MODERN, EASY TO USE INTERFACE
There are two basic and advanced interfaces: with or without GLP information, real-time, and data logging.
COLOR LCD GRAPHIC DISPLAY
Graphic display, and customizable color configuration. The display allows real-time and virtual keys to provide intuitive user support.
TOUCH KEYBOARD
Capacitive touch keyboard for precise navigation of menus and screens. Capacitive touch technology ensures buttons never get stuck.
USB AND ETHERNET PORTS
USB-A connection for 2 keyboard input ports or USB drive
USB-C connection for 1 PC connection port and USB-C drive
Allows Wifi and Ethernet connections to upload and transfer data for storage or email.
REAL-TIME DATA RECORDING
– 3 recording modes available on HI6321 are: automatic, manual, and AutoHold.
– Manual and automatic recording up to 50,000 copies/file, storing at least 1,000,000 data points per user
– Automatic recording feature to save data by time and sampling interval.
AUTOMATIC CALIBRATION
– Automatic at 1 or 2 points 0% and 100% saturation or 0 mg/L and 8.26 mg/L
– Automatic at 1 point at % saturation or mg/L by user
– Standard calibration: 0 and 100% saturation
