Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of portable multi-parameter bicarbonate ion concentration meter in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk portable multi-parameter bicarbonate ion concentration meter in stock here from our factory. We also accept customized orders.
Bicarbonate (HCO3-) in prepared aqueous samples can be quickly measured using the BXS-HCO3 Portable Bicarbonate Ion Meter during field sampling, hydroponic testing, aquaculture surveys, and other mobile water-quality applications.
The portable format, in contrast to a stationary laboratory instrument, enables operators to move the measuring system straight to the sampling site rather than returning each sample to a central laboratory.
The device has a pHCO3-range of 2.00–4.40, a bicarbonate measurement range of 2 mg/L to 0.6 g/L, and a mV measurement range of -1800 to +1800 mV.
Sample handling is a crucial component of bicarbonate measurement for field operations. To reduce changes brought on by gas exchange, temperature fluctuations, or extended storage, samples should be gathered and tested according to a standard protocol.
product key technologies
This portable multi‑parameter tester for bicarbonate ions is custom‑built to quickly determine HCO₃⁻ levels in water‑based solutions during outdoor and on‑site sampling work. Boasting a fully mobile form factor, the instrument needs no permanent mounting or complex peripheral hardware; it is lightweight and simple to transport to various test spots.
As an essential component of alkalinity in natural water bodies, bicarbonate concentration directly affects water quality stability, soil improvement efficiency, and process control of industrial water usage. Based on the ion selective electrode principle, this instrument delivers fast and reliable quantitative results of bicarbonate concentration in various water samples with straightforward operation procedures.
This portable multi‑parameter bicarbonate ion analyzer finds extensive use across multiple professional sectors. It supports water‑quality investigations for environmental monitoring agencies, assessment work for agricultural irrigation water fitness, alkalinity adjustment of aquaculture ponds, and water‑condition administration for boiler and circulating cooling water, alongside other research and industrial‑production applications. Featuring light weight and a robust housing, the instrument can cope with changeable outdoor operating surroundings. Its low‑energy battery setup enables non‑stop measurement throughout an entire working day.
Why Bicarbonate Samples Require Careful Field Handling?
The carbonate system in water is intimately linked to bicarbonate concentration. The equilibrium between dissolved CO2, bicarbonate, and carbonate species can shift due to variations in carbon dioxide exchange.
Because of this, the assessed condition of a water sample may be impacted by needless aeration, forceful shaking, extensive exposure to open air, or prolonged sample storage.
When doing field bicarbonate testing, operators should try to reduce the amount of time that passes between sampling and measurement.
The following handling techniques are advised:
Using a sanitized sampling container, gather the sample.
Steer clear of needless splashing or shaking.
If the measurement is delayed, keep the sample container closed.
Don't move the sample across different containers.
Samples should be measured as soon as possible after being collected.
When applicable, note the sample location and temperature.
For repeated field measurements, use the same sampling technique.
These procedures aid in minimizing preventable variations between the initial sampling condition and the measurement.

Field Protection and Handling
Portable‑style instruments are engineered for field sampling missions, where devices are likely exposed to dust, water splashes, and repeated transportation across different sampling sites.
To reduce the risk of hardware damage during outdoor measurement work, technicians are advised to use the official protective carrying case and operate the equipment within its specified working parameters.
Avoid marketing the device as waterproof or shock‑resistant, unless its official datasheet clearly states the corresponding protection grade and valid test prerequisites.

Is a Portable Bicarbonate Tester Right for Your Application?
When your workflow calls for it, select the portable BXS-HCO3 configuration:
1.Bicarbonate measurement on-site
2.Testing of agricultural water
3.Testing of hydroponic sources of water
4.Water surveys for aquaculture
5.Several places for sampling
6.Powered by batteries
7.Quick field screening
8.When necessary, follow-up laboratory verification
A benchtop bicarbonate ion meter might be more suitable for large-scale, centralized laboratory testing.
FAQ
1.Can bicarbonate be detected directly under field conditions?
Yes. This portable device is built for on‑site sampling and testing of prepared liquid specimens. Proper sample pretreatment and electrode preparation are essential to obtain trustworthy test results.
2.Why should bicarbonate‑containing samples be analyzed immediately after collection?
Sample manipulation and gas exchange will alter the carbonate balance in solution. Minimizing unnecessary agitation, aeration and storage time helps maintain stable sample status.
3.Can this instrument be applied to agricultural water testing?
Absolutely. The portable bicarbonate tester supports on‑site water‑quality surveys and evaluation of irrigation water for agricultural applications.
4.Is the instrument compatible with hydroponic systems?
It is capable of determining bicarbonate levels in eligible source water or nutrient solutions for hydroponics, provided sample concentrations fall inside the defined measurement limits.
5.Can it fully substitute laboratory titration analysis?
It cannot replace every laboratory titration method. Portable testing excels for rapid on‑site screening; nevertheless, standard lab titration is still required for certain official reports and result verification.
6.What are the instrument's measurable ranges?
The pHCO₃⁻ measuring span runs from 2.00 to 4.40, and the displayed HCO₃⁻ concentration covers 2 mg/L up to 0.6 g/L.
7.Is calibration required before field‑site measurement?
Definitely. Calibration must be completed following the electrode and instrument operation guidelines before routine detection.
