Protection & Compliance

The TV2 cleanroom monitor uses a state-of-the-art differential pressure sensor along with a temperature/humidity sensor to sample the environmental conditions every few seconds.  If any environmental condition changes and drifts outside of the specified 'safe zone' the QuickCheck display sounds the alarm and that condition turns red, until the condition clears. 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.

Monitor pressure, temp and RH of any negative or positive pressure room

The TV2 Cleanroom monitor is the most affordable, easy-to-use negative/positive isolation room monitor available anywhere.  The TV2 Cleanroom monitor alarms, logs and charts all three critical environmental variables needed to keep your Cleanroom safe and within USP 797 and 800 specs.  A glance at the QuickCheck digital display tells you immediately if everything is OK. 

As long as all the numbers are green everything is fine.  If any condition becomes unsafe the font turns red immediately.  If a delay time has been set an alarm sounds once that variable has exceeded its delay time.

Mount it at the cleanroom entrance to provide an instant check to each employee before he enters. The differential pressure sensor is customized for the pressure range of ±1"wc and is accurate to ±0.002"wc.

Monitor, Alarm, Log and Chart

Clean RoomThe TV2 Cleanroom monitor uses very accurate differential pressure 'sensors and temperature/relative humidity sensors.  Pressure and temperature/rh is not only displayed so you know what the current conditions are but data is logged for each variable.  The logged data chart can be viewed on the screen or downloaded to a PC, printed out as a line chart, or exported to Excel

The Cleanroom Monitor high/low alarm for each condition triggers an audible and visual indication if any environmental condition become unsafe. In addition, the relay closes to trigger an auto dialer or loud external local-alarm if present.

The secure TView alert software initiates an email or text alert anytime an alarm occurs so the user immediately knows a problem has occured.  The TV2 Cleanroom monitor uses your own Local Area Network and its connection to the internet to access an email server and deliver a text or email to multiple persons.

Store and display data history

A continuous chart is always available.  It is not necessary to downloadClean Room your logged data to see a graphic depiction of the condition history.  To see the temperature, humidity or differential pressure history of the Cleanroom just touch the variable you want to view.  A chart showing the logged data immediately appears.  Over 1.5 years of history is saved and can be scrolled through you if you have set the logging interval to every ten minutes.  You can zoom out or in to view trends or highlight individual readings.

Each sensor used by the Cleanroom monitor has been selected for accuracy and reliability.   Each plugs directly into the monitor with a four conductor jack.  Although each can be positioned up to 200 feet away from the monitor, it still delivers accurate readings.  Each value the sensor reads is converted to a digital signal before being transmitted back to the display to ensure the reading is accurately transmitted for logging and displaying.

  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 Cleanroom monitor belongs to you and although the logged data can certainly be copied to any computer no matter where it is located you do not pay 'rent' to do so.  The data is not automatically sent to the cloud and no third party has to be paid to keep your data safe.  Your data is stored safely in the QuickCheck display in non-volatile memory.  It can be automatically downloaded to a computer on your own network or server for back up purposes.  And the alarms are initiated by the QuickCheck display and not from some cloud computer. 

We do offer an annual calibration service guaranteed to keep all of your sensors calibrated with NIST traceability.  We also offer a swap out program so that you are never without sensors during the calibration process.

Backing up and printing charts

From a data safety standpoint there is no reason to backup the data. The TV2 data is stored in non-volatile RAM memory. However, if you do want to back the TV2 data to your computer for remote viewing or printing out, it is simple. Use the free TView software to automatically backup your data to a server or to download the logged data at any time.  If the automatic download feature is used, a new file will be created each month for all data logged during the month.

The temperature, humidity and differential pressure data can be printed out as a chart or a numeric listing at any time if a paper copy is needed.
