Protect your Cleanroom

The TV2 QuickCheck monitor uses state-of-the-art differential pressure and temperature/humidity sensors 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. The TV2 cleanroom monitor also logs differential pressure, temperature and RH 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 specs 24/7.  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.  Mount it at the cleanroom entrance so it gives an instant check to each employee before he enters. The differential pressure sensor is customized for pressure between -1"wc and 1"wc and is accurate to ±0.007"wc.

Monitor, Alarm, Log and Chart

Clean RoomThe TV2 Cleanroom monitor continually tracks temperature, relative humidity and differential pressure.  Each variable is not only displayed so you know what the current conditions are but each is also logged.  A complete history of each condition can be viewed on the screen, downloaded to a PC, or printed out as a chart. 

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

The optional alert software initiates an email or text alert anytime any of the sensors go into alert mode so that the user has plenty of warning if that condition has become unsafe.  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 logged data.  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 history 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.

Trace Mode

ManufacturingIn addition to seeing the chart for each sensor on the display you can use the trace mode to scroll through each sensors logged data.  You can move back and forth on the chart to examine each individual reading, showing the day and time it was taken.  This makes it easy to pinpoint a high point and see when it occurred, how long it lasted and whether it was a quick spike or a slow ramp up.


Sensors

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.

        Relative Humidity sensor 0% to 100% (±3.0%)

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. 

Backing up and printing charts

From a data safety standpoint there is no reason to backup the data.  However if you do want to back it up to your computer for remote viewing or printing out, it is simple. Use the TView software (free) to automatically backup your data to a computer 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.
