Hanna Benchtop pH Meter HI-2211

HI-2211 is a Benchtop pH meter. HI-2211 adds measurement for ion concentration (ISE) and Oxidation Reduction Potential (ORP) in the mV range. This instrument also features a reading stability indicator used during calibration and a measurement memory/memory recall function. Both instruments’ pH measurements are compensated manually or automatically for the temperature effect with the HI 7662 temperature probe. This meter has an easy-to-read LCD showing both the primary reading and ºC.

Easy and intuitive to use, the Benchtop pH Meter HI-2211 comes complete with several useful features, which make it particularly popular for frequent testing. Hanna Instruments manufactures the Best pH Meter in the World.

• Instructions 

The HI2211 has a separate input for a BNC pH electrode and thermistor 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 and ORP electrodes for their particular application. The separate temperature probe provides a high 0.5℃ accuracy measurement for precise temperature compensation.

Features at-a-glance of Benchtop pH HI-2211

Simple User Interface—Operation is simple, with limited features that require only the use of a couple of buttons. Readings are easy to view on the large, clear display.

One or Two-Point Calibration – Automatic calibration can be performed at 1 or 2 points using the 5 preprogrammed buffers (4.01, 6.86, 7.01, 9.18, and 10.01).

HI1131B pH Electrode – The HI2211 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 applications from samples with metals and Tris buffer to samples at elevated temperatures.

Temperature Compensation – The HI2211 offers automatic or manual temperature compensation of pH measurements over a wide range from -9.9 to 120.0℃.

mV mode – The HI2211 has a mV mode that can be used with a wide variety of ORP electrodes. The mV mode is also useful in checking the offset and slope of the pH electrode. Understanding the offset and slope characteristics helps know if the probe is functioning correctly.

Stability Indicator – The HI2211 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 HI2211 has a “MEM” button to store a reading. The reading can be recalled at any time by pressing the memory recall “MR” button.
