Let’s face facts; manual monitoring of cleanroom particulate counts is costly, monotonous and highly error prone. Cleanroom managers are very aware that by far the greatest contamination threats come from individuals entering controlled spaces. Understandably, to reduce the number people accessing these critical environments, many companies are tasking the cleanroom operations staff already working within these spaces with the additional responsibility for manual environmental monitoring (EM). While this approach has obvious benefits, such as lower labor costs and reduced contamination risks, it also introduces significant new data integrity issues.  

Setra’s wide array of non-viable particle counters are used throughout critical environments to measure particle concentrations of various sizes; these counters use a long-life laser diode, light scattering, and photo detector to calculate particle size and quantities as the sampled air passes through. Particle counters are required for cleanroom certification but are also often used for continuous, sequential, or periodic monitoring of the space between certifications and to ensure that particle levels are maintained below critical thresholds during manufacturing. This post will look at Setra’s different particle counters and their differences to help you decide upon the correct unit(s) for your application.

Setra’s comprehensive range of particle counters and air quality monitors are the most advanced, high-performance instruments available. This industry-leading position has developed from an enduring, intense focus on innovation and original intellectual property creation.

Setra Systems will be exhibiting at the AHR Expo in Las Vegas from January 31 through February 2. In addition to our extensive HVAC and Critical Environments lines, this year Setra will be unveiling several new and exciting products. Come by and see Setra at booth C5712!

Converting mA to voltage is common in HVAC when working with pressure transducers. Terminology to keep in mind includes:

• 1 mA = 0.001 AMP (short for amperes)
• Amps are referred to as CURRENT
• Resistor values are in OHMS (Ω is the symbol for ohms)
• VOLTAGE is the result of passing amps through a resistor

Cleanrooms are one of the most strictly regulated critical environments that require continuous monitoring. The most common cleanrooms are in compounding pharmacies, medical device manufacturers, and biotechnology facilities, as they need to guarantee the safety of their products for patients. However, a variety of other applications utilize cleanrooms to ensure accuracy, such as clinical research spaces, semiconductor manufacturers, and aerospace manufacturers.
