TRRM Room Pressure Monitor

The TRRM is an advance compact control module that continuously monitors and/or controls room pressure and environment and also has the capability to report temperature and humidity. The TRRM incorporates a bright colorful touch LCD screen interface to display a room's pressure status along with its pressure reading accurate to 0.001" Water Column. This monitor / controller is designed to be either recessed or surface mounted wherever monitoring is required. The TRRM gives personnel a clear, accurate, and unambiguous indication of its environment and alarm status.

 The TRRM is capable of integration with building automation systems thru its onboard RS-485 Communication port or optional Daughter board.  All menus are accessed through the intuitive touch screen that allows the user to quickly configure for the TRRM to monitor and/or control critical rooms.

PCPM1000 Room Pressure Monitor

The AirShield wall mounted pressure monitor model PCPM1000 (w/ remote capability) constantly monitors the difference in pressure between a negative or positive pressure room and a hallway or other remote reference pressure site. It can control to a user specified negative or positive pressure set points.  It can monitor the room for alarm conditions, both audible and visual as required by the latest regulations. The PCPM1000-2 model is for sensing two sites simultaneously. The PCPM2000 model will be available in early 2008.

This Isolation Room Pressure Monitor/Controller constantly monitors the difference in pressure between two rooms or areas and maintains user specified negative or positive pressure set points. This unit can be used to control the room pressure with its PID output or simply monitor the room for alarm conditions.  The unit has the capability to communicate directly with Johnson Controls, Siemens and other Building Automation Systems including those systems using the LON (Local Operating network) communications protocol. 
  

The HMS1600 Fume Hood Face Velocity Monitor/Controller monitors face velocity air flow and maintains user specified face velocity set points. This unit is a precision measuring system for ultra low flows. The HMS1600 constantly monitors fume hood face velocity using through-the-hood sensing for positive feedback rather than conventional methods that rely only on exhaust air valve positioning. Fast acting electronic actuators and venturi air valves are also available.

A liquid crystal display provides a visual readout of face velocity in English or Metric units. Audible and visual alarms are provided to warn users when unsafe conditions exist. The HMS1600 is RS485 network ready and can also integrate into Johnson Controls Metasys.
