TV2 solution is a Low Cost solution.

Low cost does not mean inaccurate

The TV2 QuickCheck monitor uses state-of-the-art differential pressure (±0.002wg") temperature (±0.3°C) and humidity (±3.0%) sensors to check the environmental conditions every few seconds.  Each sensor comes with a NIST traceable calibration certificate.  The TV2 sensors are highly engineered and designed to maintain their accuracy for many years.  Each has excellent repeatability in addition to solid stability.  Each sensor his its own calibration table and analog to digital converter to ensure accuracty.

Quick to install and easy to use

The TV2 Cleanroom monitor is the most affordable, easy-to-use negative/positive isolation room monitor available anywhere.  Configuratin of the monitor is done via a menu on the touch screen, and takes just a few minutes. The TV2 Cleanroom monitor alarms, logs and charts all three critical environmental variables needed to keep your pressurized areas safe and within specs 24/7.  A glance at the QuickCheck digital display tells you immediately if everything is OK. 

Monitor, Alarm, Log and Chart

Clean RoomThe TV2 Cleanroom monitor is a temperature and humidity monitor and differential pressure monitor which also logs all three variables.  If either temperature, humidity or pressure begins to drift outside of the 'safe zone' that condition turns red, until the condition moves back into the safe zone. The TV2 cleanroom monitor also logs each of the three environmental conditions, differential pressure, temperature and humidity, every few minutes or so, far exceeding the ISO14644 requirement for all cleanrooms. Each variable is not only displayed so you know what the current conditions are but the logged data for each variable can be viewed on the screen or downloaded to a PC and printed out as a line chart.

The TV2 IV Room Environmental monitor alarm triggers a local audible and visual indication and closes a N/O dry contact relay to trigger an auto-dialer or loud external local-alarm if present if your alarm setting as exceeded. 

View the Logged Data on the Display or on a PC

A continuous chart is always available. It can be seen on the TV2 IV room monitor itself or on a any PC on the same network.  To see what happened last shift just touch any of the environmental variables or download the data to a PC with the free TView software.  You can zoom out or in to view trends or highlight individual readings.

Backing up the logged data to a PC

Once the TV2 is part of a Local Area Netwok all logged data can be automatically be backed up to the computer. A Chart can be viewed at any time. All logged data can also be exported into Excel. (This, however, breaks the 21 CFG 11 requrements.



Each sensor used by the TV2 IV Room monitor has been manufactured for accuracy and reliability.   Each sensor has a twenty-foot wire which plugs directly into the monitor, which can be extended to more than 200 feet to allow for remotely mounting the sensor from the monitor.  All data is transmited digitally to the monitor to insure accuracy.

  1. Temperature sensor -20°C to 80°C (±0.3°C)
  2. Relative Humidity sensor 0% to 100% (±3.0%)
  3. Differential pressure sensor ±1"wg (±0.002"wg)

No Maintenance  Fees or Labor

The TV2 monitor belongs to you and although the logged data can certainly be copied to any computer on the same network, or even the cloud, it does not cost you any extra to do so.  The data is stored in the TV2 monitor itself and can be copied to files on any PC in your network. And all alarms are initiated by your monitor and not from your network.
