HQ30D Portable Dissolved Oxygen and Conductivity/TDS Meter with Field Luminescent DO Sensor and Conductivity Cell, 5 m Cable

Designed for your water quality field applications to measure Dissolved Oxygen (DO) and Conductivity/TDS, the Hach HQ30D portable multi meter is a one channel advanced handheld digital meter that takes the guesswork out of measurements. The Hach HQD digital multimeter combines reliability, flexibility and ease of use. The HQD portable meters connect with a wide range of Intellical smart electrodes addressing different sample types and operating environment for water quality, environmental and treatment process purposes. The Intellical probe automatically recognize the testing parameter, store the calibration history, and method settings to minimize errors and setup time. In their Rugged outdoor version the Intellical sensors are nearly indestructible and available with multiple cable lengths.


Intellical™ LDO101 and CDC401 are digital, luminescent/optical dissolved oxygen (LDO) probe and Conductivity/TDS cell. These Rugged sensor versions are built with a stainless steel body ensuring sufficient weight to the probes 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 & CDC401 rugged models specially designed for field use. The LDO101 is fitted with an automatic pressure sensor module and a temperature sensor. The DO sensing cap comes with an iButton to track days in use and remind remaining life of the sensing cap element. The LDO101 and CDC401 Rugged are ideal for measuring dissolved oxygen and Conductivity/TDS/Salinity/Resistivity 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.
