LL-ABS-100

The LL-ABS-100 is a precise water level and temperature logger designed for diverse seawater and surface water applications. Encased in a sealed unit, it integrates water level and temperature sensing capabilities with an internal logger for up to 500,000 data points. The LL-ABS-100 includes an Absolute piezoresistive ceramic pressure sensor suitable for a 100m water depth range. This sensor can provide SDI-12 and Modbus outputs for real-time monitoring, or used as a standalone water level logger. (Deplopy cord recommended).

LL-BARO

£390.00

The LL-BARO Logger is powered by an Internal 3.6V Lithium Battery, or 6-24vDC externally powered and records atmospheric pressure in the range of 0 to 1.15 Bar. Logging rate from 1 minute to every 5 days and internal memory for 150,000 readings. The unit can also provide RS485 Modbus (5 second update rate), or SDI-12 (up to 1 second update), readings for connection to an external logger. Titanium body with Delrin nose cone in a 22mm diameter x 186mm housing with total weight of 160g. Operating Temperature range -20 to +80°C.

LL-QDKEY

£80.00

The LL-QDKEY  can be used to start data logging, set zero depth against surface level air pressure, check battery levels and check memory levels. Unit has a replaceable 12V Alkaline battery and can be used in place of a laptop in the field to simplify deployment of Leveline loggers.
