AELAB Pocket Testers are high-precision portable meters designed for rapid on-site water quality testing. With interchangeable probes, multi-parameter functionality, and optional Bluetooth connectivity, the series provides accurate and reliable measurements for laboratory, industrial, and field applications. Rugged IP67 construction ensures long-term performance even in harsh outdoor environments.
The instruments support pH, ORP, conductivity, TDS, salinity, resistivity, and temperature measurements with automatic temperature compensation. Multi-color backlight, low-voltage indication, and automatic data locking enhance usability and accuracy across routine testing workflows.
The AELAB Pocket Testers incorporate a replaceable probe system, allowing users to switch between PH1-S, ORP1-S, EC1-S, and PC1-S probes depending on the measurement task. The testers use high-precision electrochemical sensors with robust cell-based conductivity technology and glass or platinum electrodes for pH and ORP detection. The IP67 waterproof housing, locking ring probe interface, and 4×1.5V AAA power configuration ensure durability and field reliability.
The instruments analyze water quality using electrochemical potential measurement for pH and ORP, and cell constant-based conductivity for TDS, salinity, and resistivity. The built-in microprocessor stabilizes readings, performs automatic temperature compensation from 0–60°C, and locks data when stable. Bluetooth models transmit measurements to the AELAB mobile APP, enabling data logging, sample ID tagging, calibration reminders, and multiple display modes.
Bluetooth models synchronize with the AELAB APP for real-time graph mode, table mode, dial mode, general mode, sample ID classification, time-stamped logging, and calibration guidance. Data can be exported for GLP documentation and digital recordkeeping.
