The Scace 2 is the next level of Scace temperature measurement tools and is exclusive to EspressoParts.com.

The Scace 2 Thermofilter gives you both temperature and pressure readings directly at the group. This is where we are most interested in receiving data, and now you can do both. The device is very capable of measuring temperature to within a 10th of a degree. The "T" type thermocouple is very fast and accurate when used in conjunction with a Fluke digital thermometer.

While we are fans of the Fluke brand, there are other brands and models of digital thermometers, all you need to make sure of is that the device can read "T" type thermocouples.
Pressure is the other fluctuating factor when we discuss stability in an espresso machine. Knowing your brew pressure is just as important as the temperature, and we have found that coffee can taste quite different at variable pressures.

The Scace 2 Thermofilter has an integrated glycerin filled pressure gauge that provides accurate brew pressure.
