HI 4521

 and 

HI 4522

 are professional bench meters with color graphic LCD for pH, ORP (Oxidation Reduction

Potential), ISE (

HI 4522

 only), conductivity, resistivity, TDS, salinity and temperature measurements.

The display can be configured as a single channel or dual channel display in various modes: Basic information
only, GLP information, Graph and Log History mode.
The main features of the instruments are:
• Two input channels;
• Eight measurement parameters: pH, mV, ISE (

HI 4522

 only), conductivity, resistivity, TDS, salinity and

temperature;

• Manual selection, automatic and semiautomatic pH calibration in up to five points, with standard (1.68,

3.00, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) and custom buffers (up to 5 custom buffers);

• Manual Selection and Custom Standard ISE calibration in up to five points, with standard (up to five standard

solutions for each measurement unit) and custom solutions (up to 5 custom solutions), with or without
temperature compensation (

HI 4522

 only);

• Pure water checking using the USP <645> standard;
• Conductivity probe automatic recognition;
• Automatic or custom standard conductivity calibration in up to four points, probe offset calibration;
• One fixed point salinity calibration (Percent Scale only);
• AutoHold feature to freeze first stable reading on the LCD;
• Two selectable alarm limits (for pH, mV, ISE, conductivity, resistivity, TDS, salinity);
• Three selectable logging modes: Automatic, Manual, AutoHold logging;
• Up to 100 logging lots for automatic or manual modes and up to 200 USP reports, up to 100 ISE methods

reports;

• Selectable area and sampling period feature for automatic logging;
• GLP feature;
• Online and offline graph;
• User-friendly interface on large color graphic LCD (240 x 320 pixels);
• Opto-isolated PC interface via RS232, respectively USB.
