Feature: 1. [Industrial Grade] Particle dust transmitter is sieved by the unique data dual frequency acquisition technology, which results in the number of particles of equivalent particle size per unit volume and its mass concentration is calculated by a scientific and unique algorithm. 2. [High Accuracy] The sensor of particle dust sensor is accurate to 1ug/m³, PM2.5 and PM10 output simultaneously, with advanced anti attenuation technology to ensure long term stability. 0‑1000ug/m³ measurement range, dual frequency data acquisition and auto calibration technology, consistency up to ±10%. 3. [Stable And Waterproof] This air quality transmitter adopts wall mounted shell type design, with IP65 protection level, unique waterproof treatment, fearless of dusty environment, strong anti interference, suitable for all kinds of industrial places. 4. [Premium Probe] In high humidity places, when the temp drops will produce condensation, water droplets attached to the sensor, seriously shorten the service life of the probe. We use a waterproof and dustproof probe, even if put into boiling water, it will not be damaged. 5. [Widely Used] High accuracy air quality monitor can provide industrial grade PM2.5, PM10 monitoring. It is suitable for use in outdoor weather stations, dust monitoring, industrial plants, libraries and other environments. Easy to use with simple wiring and installation.

Package List: 1 x Particle Dust Transmitter2 x Screw2 x Expansion Tube Note: Common troubleshooting:1. PLC cannot collect dataA: Please check the output type of the device; whether the device is turned on.2. The collected signal differs greatly from the actualA: Please check the equipment range and data conversion relationship.3. Transmitter output jumpsA: The distance between transmitter and collector is too far, resulting in signal disorder.4. How to quickly determine the problemA: Temporarily without post acquisition equipment, multimeter measurement of transmitter signal output.
