The Setra SRIM2 is a non-BACnet room isolation monitor, built for cost-effective local monitoring and alarming in critical low differential pressure spaces like hospital isolation rooms, pharmaceutical cleanrooms, and laboratories. It’s built on the same structural foundation as the SRIM1, and it uses an onboard dead-ended low differential pressure sensor rather than a flow-through design, so there’s an absolute physical barrier that stops contaminated air from passing through the instrument itself.
In actual application, the SRIM2 shows room status on a 3-color backlit LCD screen (green, orange, red) so hospital or lab staff can tell at a glance if a room is safe, without needing to interpret numbers. It also alarms independently on high and low limits for pressure, temperature, and humidity, and it has a dedicated digital input for real-time door open/closed status. Output is a single analog loop, field-selectable via an onboard slide switch between 4-20mA or 0-5VDC/0-10VDC, so it drops into a standard BMS analog input.
From our experience, the 4-button membrane keypad is wipe-down and easy to sanitize, which matters in a clinical setting, and it lets a technician commission, calibrate, and configure the unit without special software. It mounts flush to the wall into a standard electrical back box, so there’s no custom enclosure needed at rough-in.
Before we quote this, we would normally check the pressure range you need (unidirectional or bidirectional), whether you need the auxiliary temperature or humidity analog inputs, and your door alarm wiring on site. Hope this helps.
