TSI PresSura Monitors and Controls are the system of choice for hospital room pressure monitoring. For over 30 years, hospitals, laboratories, and cleanroom facilities have chosen TSI products for monitoring of their critical environments. TSI products are online in isolation rooms, protective environments, operating rooms, and other controlled areas. PresSura Room Pressure Monitors and Controls are also extremely effective for laboratory monitoring and cleanroom monitoring. By accurately measuring room pressure differential, ventilation rates (air changes per hour), temperature, and humidity, TSI products control the spread of contaminants in applications that matter.

Hospital Isolation Rooms
In Hospital Isolation Rooms and Operating Rooms, it’s all about safety. And when it comes to safety, you need reliable, accurate measurements for your applications. TSI’s unique pressure sensor, based on thermal anemometry, provides the most accurate results at the required 0.01 in. H2O (2.5 Pa) used in isolation rooms. HVAC pressure transducers simply can’t measure up. Typical pressure transducers use a membrane which is far less accurate and is subject to drift. When compared with a stable, accurate TSI Pressure Sensor, drift from a pressure transducer can impact the integrity of pressure readings, bringing into question the long term safety of specialized rooms in hospitals. Maintaining a pressure transducer’s accuracy requires frequent calibrations using expensive, dedicated calibration systems.

Laboratory Controls
Professionals working in laboratories need protection from potentially hazardous compounds. TSI’s direct measurement of critical parameters is a superior method of ensuring the safest laboratory possible. Specifically, fume hood controls maintain a constant face velocity needed to provide containment. An additional benefit of properly designed laboratory controls is energy savings. TSI laboratory controls are designed to safely reduce the exhausted air volumes, minimizing the cost of conditioning air supplied to laboratories. When designing laboratories, you need to consider room pressure, ACH, temperature, and room flow balance. Safety and design requirements are not identical for every laboratory. The wrong choice of lab controls could jeopardize safety, energy efficiency, or comfort on your laboratory projects. Great for new and retrofit projects, TSI Laboratory Controls provide you with the flexibility to design your lab the right way.
