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
