Chris' Price: $109.50

Product Code: SSS-04


The purpose of this adapter and digital thermometer is to facilitate the measurement of brew water temperature about 1.25" away from the puck during a real brew cycle. In addition, and equally important, it measures the temperature of the group-head under idle conditions. It requires no drilling, tapping, soldering, brazing, cutting, Teflon tape, or epoxy but can ONLY be installed in E61 group-heads that are fully exposed. The difference between the temperature that you will be measuring using this adapter and measured temperature of the water hitting the puck is approximately 3-5 °F but may vary with different machines and different brew conditions and most certainly, varies over the course of a typical 23-27 second shot. The new style thermometer has switches for both the on/off function and temperature scales (°F/°C).

Works great until it opens / needs to be opened October 24, 2017
Reviewer: Anonymous Person from Cupertino, CA United States  
The thermometer works fine until it either opens because you accidentally "touched it the wrong way" or it needs to be opened to replace the battery. I guess the material is just not strong enough to withstand the frequent - for this device - extreme temperature fluctuations.
There are a few complaints / suggestions for improvement:
1) Once the thermometer is opened, it will not close as tight as it originally was.
2) The solder joints and / or the wires are very flimsy.
Wire and solder joint performance started to deteriorate, which at first led to higher temperature measurements that normal, before those cables broke off [the solder joints].
I may try this device one more time because it is a helpful control parameter. But if the thermometer falls apart again, "that's it" ...

I must say this product is phenomenal. It helps my Dad making his milk based lattes and he loves it. No flaw what so ever. Thanks to Chris Coffee for having this product.

Works brilliantly! April 14, 2017
Reviewer: William Mckenna from Dalkeith, Midlothian United Kingdom  
I thought about this for a while, after using a thermocouple hooked into the top of the coffee in grouphead. Initially out of stock, but within a few weeks I received an email from Chris Coffee saying now available.
Ordered on the weekend but by Wednesday it had reached Bonnie Scotland......fantastic service!
Only issues were $109+$46 shipping +$43 import tax which makes it pretty expensive in the U.K.
Having said that, no regrets as it does exactly as I'd  hoped it would. Takes 2 minutes to fit! Thanks to Eric  for manufacturing and Chris Coffee for making it happen.
