With a quick response time, excellent calibration stability and long instrument life, the outdoor versions function efficiently even under the most difficult conditions. With digital data transfer, cables can be as long as 30 m, allowing the electrodes to be used in previously inaccessible locations, e.g. wells and bridges. Ingeniously simple: O 2 measurement without calibration The optical measurement principle of the LDO sensor (luminescent dissolved oxygen) has revolutionised O 2 metering. LDO sensors do not contain a membrane, and are therefore not susceptible to the risk of becoming blocked. Instead of frequent calibrations and changes of electrolyte, the sensor cap has to be replaced just once each year. Using LDO sensors saves time and money from day one, in each and every application. 3
➔ Laboratory automation: see Chapter 9 ➔ Samplers: see Chapter 10 ➔ Process measurement technology: see Chapter 11-20 Clear display: visual and sound notification of stable readings HQD uses plain English HQD has an intuitive user interface. The illuminated display is clear and legible. The well organised menu structure is immediately understandable and user friendly. Ensuring smooth, error-free handling for single measurements or for complex tasks. GLP-compliant data management, also in the field: all the settings for each measurement are saved Need to calibrate? HQD lets you know! The appropriate calibration interval for the application is defined just once, and HQD faithfully reminds you when the next calibration is due. Furthermore, you can also define the quality individually by entering specifications for the slope. HQD INTELLICAL electrodes/sensors All standard INTELLICAL electrodes/sensors are <strong>water</strong>proof down to a depth of 3 metres for 24 hours, including temperature sensor. All outdoor INTELLICAL electrodes/sensors are <strong>water</strong>proof down to a depth of 30 metres for 24 hours, including temperature sensor, steel housing, with reinforced cable.
