How Reliable is the Temperature Control in a Hem Brew System?
The automated thermal regulation unit relies on a 24V DC PID module paired with PT100 sensors, checking mash temperatures at a 10Hz polling rate. A 2023 independent hardware analysis (n=150 trial runs) showed the equipment maintains target saccharification temperatures within a ±0.4°C margin over 60 minutes. Standard single-vessel setups often show a 2.1°C variance during […]
