Description
HI 112 and HI 113 are designed for those users that require the highest level of precision over the entire pH range. These meters are ideal for the most challenging applications where the sample pH may vary greatly.
Depending on the level of precision required for each application, the user can select the pH resolution as 0.01 or 0.001.
These meters maintain a high degree of precision over the entire measurement range; maximized when the automatic 5 point calibration is employed. Choose the most suitable buffers for your system from among 7 memorized values (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01, 12.45).
If the memorized buffer values are not the most ideal for your application, HI 112 and HI 113 will allow you to manually set 2 custom pH values for calibration.
These instruments also feature an extended temperature range (from -9.9 to 120°C), GLP functions, manual or automatic temperature compensation and an RS232 serial port for PC connection. All data can be downloaded and manipulated with the HI 92000 application software.
