Level accuracy is ± 0.05% FS and temperature accuracy is ± 0.05°C.\u003c\/p\u003e\n\u003cp\u003eSeries 6 brings enhanced electronics with better stability and sensitivity across the temperature range, a 100,000-reading memory backed by a dedicated 15,000-reading store, stored time stamps for local, GMT or UTC display, and download speeds doubled to 19.2k baud with the Mk3 USB-C PC Interface Cable. Sampling runs from 2 seconds to 99 hours in linear, event, and user-selectable schedules with repeat and pause. Read out with a Solinst Readout Unit, DataGrabber, PC Interface Cable, or over Bluetooth® with the Levelogger App Interface; the LTC is SDI-12 and MODBUS compatible via an Interface Cable and integrates with LevelSender cellular and SolSat satellite telemetry.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFor long deployments\u003c\/strong\u003e, consider a Biofoul Screen — a Delrin sleeve wrapped in copper wire that slips over the sensor end by compression fit and uses the natural anti-fouling properties of copper to slow the buildup of algae, barnacles and mussels on the pressure sensor and conductivity cell.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChoosing a range.\u003c\/strong\u003e All models carry the C80 conductivity range; the M number is the maximum submergence depth in metres.\u003c\/p\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eFull Scale\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eAccuracy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eResolution\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM5, C80\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5 m (16.4 ft)\u003c\/td\u003e\n\u003ctd\u003e± 0.3 cm (0.010 ft)\u003c\/td\u003e\n\u003ctd\u003e0.001% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM10, C80\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e10 m (32.8 ft)\u003c\/td\u003e\n\u003ctd\u003e± 0.5 cm (0.016 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM20, C80\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e20 m (65.6 ft)\u003c\/td\u003e\n\u003ctd\u003e± 1 cm (0.032 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM30, C80\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e30 m (98.4 ft)\u003c\/td\u003e\n\u003ctd\u003e± 1.5 cm (0.049 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM100, C80\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100 m (328.1 ft)\u003c\/td\u003e\n\u003ctd\u003e± 5 cm (0.164 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eM200, C80\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e200 m (656.2 ft)\u003c\/td\u003e\n\u003ctd\u003e± 10 cm (0.328 ft)\u003c\/td\u003e\n\u003ctd\u003e0.0006% FS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cstrong\u003eDo you have everything you need?\u003c\/strong\u003e The Levelogger 6 LTC measures absolute pressure, so it needs a \u003ca href=\"https:\/\/envirotechonline.com\/products\/solinst-barologger-6\" title=\"Solinst Barologger 6\"\u003eBarologger 6\u003c\/a\u003e for barometric correction.
