Waterproof Protection

The meter is enclosed in an IP67 rated waterproof casing and can withstand immersion in water at a depth of 1 m for up to 30 minutes.

Backlit Graphic LCD Display

These meters feature a backlit graphic LCD with  on-screen  help.  The  graphic  display allows for the use of virtual keys to provide for an intuitive user interface.

CAL Check™

Hanna’s CAL Check maintains a history of past calibrations and monitors the pH electrode and buffers during subsequent calibrations for any signs of wide variances due to a dirty or broken electrode or contaminated pH  buffers.  During  calibration,  users  are alerted to problems should they occur. After calibration, the electrode’s overall condition is displayed as a percentage.

Data Logging

The log-on-demand feature  allows  users to store up to 200 samples that can later be transferred to a PC with the HI920015 USB cable and HI92000 software.
