Serial (COM) communication protocol (option)
This product is available with the option of communication via virtual COM port protocol. Products with this option can be freely converted between USB and VCP communication modes. For more information about this option, consult the documentation of the VCP option.
Of note, for Windows 7 users, here is the installation procedure.
Here is what the invocation of the command INFO returns for this product:

3-point user calibration mechanism (option)
This product can be equiped with a 3-point user calibration mechanism. Devices equiped with this feature are eligible for future recalibration, and can be recalibrated either by the user or by a calibration laboratory. Use this option to “synchronize” several of your measuring instruments with each other, or if you want the ISO/IEC 17025-accredited laboratory we work with to calibrate your instrument and generate a NIST-traceable certificate. You can find more information about NIST traceable certificates here.

Do you have STEP/CAD files of your instruments?
You can find them on each instrument page under the Datasheets tab if available.
Are your sensors battery-powered?
No, they are not. They are powered via the USB plug; therefore, they must be plugged in to transmit data.
Why are my readings 0.00 when I plug the VOC100?
The VOC100 needs about 30 minutes to perform a baseline calculation of the compounds to produce reliable results.
How sensitive is the VOC100?
It is very sensitive to many compounds and sudden variations in temperature and humidity. The output is additive when many compounds are detected. These can include temperature and humidity variations.
Slower changes than the adaptation rate of the instrument should minimize the impact of temperature and humidity variation.
What do you mean by “semi-quantitative” readings?
The technology of the volatile-organic compound sensor used in the VOC100 allows the detection of several components simultaneously and works with a precision of about 15%.

What are the advantages of choosing a calibratable instrument (-CAL option)?
The devices with the 3-point calibration mechanism have a longer lifetime as it is possible to compensate for the natural drift of the measurements. The cost/lifetime ratio is thus considerably reduced and, just as importantly, this choice is environmental friendly.
These devices can be easily calibrated and certified by external resources (including our ISO17025 certified partner laboratory) and allow you to synchronize your various devices between them.
What are the advantages of using your USB communicating devices over other technologies?
| 1. Connection security. | 6. Continuous power supply. |
| 2. Instant access to data. | 7. Low-power supply. |
| 3. Data confidentiality. | 8. Self-sufficiency. |
| 4. Data reliability. | 9. Technology persistence over time. |
| 5. Fast response time. | 10. Universal access. |
Can I use your measurement devices while maintaining my current software infrastructure?
Yes, you own your data. To integrate your data, you can either use our CLI (command line interface) for which we have plenty of code examples or for more advanced users, by choosing the VCP (Virtual COM Port) option when selecting your product.
How many devices can be simultaneously managed by your software tools?
Unlimited number of similar and different devices, provided your system supports the load.
What is your warranty policy?
Dracal Technologies guarantees the incomparable speed of use and the exceptional quality of its products, that they are made of new materials, assembled and tested in our factory in Canada, in processes that respect human rights and the environment. We guarantee the absolute absence of any form of programmed obsolescence, and that conversely, we deploy sustained efforts on both our electrical and mechanical designs to extend the life of our devices as long as possible so that the results of the efforts invested by our customers last over time but also, and just as importantly, to preserve our planet. We guarantee unlimited access to all updates of our free software tools. We offer a 2-year material warranty.
