    Hach Hach Intellical Rugged LDO Sensor 10M Cable for HQ Meters

    Luminescence-based LDO technology - no replacement of electrolyte, no interference by deposits or H2S 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. Hach Intellical LDO is a revolutionary breakthrough in the measurement of dissolved oxygen, eliminating the numerous reliability and maintenance concerns inherent of older DO measurement technologies. Intellical Rugged digital probes can reliably test in the harshest environmental conditions Intellical digital probes provide ultimate traceability in measurement history Intellical digital probes alert the user when re-calibration is needed Intellical digital probes can be moved between meters without the need to re-calibrate or re-enter measurement settings

    YSI YSI ProDIGITAL ODO/CT Cable Assembly (10 metre)

    The ODO/CT, probe and cable assembly features integral (i.e., built-in) optical dissolved oxygen, conductivity, and temperature sensors and is available in lengths up to 100 meters. It’s perfect for measuring DO in the following applications – estuary, wetland, coastal, aquaculture, or any application requiring accurate, real-time salinity-compensated DO measurements. The ODO/CT assembly is compatible with the ProSolo, ProSwap, and ProDSS handhelds (sold separately). Pre-assembled ProSolo kits are available The ODO/CT has all the advantages of optical dissolved oxygen technology – higher accuracy, less maintenance, no stirring required for accurate measurements, holds calibration longer than membrane covered sensors and is not susceptible to interferences from other gases. Instrument setup is quick and easy with the integral sensors, which eliminates the need to install sensors before use. The digital technology of the ProDSS allows the handheld to automatically recognize connected sensors, so there is no need to tell the instrument what is connected.  The ProDIGITAL ODO/CT probe and cable assembly features include: Integral (i.e. built-in) optical DO, conductivity, and temperature sensors that are auto-recognized by Pro Series handhelds, reducing instrument set-up time Automatically compensates DO mg/L measurements for salinity; no need to enter salinity compensation values Rugged Optical DO sensor cap with a 2-year warranty is pre-installed on new assemblies Fits in a 1 inch well
