the oxygen level measured. Moreover, the I2C-bus communication is relatively immune to electro-magnetic (EM) interferences allowing to place the processing unit away from the sensor.

Classic galvanic fuel O2-cells, when hooked-up to different impedance loads tend to underperform in linearity and in some cases also in response times. Thanks to the digital interface these drawbacks are history.

Currently itg offers its entire line-up of lead-free and RoHS compliant O2-cells and some trace gas sensors (I-27D, I-28D, I-55D) as digital version on customer request.

Sensors will be available starting from December 2017. For any questions or enquiries please contact us at

Introduction of a new line of fast and lead free sensors

itg now offers a new line of fast and lead free galvanic oxygen sensors that of course comply with RoHS.

MLF-350 comes with a response time of less than 350 ms and MLF-650 with less than 650 ms. Sensor MLF-350 has a measurement range up to 35 Vol.% of O2 and MLF-650 can measure up to 100 Vol.% O2. High quality, robust construction and long expected operating life of the sensors allow to optimize costs with no compromise on performance.

The sensors withstand CO2 and can thus be used for breath analysis and also various industrial applications like e.g. food packaging.
Products: MLF-350, MLF-650

Measurement Fair Sensor + Test 30.05.- 01.06.2017

itg exhibitor at the Sensor + Test

This year itg brings to market a line of first of its kind electrochemical gas sensors for aldehyde compounds. Aldehydes, especially formaldehyde are carcinogenic and difficult to measure with existing technologies. The development of this new range is a breakthrough in the sensor world.

itg will also present NO/ NO2 sensors which excel at low cross-interference to each other and to all other exhaust gas constituents. Such sensors can also be used in the treatment of hypoxic respiratory failures.

The third group of the sensors presented at the fair are H2S sensors which are entirely H2 resistant. They can work from ppb range up to 10.000 ppm and also in continuous mode. Even with ten times overload they will work perfectly and recover fast ensuring highly reliable measurements.

If you want to know more, please contact us directly or visit us at our booth 1-517, hall 1.

Compliance to future RoHS Directives

itg information about RoHS - lead free offer

In July 2011 RoHS II,
the Recast RoHS Directive (Restriction of Hazardous Substances),
was published and has meanwhile been adopted by most European member states as it came into force by January 3, 2013 already.

For the time being gas sensors, oxygen sensors in particular, are exempted from this recast Directive as to find in article 4, Annex IV. For Industrial Monitoring and Control Instruments this exempting time-period will come to an end with July, 22, 2017; for medical devices the exemption ends even earlier, on July 22, 2014.

After these dates, manufacturers of electrical/electronic products, devices or equipment must include compliance with the RoHS Directive in their Declaration of Conformity before placing CE mark.

We have launched a new technology for itg oxygen sensors, which does not make use of heavy metals that are relevant to RoHS such as lead as electrode material.

itg produces "lead-free“ cells for quite a while now, thus can look back on some years of intensive field tests - not only in the medical field but also in some industrial areas. MORE

itg on TV

itg contributed a sequence

to the tv-format “Wirtschaftsfenster” broadcasted on German regional tv “Wismar TV und Meer” from July the 12th until July 16th 2013. For your service you also find the sequence in the archives of the format or under

itg keeps on growing…

Since several years itg keeps on growing.

The accomodations obtained in 2010 have already become insufficient to comply with the claims of our customers and adequately promote the development of new gas sensors.

itg thus widens R&D facilities and production site about 500 sqm and reconstructs a new, adjacent, building, that will offer further space for administrative offices and manufacturing plant.

You will still find us in Wismar. Same street.
The works will be finished by the beginning of July 2014.

Improved ppm-O2 sensor

itg is proud to present an improved ppm-O2 sensor that now can stand high amounts of hydrogen as cross-gas.
Since electrochemical sensors usually lacking on signal stability when exposed to more than 10 Vol.% of hydrogen, this revised P-41A is able to perform perfectly with no loss on operating life. MORE
Product: P-41A

Biogas – H2S-Monitoring

Anaerobic digestion processes play a very significant role in the field of sustainable energy production from biomass. Oxygen and Hydrogen sulfur provide amongst other parameters an economical real-time determination of the optimal substrate combination and process parameters, which in turn lead the maximal efficiency of biomass reduction and yield of biogas.
