Thermocouple Thermometer Data Logger 4 Channels Digital K Type Thermometer with 5000 Groups Programmable Temperature Recording -328~2501℉ Measuring Range, Audible & Visible Alarm ADJ Compensation

Why did you pick this product vs others?:Get this and a k type probe for grilling. Works great

Works well, except that min/max/ avg does absolutely nothing, continues displaying both current temperatures in those modes.

The seller is dedicated to customer service. Initially I gave this a one star review because the unit was defective out of the box. One of the LCD segments was non-functional. I returned the initial unit.The seller reached out to me and offered me a replacement unit free of charge. I accepted the unit and it works great. It appears to be within a degree of calibration. I checked it using an ice bath and boiling water.Over all I'm very happy with the unit.

Works like a charm

Unit was cheaply constructed I put batteries in it turned it on and compared the two temperature TC's they were off by 2 degrees then I tried to turn it off and the only way to eventually remove the batteries.Amazon has had several items that I purchased over the past couple of years that I had to return because of poor quality as they were all made in China. Amazon needs to purchase more products made in the USA

Device: decent build. Great display. Viewing data points on device handy. Can read data while recording. Date and time cannot be set in device, you will need to make a note of when you start recording.Software: looks and feels like its from 1995. Defaults to celsius; change units in right hand side prior to importing data. Live data recording is handy. Exporting table to excel nice BUT it includes the degrees symbol, which makes using the data hard. HINT: use =substitute function to remove degrees and then use =value function to turn it into a number. Youll essentially have to build a template to copy and paste exported data to in order to use it. It is dumb you have to do this to use the data and i have removed a star just because of this.Getting this device to communicate with COM ports is tricky. Youll need to enable COM ports in the device manager under legacy software. Once thats done youll notice when you plug it in a port appears with a "!" on it. This means it doesnt have the correct driver. Google search "CH341SER" and the first link will bring you to a downloadable file. Download file. Then go into device manager and manually update driver for this port while device is plugged in. Search that downloaded folder and computer should pull drivers it needs. Should work after that.Function: instructions are missing info. Doesnt talk about calibrating and using adjustment feature. My understanding is you can adjust each channel by whole number degrees to calibrate it. Boiling water would do the trick. Note that calibration technically depends on length of wire. Wish the time intervals were better; it goes from 1 minute to 30 minutes with no way to change it (10 would be nice). This gets annoying cause it only can store 5000 points... so at 1minute thats almost 3.5 days.

I bought this to measure the temperatures along my attic a/c return duct to find a leak that no one could find. When the temperature went from near room temperature to up 10 degrees it let me know where it was. I also used both input sensor ports to compare the differences. Well worth the money since it gave me the knowledge on how I needed to solve the problem that I have.

This TC data logger is a great value, just what I needed. It’s robust and provides a way to graph and record Temperature data accurately from 4 thermocouples to a computer continuously to monitor and save for analysis at a price point that’s a fraction of most other options. The supplied usb cable had an issue with the computer plug end not connecting securely so had to replace.
