Hangzhou Qiwei Instrument Co., Ltd. is one of the leading manufacturers and suppliers of portable multi-parameter nitrate 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 nitrate ion concentration meter in stock here from our factory. We also accept customized orders.
The nitrate (NO3-) concentration in agricultural and environmental samples can be quickly measured using the portable nitrate ion meter.
The device offers direct nitrate analysis using a nitrate ion selective electrode (NO3--ISE) for:
1.Extracts from soil
2.Water used for agricultural irrigation
3.Solutions for fertilizer
4.Nutrient solutions using hydroponics
5.Samples of the field environment
Farmers, agronomists, and researchers may do nitrate testing in the field without having to carry samples to a lab thanks to the handheld design.
Users may assess nitrogen availability, maximize fertilizer application, and enhance crop nutrient management with the aid of portable nitrate measurement.

Maintenance
The stability of nitrate measurements is enhanced by proper maintenance.
Following every measurement:
1.Use clean water to rinse the electrode.
2.Eliminate any leftover fertilizer or soil.
3.The sensor surface should not be scratched.
4.The electrode should be stored under the guidelines.
For extended use:
1.Carry out routine calibration.
2.Verify the stability of the electrode response.
3.Steer clear of long-term dry storage.
Frequent maintenance increases the electrode's service life and boosts the accuracy of field measurements.
FAQ
1.What is the difference between NO₃⁻ and NO₃⁻‑N?
NO₃⁻ stands for the total concentration of nitrate ions, while NO₃⁻‑N only reflects the nitrogen fraction contained within nitrate.
2.Can this nitrate analyzer process soil‑derived specimens?
Yes. It can carry out nitrate detection for soil, after users finish preparing soil extraction solutions.
3.What is the purpose of adding ISA during nitrate detection?
ISA works to stabilize the ionic strength of test liquids and improves result consistency across different specimens.
4.Does this instrument support outdoor measurement work?
It does. Its portable layout enables on‑site testing for agriculture‑related and environmental monitoring scenarios.
5.Are data storage and export functions available for nitrate test records?
Yes. Subject to the instrument's hardware setup, measurement logs may be stored and exported to conduct further data processing.
