描述

The 17305400 is a solid-state hour meter or counter from the Curtis 700 Series, featuring a 6-digit LCD display (5 or 7 mm high) with 6 o'clock viewing angle and nonvolatile EEPROM memory that retains data for 25+ years without power. It offers a range of 99,999.9 hours for hour meters or 999,999 counts for counters, with accuracy of 0.1% for hour meters and ±1 count for counters, operating across AC/DC voltage ranges from 48 to 440 Hz. The unit operates reliably from -40°C to +85°C, withstands mechanical shock of 55 g and vibration of 20 g per SAE J 1378, and consumes minimal power (0.5–2.0 mA depending on voltage). Ideal for scheduled maintenance tracking, warranty management, and leasing applications in medical equipment, transport vehicles, and industrial machinery, the device combines silent operation, electrical reset capability, and multiple case styles to fit standard hour meter cutouts.
