Water Quality NH4 Ammonia Nitrogen Sensor

Product Model:NH4485


Product introduction

[Features]
◆ Integrated design, and built-in IoT transmission and sensor.
◆ IP68 submerged type and corrosion resistant material which can put into water without protective sleeve.
◆ It can be operated by delivery of current, and all functions are built-in.
◆ Ultra-low power consumption, it is suitable for large-scale deployment of green energy IoTs.
◆ The high-strength isolated cable can be put to use directly, and the signal is stable.
◆ The EC sensor is equipped with temperature compensation and measurement (in accordance with NIEA
W218.51C).
◆ The power and IoT communication are equipped with surge protection.
◆ With dual digital communication of RS-485 and Wi-Fi.
◆ Standard Modbus RTU and TCP protocols can connect to the global IoT.
◆ Wisdom design, storing parameter calibration, it can be installed directly on site after calibration.
◆ Operating with mobile web pages, it is convenient to on-site operation.
◆ Switching protective cover to standard solution cover on site, it is convenient for calibration.
◆ With 3-point calibration, and the calibration point can be set.
◆ During calibration and auto-cleaning, keep the last reading value to avoid misoperation, and it read the
state at the same time (calibrating/auto-cleaning/stabilizing).
◆ The latest thrice calibration records (date/slope) can be inquired.

[Applications] : Sewage, Seawater, Subterranean water, Aquaculture, River and lake detecting system
