Benchtop Bicarbonate (HCO3-) Ion Meter | Water & Aquaculture Testing
The Benchtop Bicarbonate (HCO3-) Ion Meter is intended to quantify the amount of bicarbonate in aqueous samples in a scientific setting.
The device offers both p(HCO3-) measurement data and a direct readout of the bicarbonate concentration. The current PXS-HCO3-1 setup allows temperature correction between 5.0 and 50.0°C and covers a bicarbonate concentration range of 1.75 mg/L to 0.44 g/L.
It can be applied to laboratory research, ambient water testing, water quality analysis, and some aquaculture applications where bicarbonate concentration is a crucial indicator for assessing water conditions.
product key technologies
The Benchtop Multi-Parameter Bicarbonate Ion Concentration Meter is specifically developed and designed for detecting carbonate content in aqueous solutions. The instrument is highly suitable for various water quality control applications in power plants, enabling quality testing of water bodies such as steam, condensate, and boiler feed water. It can also be used in universities, research institutions, food processing enterprises, and other organizations, allowing professional and accurate measurement of carbonate ion concentration in water samples such as natural water sources, industrial process water, and industrial wastewater.
Bicarbonate Sample Preparation
Because bicarbonate is in equilibrium with carbonate and dissolved carbon dioxide, sample preparation can have a big impact on bicarbonate measurement.
Prior to measurement:
1.Gather a sample of representative water.
2.Steer clear of needless agitation and extended air exposure.
3.Verify the temperature of the sample.
4.Observe the guidelines for pH conditioning.
5.When the measurement process calls for it, add the suggested buffer or ISA solution.
6.Let the electrode system and sample reach the necessary measurement condition.
7.Once the reading has stabilized, take the measurement.
Additional sample preparation can be necessary for samples with atypical composition, high turbidity, high salinity, or severe chemical interference.

Features
- The PXS-HCO3-1 benchtop multi-parameter bicarbonate ion concentration meter is built around a microcontroller as the main control unit. The instrument has a low learning curve and is easy to operate, with a large digital screen presenting measurement data clearly and without error.
- The device is equipped with a dual-mode temperature calibration system, allowing flexible switching between automatic and manual temperature compensation. When an external temperature probe is connected, intelligent temperature adaptation is activated, with simultaneous real-time monitoring of the on-site temperature. If no probe is attached, the user can manually set the temperature parameters to perform compensation. The temperature probe is not a standard accessory; customers requiring this option should indicate it when placing an order.
- The unit can not only display the p(HCO3－) measurement parameter, but also directly read the bicarbonate ion (HCO3－) concentration data. With dual direct readouts, the detection process provides more comprehensive information.
- The overall design of the device is simple yet elegant. Its body is compact and lightweight, occupying little space and being easy to position and relocate.
Applications
1.Testing of Environmental Water
When assessing the chemical properties of natural and environmental water, bicarbonate concentration can offer helpful information.
When bicarbonate content is a component of the water-quality evaluation, laboratories can utilize the tabletop meter for controlled examination of collected water samples.
2.Water Testing for Aquaculture
In many aquaculture systems, bicarbonate plays a crucial role in alkalinity and buffering conditions.
Operators and researchers can assess bicarbonate-related circumstances in addition to other factors like pH, temperature, dissolved oxygen, and conductivity by using routine laboratory measurements to comprehend variations in water chemistry.
When samples must be transported to a laboratory for controlled measurement instead of depending solely on fast field screening, the meter is especially helpful.
3.Process and Industrial Water
Additionally, laboratory testing of process water, wastewater, and specific water-treatment applications can include bicarbonate measurement.
Natural water, industrial process water, industrial wastewater, power plant water, academic institutions, research centers, and food processing applications are already listed on the present product site.
FAQ
1.What is measured by a bicarbonate ion meter?
Its purpose is to measure the amount of bicarbonate present in water samples.
2.Are carbonate and bicarbonate the same thing?
No, despite their relationship through the carbonate equilibrium system, bicarbonate and carbonate are distinct chemical entities.
3.Why is the pH of the sample important?
The balance between bicarbonate, carbonate, and dissolved carbon dioxide can be impacted by pH changes, which may have an impact on measurement circumstances.
4.ISA: What is it?
Ionic Strength Adjuster is referred to as ISA. When the analytical process calls for it, it can be employed to create a more regulated ionic environment during electrochemical measurement.
5.What is the required number of calibration points?
The instrument's operating technique and the necessary measurement range determine how many calibration points are needed. Observe the calibration guidelines in the handbook.
