The HI3220 is a professional benchtop pH / ORP and temperature meter with a single input channel. The meter comes with a Hanna HI1131B glass pH electrode and a temperature probe to allow for automatic temperature compensation.
The HI3220 offers many features including CAL CHECK ™, five-point pH calibration, data logging, complete GLP data, and PC connectivity via USB to provide users with an easy way to organize and manage their data.
detalles
The HI3220 pH / ORP and temperature tabletop meter features CAL CHECK™, a clear and informative LCD display, data logging capability, and a USB port for computer connection. The HI3220 has a single input channel that allows for pH and ORP measurement. pH readings can be compensated manually or automatically for temperature variations with the separate HI7662-T temperature probe -20.0-120.0 °C.
The HI3220 can be calibrated up to five points with a selection of seven standard buffers or five custom buffers. All GLP data regarding pH and mV calibration is stored for user review when necessary.
Features at a glance
CAL CHECK ™ - Hanna's exclusive CAL CHECK ™ diagnostic system ensures accurate pH readings every time, alerting users to potential problems during the calibration process. The CAL CHECK ™ system eliminates erroneous readings due to dirty or defective pH electrodes or contaminated pH buffer solutions during calibration. After the guided calibration process, the probe status is evaluated and an indicator appears to inform the user of the overall pH electrode status.
HI1131B pH electrode - The HI3220 comes with the HI1131B glass body, double junction, refillable pH electrode with a sensor made of high-temperature glass (HT). The double junction design and HT glass allow the HI1131B to be used in a wide variety of sample applications with metals and Tris buffer at high temperatures.
Temperature compensation - temperature for pH measurements can be compensated automatically (ATC) or manually (MTC) -20.0-120.0 °C using the supplied HI7662-T temperature probe.
Automatic Calibration - pH calibration can be performed up to five points with standard buffers seven and five custom buffers.
GLP data - Calibration data for each channel including date, time, standards used, offset, and slope can be accessed at any time through the HI3220 menu.
Data logging - The log-on-demand function allows a maximum of 200 data points you wish to record. Up to 600 data points can be recorded when using interval logging, which allows the user to specify time intervals from 5 seconds to 180 minutes.
Data transfer - with a built-in logging function, measurements are stored in non-volatile memory and can be transferred to a PC via the USB port using the optional HI92000 software and HI920013 USB cable (both sold separately).
