Review: Time Resolution is 5 Seconds (Not 1 Second) / Update: Firmware Solution is Available - This temperature logger is a nice unit. I like the looks, interface, and functionality. Unfortunately, this unit is only good for slow temperature fluctuations as it will not refresh the temperature faster than 5 seconds. It does record data at 1 second intervals (as advertised), but the actual resolution is 5 seconds. This is apparent when you are measuring temperatures that are quickly changing, the log records the same temperature for 5 consecutive seconds, and then the temperature jumps (in my case 4-5 degrees C) and stays flat again for another 5 data points. I reached out the to manufacturer and they tell me that the unit is operating normally. I'm having to massage the data in a spreadsheet to create an average/smoothed curve, but it's not ideal. UPDATE: I was contacted by the manufacturer. They worked with me to better understand the issue. I have since been given a firmware update (version 1.15) which enables the unit to refresh & log data as low as 1 second intervals. I am now very happy with the device since the update! Thank you!
Review: Versatile Dual-Channel Logging with Solid Accuracy - We tested the Tzone TC602 dual-channel data logger for some HVAC and lab-style temperature tracking, and it is a very capable system for the price. The interface is clean, and the ability to track two probes simultaneously—complete with a T1-T2 calculation function—is almost mandatory for many industrial or engineering scenarios. In terms of accuracy, we spot-checked the unit against another calibrated K-type thermometer, and the results were very consistent. The build quality is decent; it feels solid enough for workshop use, though it doesn't quite reach "heavy-duty industrial" status. The user interface is mostly intuitive, but we did have to consult the manual a few times to navigate some of the deeper settings. A few things to note from our testing: Graphing & Auto-Off: The system features a nice graphing mode on the LCD. However, we found that if the unit auto-shuts down to save battery, the graphing stops. This is likely adjustable in the "auto-off" settings, but it's something to watch out for if you need a continuous visual log. Probe Limits: The included K-type probes are rated for up to 300°C. While the device itself can handle much higher temperatures (up to 1372°C), the insulation on the stock probes isn't designed for extreme heat. For high-temp oven work, you’ll want to swap them for fiberglass-insulated probes, which we confirmed work perfectly with this unit. Data Logging: A significant feature of this unit is that it can generate PDF, CSV, and XLS reports automatically when plugged into a PC via USB without needing proprietary software. While we did not test this specific functionality extensively—as it isn't a primary part of our usual workflow—it is certainly a nice feature to have for those who need to document long-term data. Overall, this is a well-featured system that provides professional-level logging at a hobbyist-friendly price point. We give it 4 stars.
