Availability: InStock

This button-type benchtop multi-parameter water analyzer series has 4 models, supporting pH+conductivity, pH+dissolved oxygen, single conductivity and simultaneous pH+conductivity+dissolved oxygen testing respectively. It fits biotech, pharmaceutical, university education, food, environmental water quality and third-party testing labs for water quality QC, R&D sample detection, surface/aquaculture water monitoring and purified water testing.

It solves common drawbacks of traditional water meters: tiny display, fragile touch screen prone to water damage, complicated calibration, limited data storage, single export method and unstable readings affected by temperature, pressure and salinity. Equipped with 7-inch high-resolution white backlight screen, physical buttons deliver stable performance under humid lab conditions. It integrates intelligent functions: auto calibration, automatic temperature compensation and stable reading prompt, with storage capacity for 450 readings. Data can be exported via flash disk or wireless printer. A full set of plastic electrodes, calibration consumables and flexible adjustable probe holder are supplied as standard. IP54 protection class plus multi-dimensional auto compensation eliminate environmental interference to guarantee high repeatability of test data. One unit covers single/dual/triple water parameter testing to cut multi-instrument procurement cost. The durable button structure extends service life for long-term frequent bench operation.

7-inch high-definition white backlight screen: Clear readout under strong light or dim lab environment, soft white background reduces visual fatigue during long-time testing.
Physical button operation: More durable than water-sensitive touch screens, stable under splashes & high humidity with lower failure rate and longer service life.
Full intelligent auto routines: Auto calibration, full-range ATC auto temperature compensation, stable reading indicator and calibration completion reminder to cut manual supervision and human reading error.
Large on-board data storage: 450 independent readings stored locally to avoid accidental data loss during batch sample testing.
Dual data export modes: Flash disk local copy + wireless printer hard-copy printout, satisfying both electronic ledger and paper original record archiving demands.
Full environmental compensation system: Universal auto temperature & barometric compensation for all models; DO-integrated units add 0–45ppt manual salinity compensation for accurate seawater & high-salinity aquaculture correction.
Complete standard lab accessories: Flexible height-adjustable probe holder, power adapter, full plastic test electrodes, matching calibration buffer & DO membrane consumables included for out-of-box full testing without extra accessory purchase.
IP54 protection class: Resist minor bench splashes of reagent and water to extend service life on open lab workstations.
Optional multi-model matching: 4 versions precisely fit different lab test items without redundant functions to control procurement budget.

Model Matching Selection: LBPC100 for pH+conductivity only; LBPD100 for pH+dissolved oxygen; LBCD100 for single purified water conductivity test; LBPCD100 for simultaneous three-indicator batch sample testing.
Accessory Assembly: Mount matched test electrode on DF01 flexible height-adjustable holder, connect electrode cable to corresponding meter port, place magnetic stir bar inside sample beaker for homogenization.
Auto Calibration Routine: Enter calibration menu via physical buttons, immerse electrode into supplied calibration buffer; meter automatically completes 1/2/3-point pH or single-point conductivity calibration. For DO models, input sample salinity value manually to activate auto barometric & temperature compensation.
Sample Measurement & Reading: Submerge probe into water sample; the unit detects ambient temperature & pressure to apply automatic compensation, and triggers stable reading reminder once value stabilizes for manual record or one-click data storage.
Data Export & Archiving: After all tests, insert flash disk to copy all 450 archived readings; optional wireless printer can print hard-copy raw records on-site if required.
Daily Maintenance & Storage: Rinse electrodes after measurement; replace DO membrane caps & refill solution as needed for DO models, fold probe holder, wipe meter surface and store dust-free.
