Waterproof shuttle for beginners

These photos illustrate how to use the Waterproof Shuttle and a data logger together. We are showing a U22-001 logger for this demonstration, but the same steps apply to any USB-based optic logger. These steps are necessary for initial deployment of a logger and when communicating with the logger directly.

Using a light intensity data logger as an inexpensive light meter

HOBO light intensity data loggers, such as the UA-002-08, are designed to give you a general comparative idea of how much light there is in an area: sunlight v. shade, lights on/off, etc. If you plan on recording specific lighting information or absolute values, these data loggers will not work for you.

Thermocouple wire material rating

Below are ratings on the material, not to be confused with measurement range. Common TC types used on HOBO data loggers: Type-J and Type-T wire is Teflon insulated and rated up to +400°F (+200°C) continuous, and +482°F (+250°C), for 24 hours Type-K wire is glass-braid insulated and rated up to +900°F (+482°C) continuous, and +1000°F (+537°C) for a short single exposure.

Making beaded probes on a thermocouple wire

A thermocouple is a kind of battery made by joining two dissimilar metals together where a small voltage is generated by the difference between teh metals. The voltage gnerated changes with temperature. To make a thermocouple temperature sensor out of thermocouple extenision wire, strip the insulation back a little and make an electrical connection between the two wires. The more reliable your connection, the more reliable the thermocouple. Welding is the best way to form a reliable thermocouple. A resistance welding machine (spot welder) can be used (with practice), and TIG welding works nicely too.

How often do temperature data loggers need recalibration and/or servicing?

All sensors drift over time and they can be tested in a controlled environment to make sure that they are running within the specifications outlined in the User's Manual. You can use methods such as a simple ice bath or an environmental chamber to verify your device is operating correctly.
