Real Time Monitoring in Critical Areas

BioPharmaceutical grade, a 2-channel (0.5 µm and 5.0 µm standard) particle counter, which requires an external vacuum source. Users have the option of either 4-20 mA output, or RS-485 Modbus configurations. Comes standard with a 1 CFM Flow Rate. Other particle sizes, flow rates, and custom configurations may be available. In business for over 55 years, Climet has dozens of multi-jurisdictional patents in the field of particle counting. The CI-3100 RS Series is fully compliant with ISO 21501-4; PIC/S; FDA CGMP; EU GMP, Annex 1; ISO 14644-1/2:2015; 21 CFR Part 11, and others.

General information

The CI-3100 RS (Remote Sensor) Series is a 2-channel particle counter used in continuous monitoring applications in a variety of industries - generally Grade A or B (ISO 5) clean zones. The CI-3100 RS requires both an external vacuum pump and DC power. Users have a choice of standard data interface options including RS-485 Modbus, or 4-20 mA outputs. Alternatively, our CI-3100 OPT and CI-3100 Trident versions contain an internal power supply and vacuum pump eliminating the need of an external air source and vacuum tubing. Standard particle sizes are 0.5 µm and 5.0 µm, but custom sizes are also available. Designed for fixed continuous monitoring deployment, the CI-3100 RS offers a standard flow rate of 1 CFM, and some models are offered in an alternatively lower 0.1 CFM flow rate. On/Off functionality is remotely controlled, and additionally, the CI-3100 RS is VHP compatible ensuring easy cleaning and sanitation.

An expert in manufacturing industrial instrumentation, every new instrument design is drop and vibration tested ensuring end-users can expect up to a decade (and beyond) of reliable operation. This level of ruggedized testing is unique among other manufacturers, and ensures accidents don't turn into capital appropriation requests or expensive repair bills.

Accuracy and Stability of Measurement

A long-earned reputation in the industry for manufacturing the most accurate particle counters, studies confirm that Climet particle counters offer unparalleled repeatability (in metrological terms: stability or precision) of measurement. Over 50 years of manufacturing experience and use of the highest quality materials provides users unparalleled performance. High quality materials, an expert level of engineering acumen, and a mature DFM (Design For Manufacturability) virtually eliminate short-term and long-term calibration drift. This also enhances product life cycle, offering users a decade or more of reliable use. This is but one factor that greatly enhances Climet's reputation for providing the lowest TCO (Total Cost of Ownership). End users in regulated industries, and others of discerning taste for high precision instrumentation, exclusively sole source Climet as their preferred solution provider.

Interval Calibration Out-of-Tolerance Rates

Customers in regulated industries are generally required to re-calibrate their particle counter annually. Depending on the process or risk assessment, the CI-3100 may be calibrated at six month intervals, or even more frequently. When a particle counter is out-of-tolerance (OOT) during the interval calibration, a deviation report and investigation is required in regulated industries. Among pharmaceutical and biotechnology producers a simple failure investigation (assuming no batch rejection) costs between $8,000 to $12,000 on average. This cost is difficult to calculate as it's almost all labor and usually involves multiple departments. It is a hidden Cost of Poor Quality (CoPQ) associated with the instrument, which few end users track. As the cost of one simple failure investigation well exceeds the initial purchase price of a particle counter, we can conclude that CoPQ is the #1 cost driver. Internal studies and customer Total Cost of Ownership (TCO) feedback confirms that on average when a Climet particle counter is equal to or less than 7 years old, the instrument passes its interval calibration 99.6% of the time. In a separate internal study of 2,000+ Climet particle counters, it was confirm an in-tolerance rate of 98.3%, with approximately 25% of the particle counters included in this study being 10 or more years old. These statistics are absolutely unparalleled in the industry, and Climet uniquely provides value well beyond the simple use of the instrumentation.

Technical Brief

Exceeding standards and expectations.Climet uniquely manufactures our instrumentation, not to simply meet ISO 21501-4 standards, but to exceed the standard in order to meet user expectations for: (1) accuracy and stability of measurement; (2) mitigation of deviation reports and investigations; (3) ease of use; and (4) overall product quality. These factors uniquely provide our loyal customers the lowest TCO (Total Cost of Ownership).

Buy From An Innovator, Not An Imitator: Climet, literally, invented the portable particle counter (1993), as well as higher flow rates of 50 LPM, 75 LPM, and 100 LPM (2005-2008). With a long history of successfully implementing disruptive technologies, our customers can rest assured they own the highest quality instrumentation available on the market. Every Climet particle counter is manufactured with the highest degree of engineering acumen, and incorporates one or more patented or patent pending technologies.

Uncompromising Quality is in our Corporate DNA. Our success is not based on quirky marketing gimmicks, but rather rock-solid instrumentation that adds personal value, and that's time-proven and built to last a decade or more.
