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 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.

Digital Thermometer works great March 12, 2017
Reviewer: Anonymous Person from Apple Valley, MN United States  
We purchased a digital thermometer to use with our Rocket espresso machine.  Installation was simple (but make sure you hand tighten it well, not good or you get a steam powered projectile) so that it was performing perfectly within minutes.  It's been extremely handy to have to make sure the machine is hot enough to perform optimally.  Without the thermometer, our guesses were far from accurate and the quality of the coffee suffered through user error, not the coffee.
The thermometer arrived promptly within a couple days of ordering.  We don't have any complaints and recommend both the thermometer and Chris' Coffee completely.

Nice control of temp, great support. February 17, 2017
Reviewer: Thomas Weaver from Blaine, MN United States  
This product was recommended by a friend and the installation seemed very straight forward and non-distructive, that is can be installed without modification of existing design.   I ran into a little difficulty with the installation as I could not easily screw the device finger tight.  The contact for support was extremely helpful and situation was quickly remedied.  Under magnification there appeared to be a bur in the threads which was easily cleaned with a wing nut from Home Depot.   Since the install, I have not pulled a single sour shot.  This is an essential modification for any owner of an espresso machine with Exposed E61 Grouphead.
