Portable water testers (Handheld)

PH Testers

PH meter is a is a compact, battery-operated portable scientific instrument used to measure the acidity or alkalinity (pH) of a liquid. It is commonly used in laboratories, agriculture, aquariums, water treatment, food production, and environmental monitoring.

Features:

1. pH Electrode (Probe):

• The sensor that comes in direct contact with the sample.
• Usually made of glass with a sensitive membrane that reacts with hydrogen ions.
• May be replaceable or built-in, depending on the model.

2. Digital Display:

• LCD or LED screen showing the pH value.
• Some models display temperature as well.

3. Calibration Feature:

• Can be manually or automatically calibrated using standard buffer solutions (e.g., pH 4.00, 7.00, and 10.00).
• Ensures measurement accuracy over time.

4. Temperature Compensation:

• Automatic Temperature Compensation (ATC) adjusts pH readings for sample temperature.
• Essential for accurate results in varying environmental conditions.

5. Compact and Portable Design:

• Lightweight, easy to carry, often with a protective case.
• Ideal for fieldwork or on-site measurements.

6. Power Source:

• Typically powered by AA/AAA batteries or rechargeable lithium batteries.

Applications

• Water quality testing (e.g., drinking water, wastewater, pools)
• Agriculture & soil testing
• Food & beverage production
• Aquaculture and aquariums
• Environmental monitoring
• Education & research labs
