Our pricing varies depending on which sensor you are purchasing. The following pricing structure is followed. - XM: CHF 299 - XP: CHF 479 - XI: CHF 749 - XO: CHF 729 Each sensor (except our XO) can be purchased as bare wires or with a connector. This connector is an additional 10 CHF.     ###### Why measure heat flux if we already have thermocouples? -  Temperature is purely a measure of how hot something is. - Heat flux tells you where the heat is going and how strongly, which is exactly what is needed to compare cooling concepts and to validate models.   ###### What payment methods do you accept? -  We can offer an invoice or direct payment online through our web shop.   ###### What are the main differences between your gSKIN® heat flux sensors?  gSKIN® (XM, XP and XI) are similar heat flux sensors but differ in size, sensitivity and electrical resistance. - High sensitivity - Thin dimensions (0.5mm) gSKIN®-XO is more commonly utilized within the building industry due to its thicker design, lower sensitivity and lower heat flux measurement range. - Lower sensitivity - Thickness of 3.3 mm   ###### Are the heat flux sensors reusable? -  Yes, our heat flux sensors are designed for multiple uses. We do encourage customers to recalibrate their sensors every 2-3 years.   ###### Are your heat flux sensors compatible with all dataloggers? -  Yes, our sensors are compatible with most dataloggers on the market. - We are happy to double check this information if you send your current data logger model to us.   ###### How do I retrieve the data from my gSKIN® heat flux sensor? -  If you purchased a gSKIN®  DLOG datalogger, your data will be recorded through our greenteg software. Here, the data can be exported or saved for analysis. - If you did not purchase a data logger, you would not have received this software. You can proceed with your existing logger and software.   ## Measurement Method & Accuracy ###### Where can I place the heat flux sensors? - Typically, our heat flux sensors are placed between two materials or on the surface. This is standard for battery applications. - For specific inquiries, we are happy to consult with our R&D team for a more precise answer to your question.     ###### What standards do your heat flux sensors meet? -  Our heat flux sensors are all compliant with ISO 8301 standards.   ###### Do I need to calibrate the heat flux sensor? -  No, our heat flux sensors all arrive already calibrated, and you will receive a calibration certificate with your purchase. - We do recommend that customers re-calibrate their sensors after 2-3 years of usage.       ###### Will the heat flux sensor disturb the measurement? - We use thin sensors and practical mounting methods. We are available to help guide placement, so you get useful data without disrupting your setup.     ## Sensor Mounting & Environment ###### What temperatures can your heat flux sensors withstand? - Our XM, XP and XI heat flux sensors operate within a range of -40 to +85 degrees Celsius for optimal results. - Our XO sensors operates at -15 to +85 degrees Celsius.       ###### Where should I place the heat flux sensor on my surface? -  We recommend sandwiching the sensor between two solid surfaces. - You should place the sensors at the thermal path you want to quantify (e.g., on the cooling interface, casing, or a specific location you suspect is limiting performance).   ###### How do you mount the heat flux sensors? - Select your surface of study, ensuring the area is dry, clean, and flat. We recommend cleaning the surface with Isopropanol. - Apply the sensor with your chosen mounting property. Ensure no air is trapped. - Mount the sensor with the positive side of the sensor facing the the direction of heat flux. - Sandwich the sensor between two contact areas.         ###### What do you mount the gSKIN heat flux sensors with? We have several products available for purchasing for mounting our gSKIN® sensors. These are: - Adhesive tape: for a simple, quick set-up where thermal coupling is important. - Thermally conductive paste: used when pressure is applied to fix the HFS in the measurement setup. - Thermally conductive glue: for applications where additional mechanical stability is required.       ###### How do you remove the gSKIN® heat flux sensors? - Apply Isopropanol or alcohol on the sensor and wait 60 seconds and then try to remove the sensor. - Do not try to tear at the contacts.   ## Special Case Applications ###### Do you have any water‑cooled heat flux sensors available? No, our heat flux sensors are only designed for heat flux measurement purposes only.      ###### How would you mount the heat flux sensor onto metal?  Use [adhesive tape](https://shop.greenteg.com/goms-mount-1235/), [glue](https://shop.greenteg.com/thermal-glue-gskin-25/)or [paste](https://shop.greenteg.com/thermal-paste-gskin-mount-1212/). Ensure that the surface is smooth. These products are available for purchase in our web shop through the links in the previous paragraph.   ###### How would you mount the heat flux sensor onto glass? Use [adhesive tape](https://shop.greenteg.com/goms-mount-1235/), which is available for purchase through our web shop.           ###### How would you mount the heat flux sensor on wood? Use thermally [conductive glue](https://shop.greenteg.com/thermal-glue-gskin-25/) or [paste](https://shop.greenteg.com/thermal-paste-gskin-mount-1212/), which are both available for purchase in our web shop.         ### Have more questions? **Didn't find the answers you were looking for?** Reach out to us through our contact us page with your questions, and a member of our team will get back to you as soon as possible.
