PH mV Temperature Benchtop Meters

Details :

• The HI2211P is a basic, affordable pH/mV benchtop meter that features automatic calibration to 1 or 2 points with a choice of 5 preprogrammed buffers. All readings are automatically compensated for temperature variations from the supplied thermistor probe.

• The meter has a large, easy-to-read LCD that displays pH or mV and temperature simultaneously. The HI2211P is supplied complete with a pH electrode, temperature probe, calibration buffers, reference refill electrolyte, cleaning solutions, and a probe holder.
  
  • Large, Clear Display
  • Easy Navigation
  • Universal BNC connection

• The HI2211P is a basic affordable pH/mV benchtop meter. Operation is simplified to calibration, mode selection (pH or mV), and a last stored reading feature. The HI2211P has a selection to choose between pH and mV modes. The mV mode is used with an optional ORP electrode that is used to check the oxidation or reduction potentials of a solution. Hanna offers a variety of ORP electrodes from glass to PEI plastic body styles. The mV mode of the HI2211P is also useful in checking the offset and slope of the pH electrode. Understanding the offset and slope characteristic is helpful in knowing if the probe is functioning correctly.
• The HI2211P has a separate inputs 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 for a high 0.5°C accuracy measurement for precise temperature compensation.
• Ordering Information - HI2211P is supplied with HI1131BP pH electrode, HI7662 temperature probe, HI76404N electrode holder, HI70004 pH 4.01 buffer solution sachet, HI70007 pH 7.01 buffer solution sachet, HI7082 electrolyte solution, HI700601 cleaning solution sachet, 12 VDC adapter, and instructions.

Features at-a-glance

• 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.
• 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).
• HI1131BP pH Electrode - The HI2211P is supplied with the HI1131BP 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 HI1131BP to be used in a wide variety of application from samples with metals and Tris buffer to samples at elevated temperatures.
• Temperature Compensation - The HI2211P offers automatic or manual temperature compensation of pH measurements over a wide range from -9.9 to 120.0°C.
• mV mode - The HI2211P 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 characteristic is helpful in knowing if the probe is functioning correctly.
• Stability Indicator - The HI2211P 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 anytime by pressing the memory recall “MR” button.
