Using state-of-the-art Long Life Laser Diode technology, the Lighthouse Remote 1104LD is an industry first- a laser diode based remote particle counter with a sensitivity of 0.10 micron at a high flow rate of 1.0 CFM (28.3 LPM) that uses an optics and photodiode system designed to reduce or eliminate the temperature issues associated with high power laser diode sensors. 


Designed with reliability and quality in mind, the Remote 1104LD features our long-life laser diode technology that provides higher concentration limits, a better signal to noise ratio and requires less routine maintenance than conventional HeNe laser-based particle counters. 

The Remote 1104LD supplies continuous real time data at a cost-effective price per point. Very simple to integrate with large facility monitoring and management systems, the Remote 1104LD can transfer up to 8 channels of simultaneous particle count data via RS-485 MODBUS.
