Digital 4 Channel Thermocouple Thermometer Temperature Recorder Data Logger AZ Instruments Multi Channel K Type Thermometer Thermocouple Reader with 8G SD Card 2 Bead Type K-Thermocouple Probe

Easy to use, captures data and is very easy to load to Excel for analysis.

Great piece of equipment, good features, works exactly as the ad says, runs on batteries or optional mains adaptor which isn't included.

I bought this 4 channel Temperature Data logger to analyse a Samsung Heat Pump. The Logger records the temperatures of four K type thermocouples , putting the results into an Data file on an SD Card. The logger comes with only two bare wire K type Thermocouples. On tying to attach the bare wire K type thermocouples on to copper piping proved to be very difficult, if not impossible , so, I purchased Four K Type pipe Clamps. With the K type pipe clamps I could, finally, explore the other functions on the logger. The logger is very dated in it's presentation with commands displayed in a dated, very difficult to read character set. The Logger , once "set up " is very simple , and accurate in use. The Results are dumped to an SD card in very large , but easily read list format. So, an Accurate , simple device that should be supplied with Clamp K Type sensors . The character set used should be replaced ASAP. However, an Simple device at a very reasonable price.! Six months on , the Device is still working flawlessly taking Dailly readings of a suspect Heat Pump!

On off button has become very not working, mostly! Membrane switches not good. Shame as otherwise fantastic!

Can't work out how to connect the device to the software. Any advice please? Delivery and timing brilliant

I've been using for logging flow and return temps. on my central heating system over the winter period. One word sums it up, brilliant. Has worked faultlessly. Am amazed at the battery life. The only mod. was to buy and SD cards extension lead from ebay so I could leave the logger in situ and easily remove the SD card for loading the data on my PC

I found this to be accurate and the data can be manipulated in Excel to make graphs etc. I left it in place for 2 weeks and the battery was still showing full. The cost is a lot less than similar products sold by specialists.

I bought this product as I needed to monitor several thermocouples at once without the use of a laptop - This product does what I need. The data is stored onto a removable SDHC Card which is then easily uploadable to a computer. The only reason I give this 4/5 stars and not higher is because the manual is lacking information, IE how to set the date and time (American format Btw) and how to change the time gap between measurements. This doesn't take too long to work out with a little patience. The data is saved in a single line to a text file, if you want to open it in excel you have to load it as a space delimited set of data (meaning where there is a space excel will make a new column) - it's not a hassle. There are two holes on the back of the logger which you can use to hang it like a picture, I have got some M3 bolts attached to magnets which I use to magnetise the logger to the steel wall. Overall a good product which I look forward to using
