PEM sample holder
The polymer electrolyte membrane (PEM) sample holder for ProboStat™ is a PEEK head to be mounted in the top of a standard ProboStat™ support tube. It has a flat top surface with 4 wire electrodes onto which the polymer film is pressed down with the spring load of the ProboStat™, for measuring the in-plane conductivity primarily of polymer electrolyte membrane films, but also other flexible and/or soft films. It can operate at temperatures and conditions where the PEEK and metal parts are stable, typically long term up to around 200°C, for shorter term e.g. 250°C. The PEEK head is replaceable.
4-Leg thermoelectric test module
Our new 4-leg thermoelectric test module is specially designed for our ProboStat. With an efficient water-cooling system enabling large temperature gradient between the hot side and the cold side, together with the full function of the ProboStat, it is perfect for thermoelectric tests on stability and performance, Seebeck coefficient, module power factor, etc.
Large sample setup
A new setup has been developed on customers request. It is specialized for measurements on disk samples with diameters 25 to 60 mm. The Large sample setup is compatible with the standard ProboStat™ base unit. It is applicable for measurements of electrical properties in the ProboStat single atmosphere mode.
HumiStat - new laboratory gas mixer with large dynamic mixing rate and humidification
NORECS now offers a small-footprint gas mixer suitable for low-flow laboratory use such as materials- and button fuel cell research, where large dynamic dilution range, accuracy, and automated step-programs are important. The accompanying software is simple, and guides the user step-by-step through the definition of mixtures and describes the mixture in all typical units.
- Dynamic mixing of two input gases and one input fluid (all upon request)
- Fully continuous, truly dynamic range, allowing accurate gas dilutions all the way from 2·10-5 (20 ppm) to 100%.
- Continuous range of water vapour levels from bottle dry gas to pure steam.
- The mixer is not limited only to H2O as the evaporating fluid.
- The operating cycle is perpetual; gas mixture production can run while more water (or other fluid) is being added.
- Flow of the gases are typically < 100 mln/min, but can be adjusted per request.
- Competitive pricing.
Platinum ink, supplied by NORECS, is an excellent conductor of current containing no less than 70% Platinum by weight. This is a great ink for making electrical connections for testing of fuel cells, ceramic substrates, electrochemical materials, and metals.

Advanced ceramic oxide materials
NORECS supplies a wide range of customized ceramic oxide powders for advanced energy applications:
- electrolyte, cathode, and anode materials for solid oxide fuel cells,
- materials for gas separation membranes,
- lead-free electroceramics, etc.
Supports with integrated electrodes for films and 2D materials
NORECS now offers two new ranges of supports with integrated electrodes for measurements on films.
Interdigitated Electrode Arrays (IDAs) for deposited thin films and 2D materials
Here we will supply a fixture for standard IDAs from various suppliers, as well as custom IDAs. Measurements in a ProboStat allow elevated temperatures and controlled atmospheres.
4-electrode supports for self-standing polymer films
For conductivity measurements of polymer film slabs (e.g. PEM) we now develop a support with 4 electrodes in the shape of 4 integrated wires. The support can be mounted in existing or new ProboStats at any height of 20 mm support tubes. Expected temperature range from RT to 200-300°C, so heating can suitably be done with a heating mantle. Heated base units allows high steam contents if desired. Electrode wires of Au (default) or e.g. Pt or Ag. Contacts to the support from the ProboStat base can be done using standard ProboStat style Pt electrode contacts or simply Cu wire.
