The HI5421 is an advanced research grade benchtop Dissolved Oxygen and BOD meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity. The HI5421 is rich in features including data logging, alarm limits, comprehensive GLP, and more while retaining simplicity in use with both dedicated key for routine operation and virtual keys that guide the user through setup options. Capacitive touch keypad Built in Barometer for automatic pressure compensation BOD, OUR and SOUR methods The HI5421 is an advanced research grade benchtop dissolved oxygen and BOD meter that is completely customizable with a large color LCD, capacitive touch keys, and USB port for computer connectivity. The HI5421 is supplied with the HI76483 Clark-Type Polarographic probe that measures a wide range of dissolved oxygen from 0.0 to 600% saturation and 0.00 to 90.00 mg/L (ppm). The HI76483 is only 12 mm in diameter and has a built-in thermistor temperature sensor that compensates for temperature variations from 0 to 50 oC. The HI5421 can be calibrated automatically to two points (0% and 100% saturation or 0.00 mg/L and 8.26 mg/L) or to a user-defined value. The calibration data including date, time, and calibration points can be accessed at any time along with the current measurement by selecting the Good Laboratory Practice (GLP) display option.
