1110 Benchtop pH Meter For Oxygen
Repeatable and trusted pH electrodes for the laboratory
pH is one of the most fundamental parameters that is measured in nearly every
application. However, there are different electrode requirements for different
applications. Due to these various requirements, YSI has a whole suite of
laboratory combination pH electrodes to choose from to ensure you select an
electrode that meets the demands of your application.
This electrode comparison guide provides a description of each component of a
pH electrode, an overview of each YSI lab electrode family, and specifications
for each YSI electrode. Please consult the YSI Laboratory pH Electrode
Application Guide for additional assistance in selecting a pH electrode and
the YSI pH Handbook for practical guidance regarding the measurement of pH.
pH Electrode Design
Choosing the right electrode for your needs begins with an understanding of
the different structures that make up a pH electrode.
Temperature sensor (optional):
Some electrodes feature an integrated temperature sensor. pH values are
dependent on temperature, so pH measurements should always be completed with
an accurate temperature sensor.
The shape of the membrane can vary in order to ensure optimal moistening.
Unique applications may require a specialized membrane shape.
YSI pH Electrode Families
YSI has three different families of combination pH electrodes from which to choose, each with unique characteristics. The IDS electrodes are designed for use with the YSI MultiLab, a multiparameter digital lab instrument. TruLine and Science electrodes feature BNC connection and are designed for use with the YSI TruLab, although they can be connected to the MultiLab via a BNC adapter.
MultiLab IDS
- Intelligent digital sensors (IDS) for the YSI MultiLab
- Store calibration status and serial number, even if disconnected from the meter
- Double-junction with Ag/AgCl reference system
- All electrodes have an integrated temperature sensor
- Available in gel-filled or liquid electrolyte versions; glass or plastic body
Science
- Designed for use in unique applications that require a particular junction
- Features the Silamid reference system, a unique construction of the Ag/AgCl reference system resulting in a more stable and longer lasting electrode with a fast response
- Double-junction reference and integrated temperature sensor
- Ground-joint junction with a fast electrolyte outflow is specifically designed for samples high in solids or with low ionic strength
- Platinum junction for applications that do not require a rate of electrolyte outflow as fast as the ground-joint
- BNC connector; compatible with any pH meter that has a BNC input
TruLine
- Designed for use in typical laboratory applications
- Single-junction electrodes with Ag/AgCl reference system
- Integrated temperature sensor option
- Durable electrodes with gel electrolyte for general use; liquid electrolyte sensors for more critical measurements
- Electrodes with special membranes for unique applications
- BNC connector; compatible with any pH meter that has a BNC input
YSI pH Electrode Comparison
The following comparison is designed to assist in selecting the electrode that best fits your needs. For additional information, the manual for each electrode can be found on YSI.com.
| Shape| Property/Application
---|---|---
| sphere (bulb)| constant quality, low resistance because of large surface
area, for most applications
| cone| robust, smooth, easy to clean, universally applicable
| cylinder| shock-proof, for general applications, especially useful for
fermenter electrodes
| spear| high resistance, suitable for penetrating semi-solid media
| flat| high resistance, shock-proof, easy to clean, suitable for surface
measurements
- Minimum immersion depth is the distance from the tip of the membrane to the outer junction. The junction must always be completely immersed when taking a measurement.
YSI calibration buffers are available in pH values of 4, 7, and 10.
| 3821 | pH 4 Buffer (box of 6 pints) |
|---|---|
| 3822 | pH 7 Buffer (box of 6 pints) |
| 3822 | pH 10 Buffer (box of 6 pints) |
| 603824 | Assorted Case (2 pints each of pH 4, 7, and 10 buffers) |
External temperature sensors are available for electrodes that do not have an integrated temperature sensor.
Potassium chloride (3 M KCl) solution is available (109 705Y) for refillable
electrodes.
3 M KCl is also the recommended storage solution for all YSI lab pH
electrodes.
YSI MultiLab
IDS (Intelligent Digital Sensor) pH electrodes feature a digital connector and
are designed for use with the YSI MultiLab, a multiparameter digital
instrument. A BNC adapter (108132Y) also allows these electrodes to be
connected to the MultiLab 4010-2W and 4010-3W.
YSI TruLab
The TruLine and Science pH electrodes feature BNC connection and are
compatible with any pH meter that has a BNC input, such as YSI TruLab meters.
The YSI Trulab can also make use of analogue ISE (Ion Selective Electrode)
probes with a BNC connector.
