Description
TMP125: Rugged USB Temperature Sensor for Extreme Environments
The TMP125 is a USB ambient temperature sensor designed to operate in extreme conditions, ranging from -55°C to 75°C. Featuring an accuracy of ±1.0°C (-10 to 75°C) and ±2.0°C (-55 to 75°C), it provides a resolution of 0.5°C. Powered by USB with an operating current of 12 mA, this sensor is equipped with a probe resistant to dust, moisture, and water splashes. Its ABS plastic housing can operate in temperatures ranging from 0 to 75°C. With its reliable performance in challenging environments, the TMP125 is ideal for applications requiring digital temperature monitoring.
Like all Dracal measurement instruments, the TMP125 is compatible with free software tools, making it an essential component of a DAQ solution. For those who wish to integrate the TMP125 into their system, there are two options available: command line tools and VCP mode. If you prefer a graphical interface, DracalView is the appropriate choice.

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.
Can I put the TMP125 in water?
No, as the probe has an Ingress Protection (IP) rating of 65, meaning that the enclosure is completely protected against dust ingress and is also protected against water jets projected from a nozzle. It is not wholly waterproof (minimal IP rating of 67).
How do I request a quote?
We have created the easiest possible quote request system for you.
1. Create an account and log in.
2. Then do whatever you would do while shopping, then click on the shopping cart in the top right.

You will then receive a quote by email, which you can accept and pay within 30 days.
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.
