AS ONE AS-pH-22 LAQUA Twin Waterproof Portable pH Meter II
Product Description
The AS ONE AS-pH-22 LAQUA Twin pH Meter II is a portable, waterproof pH measuring instrument designed for precise and reliable pH analysis in research and industrial biotechnology settings. Featuring a measuring range from 0 to 14 pH with 0.01 pH resolution and ±0.01 accuracy, it employs the glass electrode method for electrochemical measurement. The device supports automatic temperature compensation essential for accurate pH readings in varying thermal conditions, a critical factor for bioprocessing and molecular diagnostics.
Key technical features include:
- IP67 waterproof construction, suitable for wet environments and field applications
- Advanced functions such as auto hold, auto stability, and auto power off for efficient operation and battery conservation
- Automatic standard solution recognition with options for NIST/USA standard selection, enabling compliance with laboratory calibration norms
- Temperature sensor adjustment function enhancing measurement accuracy
- Compact and lightweight design (164×29×20 mm, approx. 50 g), powered by two CR2032 button batteries
This meter is widely used in biotechnology research, clinical diagnostics, and biomanufacturing quality control, providing essential pH data for applications such as gene editing workflows, cell culture media monitoring, and synthetic biology experiments. Sold as a used unit, performance may vary from new equipment standards, and it is provided as-is.
Ideal for scientists and lab technicians requiring a durable, precise, and easy-to-use pH meter for laboratory and field use in cell imaging, fluorescence analysis, and molecular cloning environments.
