In water quality monitoring, laboratory research, and industrial quality control, affordable yet precise pH/mV measurement tools are essential. The PH110B emerges as a standout entry-level solution, combining economic value with professional-grade features to meet the demands of routine testing across sectors like aquaculture, food processing, and environmental science. Weighing just 400g and sized 80×225×35mm, its portable design pairs with rugged performance, making it ideal for both benchtop and field use .
Core Design & Durability
1. Rugged Build for Versatile Use
The PH110B features an IP65 protection rating, ensuring dustproof and water-resistant performance—critical for harsh environments like wastewater treatment plants or outdoor aquaculture sites . Encased in durable plastic with a silicone rubber protective cover, it withstands accidental splashes and minor impacts during transport. A wristband assembly adds security for fieldwork, preventing drops when testing in ponds or industrial tanks .
2. User-Centric Power Management
Equipped with a rechargeable lithium battery (compatible with 100-240V AC adapters), the meter supports extended use between charges. Its auto-shutdown function offers 5 timing options (300 to 3600 seconds) or an off setting, minimizing unnecessary power drain . For added reliability, a power-off protection feature preserves settings and data during unexpected shutdowns, while the "restore factory settings" function resolves operational errors quickly .
Key Performance & Functionality
1. Precise Measurement Capabilities
The PH110B delivers accurate results across essential parameters:
-
pH Measurement: Covers -0.00~14.00 pH with 0.01 pH resolution and ±0.03 pH accuracy, spanning all acidic, neutral, and alkaline samples .
-
mV/ORP Measurement: Supports -1400.0~1400.0 mV range with 1 mV resolution and ±0.2% FS accuracy, suitable for redox potential testing in water treatment .
2. Calibration & Temperature Compensation
To maintain accuracy, the meter offers 1-2 point calibration with automatic NIST standard solution recognition—it identifies 4.01, 7.00, and 10.01 pH buffers instantly, simplifying setup . NIST standards are critical for traceability, ensuring measurements align with global metrology benchmarks used in industries from pharmaceuticals to environmental monitoring . Manual Temperature Compensation (MTC) corrects for temperature-induced errors, a necessity since pH readings shift with sample temperature .
3. Intuitive Operation
A 3.5-inch backlit LCD displays measurements clearly, even in low-light conditions like dimly lit labs or outdoor shade . The manual reading mode lets users control data capture timing, ideal for stabilizing readings in heterogeneous samples like soil slurries. Operation requires minimal training, making it accessible to technicians and hobbyists alike.
Included Accessories & Compatibility
The PH110B ships with a complete kit for immediate use:
-
E-201F pH Composite Electrode: A refillable probe with a BNC (Q9) connector, 0-14 pH range, and 5-60℃ operating temperature. Its polycarbonate housing resists corrosion, while the 3.0 mol/L KCl fill solution ensures stable responses .
-
Calibration Tools: Three 50ml vials of NIST pH standards (4.01, 7.00, 10.01 pH) and an electrode holder for storage .
-
Protective Gear: Silicone case and wristband for durability and safety .
Application Scenarios
1. Environmental & Aquaculture
Its IP65 rating and portability make it perfect for testing pond water in aquaculture (ensuring optimal pH for fish health) or monitoring stream acidity in environmental surveys . The mV function aids in measuring water redox potential, critical for assessing water quality.
2. Food & Beverage Industry
In food processing, the PH110B verifies pH levels in ingredients (e.g., dairy, fermentation broths) to meet safety standards. Its NIST-traceable calibration supports compliance with HACCP and QS certifications .
3. Laboratory & Education
For academic labs or routine research, it provides reliable data for chemical reactions, soil analysis, or student experiments. The easy calibration and durable design suit high-traffic educational settings.
User Value
As an entry-level instrument, the PH110B balances affordability with performance. It avoids the high cost of advanced meters while retaining critical features like NIST calibration, IP65 protection, and precise sensors. The included accessories eliminate hidden costs, and the 1-year warranty adds peace of mind .
