Lovibond SD 335 Multi multi-parameter handheld meter
If you are looking for a robust, precise and versatile instrument for professional water analysis, this handheld meter is the ideal solution. Thanks to its extensive range of functions and simultaneous measurement of temperature and two other parameters (pH, ORP, conductivity/TDS/salinity and dissolved oxygen), it represents a clear advantage for laboratories, waterworks and industrial plants. Similarly powerful is the [Lovibond Photometer MD 600], whose photometer technology also ensures precise results, making it a useful addition or alternative for water analysis.
Performance features and operation
This hand-held measuring device is primarily designed for high reliability and efficiency, with the galvanically decoupled measuring inputs enabling smooth parallel operation of different sensors. The intuitive menu navigation in up to seven languages facilitates daily use:
- Backlit LCD display
- Manual or automatic data logger
- Micro-USB connection for fast data transfer
- CE, RoHS and WEEE compliant design
- Rechargeable NiMH batteries (AAA)
- Highly resistant IP 67 protection class
- Practical protective armoring with two electrode holders
In addition, the ergonomic design stands out positively in any laboratory setting. The protective armoring enables use in hard-to-reach places without compromising measurement accuracy or safety. Two electrode holders, which are located on the side of the robust housing reinforcement, are used for this purpose and enable reliable results even in harsh environments.
Measurement data including time stamp and measuring point ID are saved for reliable documentation. They can be transferred directly to a computer as a CSV file via a micro USB cable - without any additional software installation. In addition, these data logs, which are generated automatically or at the touch of a button, ensure that process and quality controls remain traceable with little effort.
Certifications and standards
With IP67, the device meets a high protection standard for dust and water resistance, which is particularly impressive when working in damp or dusty conditions. As the device is also CE, RoHS and WEEE compliant, it meets the current European standards and directives. This not only ensures legally compliant use, but also demonstrates environmentally conscious and safe product design.
Concrete application examples
- Drinking water monitoring: regular testing of pH value, conductivity and dissolved oxygen in municipal waterworks to ensure that water quality is permanently guaranteed.
- Wastewater analyses: Thanks to reliable determination of redox potential and pH values, the wastewater treatment process in industrial and municipal plants can be optimally monitored.
- Aquaculture and fish farming: control of the oxygen content in the tank to ensure optimum living conditions for the fish.
- Industrial processes: Monitoring conductivity in cooling and process water circuits with simultaneous temperature measurement to increase the effectiveness and safety of technical processes.
Reliable measurement operation in demanding environments makes the system particularly valuable for operators or laboratories that want to obtain their analysis results quickly and efficiently. Substances such as calibration buffers for pH (e.g. pH 4, pH 7, pH 10), conductivity standards, oxygen electrolytic solution or redox electrode filling solutions can be used and calibrated with ease.
FAQs
How to clean the device
Simple surface cleaning with a soft, slightly damp cloth is usually sufficient. Aggressive chemicals or abrasive cleaners should be avoided to prevent damage to the protective armoring and display.
Can the hand-held measuring device also be used in corrosive liquids?
Yes, provided the corresponding electrodes are designed for this use. The robust housing design and IP67 tightness protect the device from penetrating liquids.
Which parameters can be recorded simultaneously
Up to three parameters (temperature and two others) such as pH, redox, conductivity or dissolved oxygen can be measured and displayed simultaneously.
How is the data transferred to a PC?
Recording can be started manually or automatically at the selected time interval. The measuring device is then connected via micro USB and the data is quickly transferred as a CSV file.
Conclusion
The versatile measuring instrument combines intuitive operation with precise and reliable measurements in a wide range of water analysis applications. Its robust design and protection class certification allow it to be used both on site and in the laboratory. The modular design with galvanically decoupled measurement inputs and the ability to measure several parameters simultaneously support efficient work. This model is an excellent choice for anyone looking for a handy and powerful all-round device in a professional environment.
