[features]
4.3 - Inch bright color screen, menu operation, simple and easy to get started;
The visual design:
A. automatic calibration, automatic cleaning, operation interface
B. measurement, calibration and cleaning process waiting time display interface
C. display scanning curve, easy reading analysis
- by anodic stripping voltammetry, low detection limit, accuracy and reliability;
The built-in zinc, lead and cadmium, zinc, mercury and arsenic ion detection method, direct call; upgrade to easily expand copper and other metal ion detection method by software;
It conforms to the GLP specification, support data storage, delete and check, the maximum storage capacity of 2000 groups. At the same time to ensure the data output to the SD card support;
Having standard USB communication interface and the REX data acquisition software, support PC connection and data output;
The IP65 protection grade, power supply, universal AC power adapter support and commonly used mobile phone charger with 4 support, 5 rechargeable NiMH batteries power supply, USB power supply, external mobile power supply, USB vehicle power supply for mobile measurement;
The supplies of independent development, complete the preparation, the cost advantage is obvious.
