The HI2215 is an affordable pH/mV benchtop meter with 0.001 pH resolution. Operation is simplified to calibration, measurement range selection and a memory recall of logged data.
The HI2215 can perform up to a five-point pH calibration with seven standard buffers (1.68, 4.01, 6.86, 7.01, 9.18, 10.01, and 12.45) and two custom buffers. The HI2215 has two separate inputs for a BNC electrode and temperature probe. The BNC connector is a universal connector that is commonly available and allows the user to select from a wide variety of pH or ORP electrodes for their particular application.
The memory of the HI2215 allows for storage of up to 100 log-on-demand records and up to 500 interval logging records. Logged data, along with Good Laboratory Practice (GLP) data, can be recalled on the meter itself or transferred to a PC via USB cable.
Simple User Interface - Operation is simple with limited features that only require the use of a couple of buttons. Readings are easy to view on the large, clear display.
Automatic Calibration - Automatic pH calibration can be performed at up to 5 points using 7 standard buffers (1.68, 4.01, 6.86, 7.01, 9.18,10.01, and 12.45) and 2 custom buffers.
HI1131B pH Electrode - The HI2215 is supplied with the HI1131B glass body, double junction, refillable pH electrode with an indicating sensor made of High Temperature (HT) glass. The double junction and HT glass design allows the HI1131B to be used in a wide variety of application from samples with metals and Tris buffer to samples at elevated temperatures.
Temperature Compensation - The HI2215 offers manual or automatic temperature compensation of pH measurements over a wide range from -20.0 to 120.0°C.
mV mode - The HI2215 has a mV mode that can be used with a wide variety of ORP electrodes and for relative mV readings. The mV mode is useful in checking the offset and slope of a pH electrode. Understanding the offset and slope characteristic is helpful in knowing if the probe is functioning correctly.
Stability Indicator - The HI2215 features a stability indicator. An hourglass appears on the display when there is instability in the reading. The hourglass disappears once the reading has stabilized. At that time a reading should be taken or stored.
Measurement Recall - The HI2215 has a “RCL” button to review log-on-demand or GLP information on the meter display.
Data Transfer - Data can be transferred to a PC with a USB cable and HI92000 software (both sold separately).
