HOBO by OnsetHOBO by Onset UX120-006M Analog Data Logger

I have three of these loggers and like them very much.I'm a retired engineer who was involved in testing and logging, so I'm pretty picky.The Onset loggers are professional quality, quite accurate, support a wide variety of sensors, reasonably priced and have always been durable and reliable for me.Before this new version of the 4 channel logger came out, I had a half dozen of the older 4 channel loggers and they were also quite good. Our dog knocked down one of them that I had in a protected spot outside -- it ended up in a puddle of water. I dried it out with a hair dryer, and it worked fine!Only nit I have is that the price of the temperature sensors are high for just being a simple thermistor sensor.

The logger did not meet specs. Different channels show different temperatures in ice bath. Contacted tech support three weeks ago in this regard. They did not help to resolve this despite calling 3 times. Now the 30 day period has passed while i was waiting for them to help resolve the problem. Pour accuracy coupled with pour technical service.

This unit has been working great for my purpose (measuring shade on hiking trails). I attached a light meter (from another company) to one of the data ports, using a cable recommended by this company, and I have collected tens of thousands of data points with almost zero effort. Their free software works seamlessly on my laptop, and I’ve had no problems with data acquisition setup or retrieval. The unit weighs almost nothing, which is great. Very satisfied with performance.

This data logger does not come with any probes or adapter to connect to a computer.

Recording measurements is specially easy wit this datalogger

This is a great data logger. Good capacity and statistical capabilities. Ability to view channels is also very helpful. Have bought a couple of these and will buy more. My only complaint is that the cables needed are expensive at around $12 ea. That adds significant cost.

Easy to use

Works great ! Instructions a little confusing.
