The PC5000 Particle Counter/Portable Sampler has the capability to operate as both a grab sample particle counter (lab or field use) and an online particle counter, which makes it ideal for particle size and concentration analysis in a variety of municipal and industrial applications. The PC5000 can size particulates from 2 to 125 microns and count particulates from 2 to 750 microns. With the ability to detect particles at low part per trillion concentrations, the PC5000 offers superior analytical performance at an economical price compared to most other laboratory type particle counters.

Q & A’s

The PC5000 is a portable particle counter and sampler that can perform both grab sample and online particle counting, suitable for various municipal and industrial applications.

he PC5000 can size particulates from 2 to 125 microns and count particulates from 2 to 750 microns.

It is used for particle size and concentration analysis in water treatment, steam cycle monitoring, and filter performance optimization.

It operates using advanced electronics and a solid-state laser diode, with a user-friendly interface for both lab and field use.

The flow rate is 75 mL/min, and data is displayed graphically with up to 8 size channels shown simultaneously.

The device supports RS485 and USB for local communications, with MODBUS RTU and optional MODBUS TCP protocols.

The laser diode has a mean time between failures (MTBF) of 75,000 hours at 55°C.

It can store over 30,000 sample strings in online mode and up to 200 samples with 99 runs per sample in grab mode.
