The INSIZE 0431-0018 Portable pH Meter is a reliable, professional-grade instrument designed for laboratory, industrial, and field applications. It provides accurate measurement of pH, millivolt (mV), and temperature readings, making it ideal for water quality testing, environmental monitoring, and chemical analysis.
Featuring a wide pH range of –2.00 to 18.00 pH and accuracy of ±0.01 pH, it ensures consistent, repeatable results. The unit also measures voltage and temperature, offering a complete solution for diverse testing needs. It supports NIST standard calibration buffers (pH 4.01, 7.00, 10.01) and offers both single- and dual-point calibration for precision control.
The ergonomic design includes a BNC connector for the pH electrode, a 4-pin probe connector, and a rechargeable battery for long-term field use.
