1. Core application: Global water quality monitoring, adapted to
meet the needs of multiple scenarios
This LoRa water quality calcium ion sensor is designed for
intelligent real-time monitoring of calcium ions in water bodies,
accurately covering multiple scenarios such as industrial
circulating water, drinking water treatment, aquaculture, boiler
water pipe control, surface water monitoring, RO membrane
pretreatment, etc. It can continuously detect the concentration of
calcium ions in water bodies 24 hours a day, effectively avoiding
equipment scaling and loss, ensuring the ecology of aquaculture
water bodies, and strictly controlling the water quality to meet
standards. It completely replaces the traditional manual titration
sampling mode, saves tedious manual operations, greatly improves
monitoring efficiency and data integrity, and helps upgrade the
intelligent control of water environment.
2. Flexible selection: Multiple configurations, adapted to various
deployment needs
The product supports multi range customization selection, covering
a range of 0.02~40000mg/L, perfectly adapting to different water
quality environments such as fresh water, seawater, industrial
wastewater, etc; Equipped with LoRa long-distance wireless
transmission technology, line of sight transmission can reach
several kilometers, requiring no wiring and easy deployment,
greatly reducing construction costs in outdoor, factory and other
scenarios. It has a high protection level of IP68 and can operate
stably in water for a long time. It comes with temperature
compensation and digital filtering functions, compatible with
RS485/Modbus protocols, and suitable for various PLCs and IoT cloud
platforms. It can also be equipped with solar power supply to
easily meet the monitoring needs of remote scenes without
electricity.
3. Hardcore advantages: high-performance support, stability,
durability, and easy operation and maintenance
Adopting high-precision ion selective electrode technology, the
detection response is fast, the numerical value is accurate, the
ability to resist water quality interference is fully utilized, and
the monitoring data is authentic and reliable; LoRa low-power
design significantly extends battery life and reduces maintenance
frequency in the later stages. Industrial grade wide temperature
operation design, suitable for complex working conditions of -10
℃~60 ℃, strong electromagnetic interference resistance, and stable
operation even in harsh environments; Real time cloud upload of
data, automatic triggering of alarms for exceeding standards,
CE/ROHS certification for the entire machine, excellent quality,
minimal long-term drift, and simple and worry free daily operation
and maintenance.
