Pocket Multi-Parameter Pen Tester

• 4 differentiated pocket models for targeted selection: Single pH, single ORP, single conductivity, combined pH+conductivity to meet single/dual-index rapid testing demands across various industries.
• IP67 full dust & waterproof housing: The pen can be fully immersed in water for measurement; bench splashes and outdoor rain will not cause unit damage, ideal for rough field operation.
• Replaceable integrated composite probe: Only the worn probe needs replacement instead of discarding the whole tester, cutting long-term consumable expenditure.
• Multi-color backlight high-definition screen: Clear readout under dim or strong outdoor light with customizable backlight duration balancing visibility and battery life.
• Auto stable reading lock: Screen freezes once measurement stabilizes to avoid value fluctuation from hand shake for easy manual on-site recording.
• Multi-national calibration standards: 3 mainstream pH buffer sets (CH / USA / NIST) selectable to comply with lab testing regulations of different regions.
• Intelligent energy-saving system: Customizable auto shut-off timer plus low battery indicator to prevent accidental power drain.
• Complete factory-supplied consumable kit: Pre-installed batteries, calibration buffers, probe soaking maintenance solution, sample vials, lanyard and hard storage case for immediate out-of-box testing without extra accessory purchase.
• Compact pocket pen design: Small enough to carry in pocket for instant on-site testing at aquaculture ponds, production lines and rivers without bulky equipment transport.
• Full-range automatic temperature compensation: Universal 0~60℃ ATC eliminates manual correction for water samples with wide temperature variation for consistent accurate readings.

• Power-on preparation: Take out pocket tester and check pre-installed battery power, wipe probe protective cap; twist to remove worn probe for replacement with new composite probe if needed.
• Standard calibration: Remove probe sleeve, submerge probe into matched calibration buffer, select CH/USA/NIST standard via screen; unit automatically finishes 1/2/3-point calibration; conductivity models complete single-point calibration with supplied standard conductivity solution.
• On-site water sample testing: Fully immerse probe into test water; IP67 rating allows full submersion. The unit auto-detects temperature for ATC compensation and locks reading automatically once value stabilizes.
• Data recording: Manually record locked stable reading, adjust backlight duration for better outdoor visibility; auto shut-off activates during idle time to save battery power.
• Post-test maintenance & storage: Rinse probe with pure water after measurement, add 3.0mol KCl soaking maintenance solution and cover with protective cap; store full tester, calibration solutions, sample vials and lanyard inside 28.0×23.0×8.2cm hard carrying case.

• Key Factors to Help You Pick the Right Model
• Select model based on routine testing indicators
• Single pH acidity testing for water & solutions: LPHT1-Plus with 3-point multi-standard pH calibration, full pH buffers and probe maintenance liquid included;
• Exclusive ORP redox testing for electroplating & chemical waste water: LPORPT1-Plus supplied with dedicated ORP probe and 222mV standard calibration solution;
• Rapid TDS/conductivity/salinity screening for pure water & beverages: LPECT1-Plus streamlined single-conductivity pen ideal for pure water production line inspection;
• Simultaneous on-site pH + conductivity dual-index testing: LPCT1-Plus completes two measurements with one pen without carrying two separate testers.
• Usage scenario distinction
• Pocket portable rapid screening (aquaculture, beverage, production line patrol): All pen models with IP67 full submersion waterproof; benchtop meters recommended for precise fixed lab calibration.
• Calibration regulation matching demand
• Overseas export & multi-country lab testing: LPHT1-Plus / LPCT1-Plus support CH/USA/NIST 3 international calibration standards to comply with regional testing regulations; ORP & single conductivity pens adopt single standard system for domestic regular testing.
• Long-term consumable cost control
• Probes are replaceable separately instead of discarding the whole pen; full set calibration, maintenance liquids and sample vials pre-supplied to eliminate multiple separate consumable orders.
• Wide temperature sample compatibility
• Universal 0~60℃ full-range automatic temperature compensation for hot industrial effluent and cold beverage samples without manual temperature correction for consistent readings.
• Matching Application Scenarios for Each Model
• LPHT1-Plus (Single pH Pen): Aquaculture pond pH patrol, beverage QC, pure water rapid test and basic lab pH screening;
• LPORPT1-Plus (Single ORP Pen): On-site redox monitoring for electroplating waste water, chemical reagents and swimming pools;
• LPECT1-Plus (Single Conductivity Pen): Purified water production lines, bottled drinking water and simple seawater salinity screening;
• LPCT1-Plus (Combined pH+Conductivity Pen): Waste water treatment field inspection, comprehensive food raw material rapid test and multi-index sampling for small water plants.
• Target Buyers: Food & beverage processing factories, aquaculture farms, electroplating & chemical workshops, pure water equipment manufacturers, university basic labs, water treatment maintenance field staff, swimming pool water quality management organizations.

• Shockproof packaging solution: Thick rigid export carton with integrated shock-absorbing foam insert separating pen main unit, glass calibration liquid bottles and sample vials to avoid breakage & extrusion during long sea & land transit; bulk overseas orders can upgrade to solid wooden case packaging.
• Full set package contents: Matched IP67 pocket water tester main unit, pre-installed integrated composite probe, matched standard calibration buffers, 3.0mol KCl probe soaking maintenance solution, 30mL sample vials, pre-installed 4×AAA alkaline batteries, anti-lost portable lanyard, 28.0×23.0×8.2cm hard shockproof carrying case, operation manual, original factory quality certificate.
• Reference package dimension & weight: Single full-set outer carton 31×26×11cm, gross weight 0.9kg per unit.
• Lead time: In-stock standard models ship within 3–10 working days; custom probe specification & custom calibration liquid packaging orders take 15–30 working days.
• Logistics options: Sea freight, air freight and global door-to-door courier available for bulk complete overseas export of compact water testing equipment.
