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

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.

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

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!

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

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

Great product, good service, well recommended.

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

I purchased this to take pipe temp readings on a problem refrigeration job. With 3 probes connected I quickly found issue I was having. I let this machine log every 30 seconds for 48 hours and it worked flawlessly. I have no complaints about the machine. The instruction book is hard to read, the print is so small and my eyes can't read the fine print anymore. Had to print off manual from internet to make it legible. Seems typical with manuals now a day. Would recomend if you need a temperature data logger.

il termometro funziona molto bene

Producto de buena calidad, tal cual la descripción 👍🏻

Ich kann den Logger uneingeschränkt empfehlen. Ein Kunde schreibt, die Anzeige geht in Rekorderbetrieb aus. Sie lässt sich aber aktivieren, wenn man die Bedienungsanleitung liesst ;-) Per default ist sie zum Energiesparen aus. Das macht auch Sinn. Die Bedienung ist auch nicht so schwer wie manche schreiben. Ziemlich selbsterklärend

Le produit fonctionne comme attendu. Pour une mesure toutes les 10 s, le produit consomme un set de 4 piles AA en environ une semaine. Donc, pour des mesures longues, comme recommandé par le manuel fourni, c'est mieux d'utiliser un adaptateur 9 V marqué comme optionnel. Sauf que c'est pas indiqué quel type de connecteur et quelle polarité. Je viens d'essayer avec un connecteur 5.5 / 2.1 mm, avec polarité + au centre et ça marche.
