Digital pH Meter

1.Basic Identification Attributes

• Display: Digital LCD or LED with high-contrast, often backlit for readability in low light.
• Power Supply: Battery-operated (standard or rechargeable) or mains-powered for benchtop models.
• Measurement Range: Commonly 0 to 14 pH units.
• Form Factors: Pen-style, portable handheld, or fixed benchtop configurations.
• Connectivity: Some models offer USB, Bluetooth, or Wi-Fi data export.

2.Physical & Chemical Properties

• Accuracy: High precision—typically ±0.01 to ±0.1 pH depending on the model.
• Resolution: Up to 0.01 pH units.
• Calibration: Manual or automatic 1–3 point calibration with standard buffer solutions.
• Electrode Types: Replaceable or fixed glass bulb or ISFET (solid state) electrodes.
• Temperature Compensation: Automatic or manual, usually between 0–100°C.
• Casing: Often made from ABS or polycarbonate; some are IP67 waterproof rated.
• Environmental Tolerance: Operates well in ambient lab or field conditions.

3.Safety & Hazard Attributes

• Device itself poses minimal hazard—electrical safety applies (avoid contact with water in non-waterproof models).
• Electrodes may be fragile; glass probes can break and require proper disposal.
• Calibration and testing should avoid cross-contamination or exposure to hazardous chemicals.
• When used with aggressive chemicals, users must follow chemical safety protocols.

4.Storage & Handling Attributes

• Store in a dry, temperature-controlled environment.
• Keep electrodes moist in proper storage solution when not in use to preserve sensitivity.
• Clean electrodes with appropriate cleaning solutions based on sample type.
• Avoid mechanical shock, especially to glass probe models.
• Rinse probe with distilled water between uses to prevent residue buildup.
• Replace probes periodically depending on frequency and type of usage.

5.Regulatory & Compliance Attributes

• Manufactured in compliance with ISO 9001 and other quality assurance systems.
• Conforms to laboratory equipment standards for GLP and GMP settings.
• CE-marked and/or RoHS compliant models available depending on manufacturer.
• Suitable for regulated use in pharmaceutical, food, water testing, and academic settings.

6.Environmental & Health Impact

• Electronic device with minimal environmental emissions during use.
• Reusable, long-lasting tool reduces waste compared to disposable test strips.
• Proper disposal of electronic components and batteries required to reduce e-waste.
• Promotes environmentally responsible handling of chemicals through accurate pH control.
