Core Highlights
- Long battery life: It has a huge lithium battery that can charge mobile devices, lasts a long time outside, and delivers real-time warnings when the battery is low or charging.
- High protection: The IP65 rating means it may be used in wet and muddy environments, and the protective cover for the instrument makes it even more robust.
- ± 1.0% F.S. measurement accuracy, automatic identification of reference solution makes calibration easier, and dual measuring mode works for a variety of situations.
- The 3.5-inch high-definition LCD screen is easy to use because the buttons are clear to see. You can also vary the lighting, which makes it simple to read at night.
Featured Applications
- Field environmental monitoring: on-site conductivity testing of surface water, groundwater, and soil leachate.
- Sewage treatment site: Rapid monitoring of water quality in each process section of the sewage treatment plant, without the need to bring it back to the laboratory.
- Industrial site inspection: spot checks on water quality at production sites in industries such as petrochemicals and mining smelting.
- Biopharmaceutical site: rapid on-site quality inspection of water and biologics used in pharmaceutical workshops.
Daily maintenance and precautions
Maintenance points
- Electrode maintenance: After the first use or long-term idle, it needs to be immersed in distilled water for several hours; Organic stains should be cleaned with warm water or alcohol containing detergent. Calcium and magnesium precipitates should be treated with 10% citric acid. Mechanical scrubbing of platinum black electrodes is prohibited.
- Instrument maintenance: Clean the shell with a damp cloth to avoid contact with strong acids and alkalis; When not in use for a long time, it needs to be fully charged before storage, and recharged every 3 months to extend the battery life.
- Calibration cycle: It is recommended to calibrate every 3 months, and shorten it to 1-2 months for frequent use or harsh outdoor environments.
Safety precautions
- Only use the standard power adapter of the instrument to avoid equipment damage caused by voltage mismatch.
- The electrode plug should be kept dry and clean, avoiding contact with acid, alkali, and salt solutions to prevent short circuits or measurement errors.
- When using outdoors, avoid dropping or colliding the instrument, and wipe off the moisture on the outer shell in a timely manner after use on rainy days.
- Do not disassemble the instrument or battery by yourself. Contact the official after-sales service for assistance in case of malfunction.
