Moreover, they offer an extended temperature range from –20 ºC to 120 ºC
(-4 ºF to 248 ºF), using
HI 7662
interchangeable probes.
These instruments can also measure with ORP electrodes, thanks to their
capability to measure mV with a resolution up to 0.1 mV.
HI 98172
can also measure with ISE electrodes on ppm scale. The ion charge
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.
Other features include:
• Relative mV measurements
• Log on demand (50 samples on each range - pH, mV, ISE)
• Auto Hold feature, to freeze first stable reading on the LCD
• GLP feature, to view last calibration data for pH, Rel mV or ISE
• PC interface
