Stop Modes: Memory full, never stop (overwrite oldest data), date & time, or after a set logging period
Water Detect: Events are logged when logger is submerged or removed from the water (MX801 only)
Time Accuracy: ±1 minute per month 0° to 50°C (32° to 122°F)
Battery: Four AA, 1.5 V lithium batteries, user replaceable
Battery Life:
-
With W-CTD or W-CT sensors: 2 years, typical with 1-minute logging interval or slowerWith W-DO sensor: 1-year, typical with 5-minute logging interval or slowerFaster logging or statistics sampling intervals, entering burst logging mode, excessive readouts, and remaining connected with the app will impact battery life
