Detailed information of HI98494 Hana original 12 parameter water quality analyzer:

Standard or rapid calibration-

Quick calibration can provide rapid single point calibration for pH, conductivity, and dissolved oxygen.
The standard pH calibration option can be used to select up to three calibration points from five standard buffers and one custom buffer.
Conductivity calibration is a single point selection of six standards or a custom standard.
Dissolved oxygen calibration can reach up to two standard points or one custom point.

Dedicated Help Key-

Always provide contextual help through a dedicated 'Help' key.
Clear tutorial messages and instructions are provided on the screen to quickly guide users through setup and calibration.
The displayed help information is related to the settings/options being viewed.

HI98494 Hana original 12 parameter water quality analyzer performance characteristics:

Backlit graphic LCD display-HI98494 features a backlit graphic LCD display with screen assistance, capable of displaying up to 12 parameters simultaneously. Graphic display allows the use of virtual keys to provide an intuitive user interface.
Waterproof protection-The probe adopts a waterproof housing with a protection level of IP67, which has an IP68 rating and can be continuously immersed in water.
Quickly connect digital probes-The HI7698494 probe has a quick connect DIN connector, which can be used for waterproof connection with instruments.
Replaceable sensor-By using on-site replaceable screw type connectors, sensors can be quickly and conveniently replaced. These connectors are color coded for easy identification of sensor ports.
Automatic sensor recognition-Sensors that automatically recognize the connection between probes and instruments; Any unused ports on the probe will not display parameters or be configurable.
automatic temperature compensation-The integrated temperature sensor allows for automatic temperature compensation for pH, conductivity, and dissolved oxygen measurements.
Automatic air pressure compensation-Equipped with a built-in barometer, it can compensate for dissolved oxygen pressure by selecting a unit for the user.
GLP data - allows users to view calibration data and expiration information with just one press of a button. Calibration data includes date, time, buffer/standard used for calibration, and slope characteristics.
data record-Allow users to store up to 45000 continuous or on-demand recorded samples, with recording intervals ranging from 1 second to 3 hours.
Bluetooth function and computer PC connection-Data can be quickly shared with other smart devices through the Bluetooth system, and recorded data can be transferred to a Windows compatible computer PC using the included HI920015 micro USB cable and HI9298194 software.
battery status-This instrument uses four 1.5V AA batteries, and there is a battery icon indicator light on the display screen that shows the remaining battery level

By using on-site replaceable screw type connectors, sensors can be quickly and conveniently replaced. These connectors are color coded for easy identification of sensor ports.
