IMES EPM-XP

The IMES EPM-XP is a battery-powered handheld electronic indicator for regular pressure monitoring, diagnosis, and balancing of 2-stroke and 4-stroke diesel engines. It uses the HTT-06 cylinder pressure sensor, built for stable long-term thermodynamic accuracy without frequent factory recalibration. Onboard features include automatic top dead centre correction, a sensor accuracy check, P/alpha diagram visualization with automatic Pcomp calculation, and Pmax/Pcomp balancing screens, shown on a large display with two navigation keys. Recorded data transfers over USB 2.0 to IMES's own visualization software (Windows 7/10/11). A firmware upgrade to EPM-XPplus adds indicated power and IMEP calculations, p/vol loop diagnostics, and trend tracking.
