Thank you for your interest in our smart and customizable Horiba WQ-300 series instruments.The high-quality digital multi-parameter handheld meters with their generous color LCD display with LED backlight (7 cm x 5.2 cm) are ideally suited for use in the field under all conditions and in direct daylight.Use our configurator to freely select the suitable measuring device of the WQ-300 Horiba series (1 to 3 channels), the measuring parameters (sensor cartridges) and desired cable length (with integrated sensor receptacle + digital module) according to your wishes and requirements. At a later stage, you can always connect another available measurement parameter to the device via the corresponding sensor cable or carry it in the case as a supplement. As with other handheld measuring devices from Horiba, a major advantage of these devices is that the measuring devices are highly resistant to shock, slipping and scratching thanks to a special rubber coating. Only four standard AA 2500 mAh batteries are required for operation, and to give you more flexibility when you are on the move, the WQ-300 series devices can also be powered by a powerbank or battery pack via the integrated USB interface. The IP67 certification, which certifies dustproofness and protection against temporary submersion for up to 30 minutes at a water depth of one meter, completes the overall professional package, along with the usual ergonomic design and ease of user operation.  Horiba attests to its outstanding product quality by offering a three-year warranty on the LAQUA WQ-300 series handheld meters. Other added values and features:During analyses, the user is supported by the display of operating instructions in the form of smiley icons, which is supplemented by an LED status display on the sensor. This is intended to prevent operating errors, which can lead to implausible measurement results. The design decision to install only a small number of control buttons and not to implement any nested user menus serves to ensure that the devices can be operated easily and safely even during discontinuous use as well as when used by other users.  The measuring instruments have an electrode wear indicator, a measuring stability indicator on the instrument and sensor, a locking function to "save" the currently measured value on the display, free naming of the measuring point (8 characters), automatic calibration functions, integrated sensor holders, self-diagnosis function, as well as GLP functions. The fold-out stand on the back of the instruments means that you always have your hands free to carry out your measurements easily and safely. Measurement data can be conveniently transferred to your computer or cell phone via USB or WiFi.All handheld meters of the 300 series are delivered in a reinforced measuring case for mobile use in the open air. This provides space for the meter, for electrodes and cables, for up to eight 60 ml bottles of buffer solutions including an integrated buffer solution bottle holder for easier calibration. Particularly noteworthy is the automatic sensor recognition of the instrument through the use of sensor cables with integrated digital sensor recording. Information about the sensor, calibration data as well as measurement settings are stored in the sensor recording and transmitted to the measuring instrument. In addition, calibration of all connected sensors is possible at the same time, since each sensor head independently stores the measurement and calibration data and transmits it to the WQ300 series measuring device.Optionally, there is the possibility to connect and use analog sensors via the Horiba BNC sensor adapter with the device, please contact us for this.Languages:GermanEnglishFrenchSpanishPortugueseChineseScope of delivery:WQ-300 series handheld meter in a carrying casethe digital electrode you have chosen, if applicable, and the corresponding sensor-specific cable with integrated digital sensor receptaclemanualManufacturer article number single measuring device WQ-310-K 1 channel: 3200832605 Note: Chloride sensor, if selected, is supplied without chloride ion strength regulator and chloride electrode filling solution.
