Intellical LDO101 is a digital, luminescent/optical dissolved oxygen (LDO) probe. This Rugged DO sensor version is built with a stainless steel body ensuring sufficient weight to the probe for an easy outside handling, the sensing part is protected by a shroud, and the connection is ensured by strong and visible yellow coloured cable onto which you can clip depth markers (optional accessories), making the LDO101 rugged models specially designed for field use. LDO101 Rugged is available with a 5, 10, 15, or 30 meters cable. The LDO101 is fitted with an automatic pressure sensor module and a temperature sensor. LDO101 probes are fully calibrated at the factory. New LDO101 probes no longer require iButtons. The days in use tracking feature and the remaining sensor cap life reminder are initialized on the day of first use. The LDO101 Rugged is ideal for measuring dissolved oxygen in all type of external environment such as river, surface and ground waters, ponds, lakes, sea, wastewater plant, source water, drinking water reservoir for water quality, environmental and treatment process purposes.
