The short answer is: Both models share the exact same internal cooling systems, dimensions, and features. The different suffix (25 vs 26) typically denotes the region or retailer for which the unit was packaged.

If you are calibrating equipment to ISO 17025 standards, the HD3720 26’s enhanced accuracy is non-negotiable. hd3720 26 vs hd3720 25
The defining characteristic of the HD3720.25 (and the older generation of Udor pumps) is the use of a . The short answer is: Both models share the
If you are choosing between the two, simply pick the one that is currently or specifically listed for your region to ensure the correct power plug is included. PerfectDraft Home beer draft system HD3720/26 - Philips The defining characteristic of the HD3720
offers a 0-10 V voltage output (or optional RS-485). While 0-10 V is common in building automation and laboratory equipment, it is susceptible to voltage drop over long distances (>30 meters). The three-wire configuration requires a separate power supply and ground, increasing installation complexity but allowing for bidirectional digital communication if Modbus is enabled.
The HD3720 26 (3-wire) is prone to ground loops if the sensor ground and PLC ground are at different potentials. Use an isolated power supply. The HD3720 25 (2-wire) is inherently less susceptible.
