Product Details
Online Dust Particle Counter KGD - OPC - 203
Product Introduction
The online dust particle counter KGD-OPC-203 adopts the principle
of optical scattering, which can accurately detect and calculate
the number of suspended particulate matters of different particle
sizes in the air per unit volume. It is equipped with the unique
intelligent dust source identification module of KACISE, and is
equipped with an air pump with a stable flow rate. It can
simultaneously output the particle numbers of six channels, namely
0.3μm, 0.5μm, 1.0μm, 2.5μm, 5.0μm and 10μm (the default unit is
pcs/m³, and it can be switched to pcs/L or pcs/ft³). The indication
error meets the JJF 1190 standard.
Product Features
- Intelligent particulate matter recognition algorithm to meet
accurate measurement in different environments.
- Industrial-grade laser with high reliability.
- Constant flow gas sampling system to ensure stable sampling.
- Can output the numbers of particles with sizes of 0.3μm, 0.5μm,
1.0μm, 2.5μm, 5.0μm, and 10μm (default units are pcs/m³, pcs/L,
pcs/ft³).
- Can display the quantity of each particle size, display level, and
alarm display in real time.
- Supports the correction of the standard source coefficient.
- Supports TCP/IP and MQTT protocols.
- Supports the unit switching among pcs/L, pcs/ft³, and pcs/m³.
- Supports the display switching between Chinese and English
interfaces.
- Wide operating temperature range.
- Temperature and humidity display.
- RS485 alarm light (optional).
