Hanna Instruments HI3512-01 Two Channel, Benchtop pH/ORP/ISE, EC/TD/NaCl/Resistivity Meter







Hanna HI3512 is a two chnnel professional benchtop meter with a graphic LCD, designed to provide accurate laboratory results. Channel 1 features pH/ORP/ISE and temperature measurement capability while channel 2 measures EC/TDS/Nacl/Resistivity and temperature. The pH channel offers up to 5 point ph calibration with 7 standard buffers(pH one point sixtyeight, four point zero one, six point eightysix, seven point zero one, nine point one eight, ten point zero one, and twelve point forty-five) and up to two custom buffers. Hanna's exclusive calibration Check  diagnostics system ensures accurate pH reading every time by alerting users of potential problems during the calibration process, The calibration Check system eliminates erroneous readings due to dirty or faulty pH electrode or contaminated pH buffer solutions. After the guided calibration process, a probe condition indicator is displayed on the LCD informing the user of the overall pH electrode status. Hanna HI3512 can measure using ORP electrodes(pH channel input), Thanks to its capability to measure mV with a rosolution up to zero point one mV and ISE electrodes on part per million scale(pH channel input). The electrode type and unit selection capability and the ISE calibration in up to five calibration standard solutions make this instrument very useful for a large range of concentration solution measurements. The EC channel offers up to two calibration points with seven memorized standards(0.00 microsemen, eighty-four microsemen, one thousand four hundred and thirteen microsemen, five microsemen, twelve point eighty-eight microsemen, eighty microsemen, 111.8 microsemen). The EC channel supports autoranging, manual ranging and lock of the user selected range. temperature compensation selection, temperature reference selection( fifteen degree celcius, twenty or twenty-five degree celcius) and temperature coefficient set.
        pH and EC channels also provide user selectable"out of calibration range" warning and a "calibration timeout" to remind the user when a new calibration is neccessary.
        Messages on the graphic LCD offer directions for easy and accurate calibration for both channels as well as diagnostics to alert the user when calibration or measurement issues are detected. Other special features of Hanna HI3512 such as log-on demand of up to four hundred samples, automatic logging interval with log on stability feature of up to six hundred records, auto HOLD the freezes the first stable reading on the LCD display, GLP to view the last calibration data for pH, rel mV, ISE, EC or NaCl and PC interface vis USB.
