LDOPRO10 portable optical dissolved oxygen meter is designed for field water environment monitoring, waste water treatment plants, aquaculture, environmental monitoring stations, outdoor scientific sampling and river & lake patrol inspection. It serves field sampling technicians, environmental researchers and aquaculture QC specialists, solving drawbacks of traditional polarographic DO probes: electrolyte requirement, regular membrane replacement, slow response, hydrogen sulfide interference, inconvenient outdoor power supply, lack of portable storage protection and no automatic temperature/barometric/salinity compensation.
Adopting fluorescence optical sensor technology, it requires no electrolyte or replacement membrane and needs no warm-up after power-on. Equipped with 3.5-inch TFT color touch screen, IP57 high protection grade, robust POM housing and stainless steel probe guard, it adapts to harsh outdoor conditions including rain, mud and high humidity. Built-in rechargeable lithium battery supports Type-C fast charging, with functions of timed data logging, data hold, automatic barometric pressure/temperature compensation and 0–45ppt manual salinity compensation. Standard accessories include 3m long optical DO probe, charging cable and hard portable carrying case. Lightweight handheld design enables single-person long-time outdoor sampling and greatly cuts consumable replacement & maintenance cost for field testing.

Fluorescence optical DO sensor: No electrolyte, no sensor membrane, no warm-up on startup, immune to hydrogen sulfide interference; rare consumable replacement for long-term field use with ultra-low maintenance cost.
Ultra-fast response: Response time less than 15s for quick stable readings to boost efficiency during batch field sampling.
3.5-inch TFT color touch screen: Visual graphic interface with clear visibility under strong outdoor sunlight; simple operation allows new operators to finish calibration, sampling and data logging quickly.
IP57 high protection grade: Dustproof and splashproof for normal handheld operation in rainy, muddy and humid field environments without internal water damage.
Heavy-duty durable construction: Wear-resistant POM housing + stainless steel probe guard prevents probe breakage from collision or underwater dragging, suitable for rough field patrol work.
Multi-dimensional automatic environmental compensation: Built-in auto barometric pressure & real-time temperature compensation; 0–45ppt manual salinity compensation automatically corrects readings for seawater and high-salinity aquaculture water to guarantee accuracy.
Built-in timed data logger: Auto store readings at set intervals for unattended long-term water monitoring without continuous manual recording.
Type-C fast-charging lithium battery: Pre-installed rechargeable cell charged by common mobile phone cables, offering long endurance for off-grid field work without spare batteries.
Complete portable field kit: 3m extended optical DO probe for deep water sampling, Type-C charging cable and hard waterproof carrying case for full set anti-collision storage and easy transport.
Data Hold function: Lock stable readings on screen for manual on-site recording without value fluctuation from hand shake.

Pre-sampling assembly: Take out 3m optical DO probe and connect to meter port, check lithium battery level; charge via Type-C cable if power is low.
On-site calibration: Complete single-point auto calibration with standard clean water solution, input sample water salinity value to activate salinity compensation.
Field water sample test: Submerge probe into deep area of river or aquaculture pond; the unit automatically detects ambient temperature & pressure for compensation and outputs stable readings within 15s, press Data Hold to lock value for recording.
Timed auto logging: Enable timed data logger for long-term water monitoring; the device automatically store multiple data groups at set intervals without manual supervision.
Post-sampling storage: Rinse optical probe with clean water, wipe cable and main unit dry, store full set inside hard carrying case for dust & shock protection.

Key Factors to Help You Pick the Right Model

Usage scenario distinction: This optical portable model is preferred for long-term field work, aquaculture, river patrol and rainy on-site testing; benchtop DO meters are suitable for fixed lab bench testing.
Anti-interference demand: Optical probe is immune to hydrogen sulfide in sludge & waste water, delivering obvious advantages over traditional polarographic DO probes.
Long-term consumable cost control: Optical design has no electrolyte or membrane wearing parts; only probe replacement at end of service life, resulting in ultra-low annual maintenance cost, while polarographic probes require monthly membrane & electrolyte change.
Portable power demand for off-grid field sampling: Universal Type-C lithium charging eliminates the need to carry multiple spare batteries.
Deep water sampling demand: Standard 3m extended probe fits deep point measurement of lakes and aquaculture ponds without extra extension cable.
