Portable Pen Type pH Meter for Field Water Quality Testing
Handheld pH Tester with Temperature Measurement for Drinking Water, Aquaculture and Environmental Monitoring
Product Introduction
The KH.LPH-101 Pen Type pH Meter is a compact and portable water quality testing instrument designed for rapid on-site pH measurement in field and laboratory applications.
Unlike fixed online monitoring sensors, the KH.LPH-101 provides flexible handheld testing without permanent installation, allowing users to quickly evaluate water quality conditions in different locations.
Featuring a fast-response pH electrode and integrated temperature measurement, the portable pH meter provides accurate and stable readings for:
- Drinking water inspection
- Aquaculture management
- River and lake assessment
- Environmental field monitoring
- Scientific research
- Laboratory testing
Its lightweight pen-type design enables convenient operation for field technicians, researchers, and water quality professionals who require rapid pH analysis.
How It Works
The KH.LPH-101 measures hydrogen ion concentration in water through an integrated pH electrode.
The sensor converts chemical activity into electrical signals and displays the measured pH value together with temperature information.
This measurement method provides:
- Fast on-site testing
- Direct digital readings
- Temperature-compensated measurement
- Convenient field operation
