Multiparameter Probe AT-SB-PROBE-MP-P-C1
Datasheet
1. Introduction
The SENSBLUE RS‑485 Multiparameter Probe AT‑SB‑PROBE‑MP‑P is an online multiparameter self‑cleaning digital sensor introduced by the company. It adopts an integrated design, and the product is reliable and easy to use. Up to 8 parameters can be measured at the same time, with optional sensor types such as dissolved oxygen, COD, pH, ORP, conductivity/salinity, ammonia nitrogen, turbidity, etc. Using the RS‑485 bus and Modbus/RTU communication protocol, data can be directly transmitted to the acquisition platform.
The online multiparameter water quality sensor is equipped with an automatic cleaning device that allows setting the automatic cleaning interval and the number of cleaning cycles to match different water quality conditions. The automatic cleaning device can effectively clean the sensor surface, prevent microorganism adhesion, and greatly reduce maintenance costs. Each sensor is equipped with a quick‑plug waterproof connector, making assembly and disassembly easy. The front sensor protection cover prevents damage to the internal sensor. Slots around the protection cover effectively block large suspended particles and organisms from damaging the probe while maintaining measurement accuracy.
