HI 2211: Benchtop pH/mV Meter with 0.01 Resolution ยี่ห้อ Hanna, Romania

Easy and intuitive to use the HI-2211 comes complete with a number of useful features which makes it particularly popular for frequent testing.

The HI2211 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 HI2211 is supplied complete with a pH electrode, temperature probe, calibration buffers, reference refill electrolyte, cleaning solutions, and a probe holder.
Display Large, Clear Display
Navigation Easy Navigation
BNC Universal BNC connection

Features:

  • Extra wide LCD displays pH & temperature
  • Standard pH range: -2 to 16pH with 0.01 resolution
  • Wide temperature range: -9.9°C to 120°C
  • On-screen step by step calibration guide
  • Calibration expiration reminder helps users make sure the meter is in optimum working order each and every time.
  • pH calibration with stability indicator makes process error free
  • Sturdy wide-based casing with easy to use buttons for quick efficient testing
  • Automatic temperature compensation
  • Measurement memory / memory recall function

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).

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 application 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°C.

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 characteristic is helpful in knowing 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 anytime by pressing the memory recall “MR” button.
