QD631 dust and gas detector
The QD631 dust detector is an intelligent multifunctional gas detection instrument. The instrument adopts high-performance detection components and computer micro-control technology, combined with advanced SMD technology, and is manufactured with on-site sound, on-site flashing indicator lights and other functions. Real-time display and monitor the dust concentration on site.
The QD631 dust detector can convert the dust concentration signal in the air into an electrical signal for display and remote transmission. It adopts a three-wire 4-20mA or 4-wire RS485 output mode, which has the characteristics of long transmission distance and good anti-interference. QD631 dust detector is suitable for dust concentration detection in industrial environment.
