DESCRIPTION
pH/mV Bench Meter with Custom Buffers
Hanna Instruments HI 111
Description:
The new HANNA® bench meters, HI 110 and HI 111, are ideal for those users that need a higher level of precision in certain pH ranges.
Automatic pH calibration can be performed at 3 points, by choosing the most suitable buffers from among the 5 memorized buffer values (pH 4.01, 6.86, 7.01, 9.18, 10.01).
HI 110 and HI 111 will also allow the user to manually set 2 custom pH values for calibration most appropriate to you application range.
These instruments feature an extended temperature range (from -9.9 to 120°C), GLP functions, manual or automatic temperature compensation and mV measurements (HI 111 only).
