Remote Airborne Particle Counters
Specialty Remotes
Photo-Remotes, Alternate Order

Small Footprint. Big Results.

The world’s smallest 1.0 CFM remote particle counter. Designed for any application you can throw at it. Our line of Remotes were built directly from customer feedback and those “special” applications that our customers challenge us with every day. So we built the world’s smallest 1.0 CFM remote particle counter to meet this challenge.

Built for Special Applications.

This unit is crafted to monitor environments remotely and accurately — enabling cleanroom, isolator, or constrained‑space sampling without sacrificing performance. Our Remotes are built with stainless steel enclosures, use a long‑life laser diode, and meet ISO 21501‑4 standards, ensuring reliability and compliance.

Remote 1104LD is an industry first laser diode based remote particle counter with a sensitivity of 0.1 μm at a high flow rate of 1.0 CFM (28.3 LPM).

Remote 5104V was designed to operate in CLASS 1 DIV 2 hazardous environments found in many challenging applications, and is compatible with VHP.

Real-Time Remote Data

ApexRp seamlessly integrates into existing facility monitoring systems (FMS) or building automation systems (BAS) for real-time data streaming, enabling prompt responses to any deviations from set parameters.

HEPA Filtered Exhaust

The ApexRp offers an internal HEPA filter traps >99.97% of particles ≥0.3 µm, ensuring the exhaust doesn’t compromise your controlled environment. Without filtration, this exhaust could reintroduce or spread particles back into the cleanroom.

Data Records

Effortlessly and securely store up to 3,000 particle count records. ApexRp provides real-time continuous data collection at a cost-effective price per point, ensuring unmatched performance, accuracy, and reliability.

VHP Compatible

Housed in a 304 stainless steel enclosure and compatible with rigorous decontamination methods—including vaporized hydrogen peroxide (VHP) sterilization—the ApexRp is ready for the most demanding environments.

Particle Monitoring for
Industrial Gas Applications

Contaminants in argon can affect its inertness, leading to unwanted reactions in processes where argon is used to create a stable, non-reactive environment. This is crucial in applications like shielding gases in welding or inert atmospheres in metal manufacturing.

Due to its small atomic size, helium is highly sensitive to particle contamination. Contaminants can affect its efficacy as a cooling medium in cryogenics and its purity in gas chromatography, impacting the accuracy and efficiency of these processes.

Particle contaminants in CO2 can affect its properties as a supercritical fluid, impacting its use in extraction and cleaning processes. In applications where CO2 is used for carbonation or as a refrigerant, purity is essential for both product quality and process efficiency.

Nitrogen is often used for creating inert atmospheres in various industries. Particle contaminants in nitrogen can introduce impurities into these processes, affecting everything from the quality of pharmaceutical products to the integrity of electronic components in semiconductors

In semiconductor manufacturing, impurities in ammonia can lead to defects in nitride films, affecting the performance of electronic devices. In chemical synthesis, contaminants can alter reaction pathways, leading to undesired products or yields.

Other Inert Gases Inert gases like neon, xenon, and krypton are used in specialized applications where their specific properties are crucial. Particle contaminants can alter these properties, thereby affecting the performance in applications like lighting, imaging, or as carrier gases.
