Specifications
Product FAQ
Q. How accurate is your pressure sensor?
A. Our TV2 pressure sensor is accurate to ±0.002″wc
Q. Can the sensors be re-calibrated locally or do they have to be returned to the factory?
A. All sensors can be calibrated and characterized (adjusted) locally.
Q. Is your temperature/humidity sensor one or two sensors?
A. Our temperature/humidity sensors are combined in one sensor.
Q. How accurate is the temperature/humidity sensor?
A. The temperature sensors is ±0.5°C and the humidity part of the sensor is ±3.0% of ±1.5%.
Q. How far away can the sensors be located from the display?
A. Each sensor comes with a twenty-five foot wire, which can be extended so that the sensor can be positioned up to 200 feet from the display
Q. Can you see the differential pressure between the cleanroom and the anteroom and between the ante-room and the hall on the same monitor?
A. Yes. Each monitor can show the pressure from up to four sensors.
Q. Can I see negative and positive pressure readings on the same monitor?
A. Yes.
Q. Do I need different sensors for positive and negative pressures.
A. No. The same sensors can be used for either positive or negative pressures.
Q. Do I mount the monitor inside or outside the cleanroom?
A. It does not matter. Each sensor needs to plug into the monitor but the monitor can be mounted anywhere.
Q. How accurate are the sensors?
A. See the ‘Technical Details’ tab.
Q. Do the sensors need to be plugged into wall power?
A. No. Each sensors is powered by the monitor?
Q. How often is the display updated?
A. Every four seconds.
Q. How often is data logged?
A. This can be set to any interval between once a minute to once a day. Each sensor can have its own data-logging interval.
Q. Where should the temperature/humidity sensor be mounted?
A. It needs to be in what ever area is being monitored. Usually it is mounted in a corner of the room near the ceiling?
Q. Where should the pressure sensor be mounted?
A. The pressure sensor is a differential pressure sensor, meaning that it measures the difference in pressure between two rooms or areas. The sensor has twelve-inch two clear plastic tubes. Each tube is plugged into a passive port which is a small plastic plate with a tiny hole in the middle. Each passive port can be mounted on the inside of the ceiling of each area being compared. The sensor itself can be placed above the ceiling.
Q. How safe is the logged temperature, humidity, and pressure logged data?
A. Logged data is stored in non-volatile memory in the monitor. It can also be automatically backed up to a computer.
Q. Do you have iq/oq protocols for qualification of these units once installed?
A. IQ and OQ documents with check lists can be accessed on our website here: IQ, OQ Docs.
Q. If your SMS and Email TLS1.2 compliant?
A. Being TLS1.2 compliant is dependent on a couple of different things.
1. What version of .net framework is used to compile our TView software. We use the latest version of .net (4.7.1). This insures compliance.
2. The email and text alert portion of the TView software uses SMTP protocol. So if you are using your own SMTP server to do that, the compliance for TLS is based on the configuration of your server.

Turnkey Solution For Maintaining +/- Pressure
Monitoring positive and negative pressure is an essential component in efforts to help stop the spread of COVID-19 (SARS-CoV-2). The reasons for this are actually quite simple, however, the processes for creating and maintaining positive and negative pressure are very complex. Having an accurate and dependable monitor is essential.
Why pressure is important
It is very important to monitor and maintain negative room pressure, especially for patients quarantined for COVID-19. A room that maintains a negative pressure differential means that air inside the controlled space maintains a lower air pressure than the air outside the room. So, if you were to open the door to a negative pressure isolation room, you would feel a rush of air enter the room. This is important for patients with COVID-19 or any highly communicable disease because it goes a long way to help prevent the air contaminated with viruses from escaping where it could potentially affect others. Most hospitals have highly complex HVAC systems and filtration equipment that maintains this negative pressure, but things can always malfunction. This is why it is important to have a dependable and accurate monitor for negative room pressure.
In other cases, it is important to monitor and maintain positive building or room pressure. In hospital/surgical settings, the surgery room maintains a positive pressure differential. This means the pressure inside the surgery room is always greater than the exterior rooms. Pressure differentials can be very large or very minute; and are measured either in Pascals (Pa) or Inches of Water Column (“WC). The reason for the positive pressure is to protect the patient. Since the pressure in the surgery room. is always higher than the pressure outside the room, when the surgery door is opened, air will “rush” out, thereby preventing airborne contaminants such as viruses, bacteria or debris from entering. This is the same process used in cleanrooms to protect very sensitive electronics, microchips, or pharmaceutical preparations.
Unlike maintaining negative room pressure, which is typically only seen inside of hospital ICU’s, maintaining positive air pressure in office buildings, malls, grocery stores, daycares, etc. is very important to maintain the cleanest air possible. The fewer contaminants that are allowed to enter, the fewer the chances of a virus, bacteria or polluted air will affect those inside.
Most large retail stores, shopping malls, medical buildings, restaurants, etc. have an HVAC system that maintains positive pressure naturally. This is why many times, you will feel a rush of air when you open the door to enter. however, if the HVAC is not working properly, or there is a larger than usual traffic flow in and out of the building, those safe positive pressure levels can drop drastically. This leaves those inside at a greater risk.
With the TV2 Room Pressure Monitor, you will never have to guess if you are maintaining positive pressure, and protecting those inside.
Highly Affordable. Priceless Protection.
The TV2 Room Pressure Monitor can monitor two separate areas with the option for both wired and wireless sensors. If a pressure differential falls outside of desired threshold points, you will be notified by a local audible alarm, receive a text alert, and an automated email alert. Additionally, all data points are logged and stored locally and can optionally be charted to reveal exact times and instances where the issue occurred. This will provide valuable data to fix high traffic points, or increase HVAC productivity in some areas or at certain times of the day.
