New Upgraded LMS-PA200 Portable Fluorescence Dissolved Oxygen Tester Optimizes Field Water Monitoring Efficiency

Dissolved Oxygen Is The Core Basis Of Water Quality Management

Dissolved oxygen (DO) is the most essential testing indicator in freshwater aquaculture, mariculture, river and reservoir environmental monitoring, wastewater discharge supervision and laboratory water ecology research. Sufficient and stable dissolved oxygen can effectively avoid massive death of fish, shrimp and crabs, stabilizing farmers’ breeding income. For environmental supervision teams and testing institutions, real-time synchronized DO and temperature data is required to complete pollution source tracing, regular environmental inspection and discharge compliance acceptance. Laboratories also rely on precise dual-parameter data to support comparative aquatic experiments and research reports.

Fluorescence dissolved Oxygen Probes have gradually replaced traditional electrochemical electrodes in recent years, largely cutting frequent consumable replacement costs and solving the problem of unstable readings in seawater. Combined with long-term feedback from global field users, there are several functional experience optimizations we’ve introduced on the new LMS-PA200 to better fit modern digital monitoring demands:

1. Digital data archiving capability newly added The classic LMS-PA100 does not come with built-in data storage. Field staff need to record test data manually on paper, which brings extra workload when sorting standardized files for environmental inspections and project audits.
2. Optimized display with better outdoor readability The LMS-PA100 adopts backlit ink screen for basic field reading. The upgraded LMS-PA200 features a high-definition backlit LCD screen with higher contrast and visibility under strong sunlight and dark environments, bringing a smoother on-site reading experience.
3. Rechargeable power system for all-day field patrols The LMS-PA100 uses disposable batteries to support field measurement. The LMS-PA200 is equipped with a built-in 5200mAh rechargeable lithium battery with universal Type-C charging, delivering up to 30 hours of continuous operation and removing the need to carry spare batteries during long outdoor sampling missions.
4. Integrated Type-C port for charging & data transmission The LMS-PA200 innovatively integrates charging and data output into one single Type-C port, simplifying field wiring and reducing the number of spare cables carried during mobile sampling work.

New Upgrade Release: LMS-PA200, Iterative Version Of Classic LMS-PA100

We officially launch the upgraded LMS-PA200 portable fluorescence dissolved oxygen tester, fully inheriting the mature stable fluorescence probe core of LMS-PA100. Shared advantages of both models:

• Adopt self-developed consumable-free hard fluorescence membrane probe
• Support simultaneous dual-parameter testing of dissolved oxygen and water temperature
• Standard 3m probe cable, extended cables customizable on request
• Identical one-key automatic calibration operation
• Lightweight matte handheld body with customizable LOGO for bulk orders

The LMS-PA200 carries targeted experience upgrades to match higher-standard digital, long-duration outdoor monitoring scenarios.

Exclusive Upgrades on LMS-PA200

1. Consumable-free hard fluorescence membrane probe Adopts self-developed fluorescence probe without frequent membrane replacement. Fast response and ultra-stable readings even in seawater, completely cutting recurring consumable expenditure and reducing daily maintenance workload.
2. Dual waterproof structure for full-scene water body adaptation The handheld main unit reaches IP67 splash-proof rating, while the probe achieves IP68 deep submersible grade. It runs reliably in ponds, rivers, sewage and offshore seawater, effectively extending equipment service life.
3. Wide-range dual-parameter synchronous measurement Simultaneously test DO 0–20mg/L, saturation 0–200% and water temperature 0–50℃. One machine covers all testing standards for farms, sewage plants and labs. Both LMS-PA100 and LMS-PA200 support dual-parameter real-time monitoring.
4. 100,000-group large-capacity storage + integrated Type-C charge & data port Exclusive built-in storage saving over 100,000 groups of test data, supporting one-click export to PC via universal Type-C port for standardized digital archives. The unified Type-C port combines charging and data transmission to simplify field accessories.
5. 5200mAh large-capacity rechargeable lithium battery exclusive to LMS-PA200 3.7V built-in rechargeable lithium battery, continuous working time up to 30 hours; one full charge supports nearly one month of intermittent daily use. Compatible with mobile phone chargers and laptop USB ports, no special charger needed.
6. Identical one-key automatic calibration; upgraded high-definition backlit LCD screen with bilingual menu Calibration operation logic and one-key auto calibration function are fully consistent on LMS-PA100 and LMS-PA200. The upgraded backlit LCD screen delivers higher definition, stronger contrast and clearer readings under strong sunlight or dark night environments. Physical buttons are simple to operate; Chinese and English menu switching is built in, new staff can get started without professional training.
7. Lightweight compact body, standard 3M probe cable with customizable length Equipped with standard 3-meter probe cable, extended cables can be customized for deep water and offshore sampling on demand for both models. Mini matte lightweight body reduces fatigue during long-term mobile sampling in lakes, reservoirs and scattered breeding ponds, and LOGO customization is available for bulk orders.
