Skill Scientific manufactures benchtop and portable pH meters for laboratory, field and industrial applications. From entry-level LCD models to high-precision instruments with ±0.001 pH accuracy, 7-inch touchscreen and GLP-compliant data printing — all designed and built in Shanghai since 1996.
Our benchtop pH meters are designed for laboratory environments where accuracy, data management and long-term stability are critical. The pHS series covers entry-level LCD models through to high-precision touchscreen instruments with up to ±0.001 pH accuracy, 1 to 5 point calibration, 1500-point data storage and GLP-compliant printing via USB and RS232.
Models include the pHS-2C and pHS-25 for routine daily measurement, the pHS-3C and pHS-3CT for 4.3-inch touchscreen operation, and the pHS-3, pHS-4 and pHS-5 for advanced laboratory and regulated environments requiring the highest available accuracy.
Our portable pH meters are built for on-site and field measurement without sacrificing accuracy. The pHB-7 features a 3.5-inch colour touchscreen, rechargeable lithium battery, USB Type-C connectivity and automatic temperature compensation from -5.0°C to 110.0°C. The pHB-4 offers the same ATC capability in a compact LCD body. For basic indicative readings, the pHC-2 and pHB-6 provide lightweight, simple operation at 0.2 kg.
Accuracy requirement — For pharmaceutical QC, precise buffer preparation or research applications, choose the pHS-4 or pHS-5 (±0.002 pH). For routine laboratory and water quality testing, the pHS-3, pHS-3C or pHS-3CT (±0.01 pH) are sufficient.
Laboratory or field use — If measurements are taken at a fixed bench, a benchtop model provides the best accuracy and data management. For on-site sampling, environmental monitoring or production line testing, a portable or handheld model is more practical.
Data and compliance requirements — If your laboratory requires GLP-compliant records, printed reports or LIMS integration, choose a model with USB/RS232 connectivity and data storage (pHS-3 and above, or pHB-7).
Temperature compensation — All pHS models support manual or automatic temperature compensation. If your samples vary significantly in temperature, choose a model with automatic temperature compensation (ATC) and an included T-820D temperature probe.
