Specification

The HI 3512 instrument is a state of the art, professional bench meter with a graphic LCD, designed to provide accurate laboratory
results.

This instrument can also measure with ORP electrodes ( pH channel input) , thanks to their capability to measure mV with a resolution up to 0.1 mV and with ISE electrodes on ppm 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 solutions measurements. Relative mV feature is available as well as measurement in resistivity, TDS and salinity on the EC channel.

Two input channels are available.

Channel 1: pH/ mV/ ISE and temperature
Channel 2: EC/ TDS, NaCl/ resistivity and temperature

pH channel:

7 standard pH buffers ( pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01 and 12.45) for calibration
Up to 5 point pH calibration
Custom calibration with up to two custom buffers
Messages on the graphic LCD for an easy and accurate calibration.
Diagnostics to alert the user when the electrode needs cleaning
User selectable “ out of calibration range“ warning
User selectable “ calibration timeout“ to remind when a new calibration is necessary
