Continuous Monitoring of Temperature and Humidity

The paperless  TV2 Thermo-Hygrometer provides constant temperature/humidity monitoring without paper, pens.  Temperature and humidity is sampled once every few seconds and an average is stored in non-volatile memory every 10 minutes.  Nine months of temperature and humidity history is stored and displayed.  

The problems inherent in older mechanical hygrometers are eliminated since there are no moving parts. The sensors stay in calibration for long periods of time and are easily recalibrated with a three-point calibration table built into each sensor.   Often the old type of mechanical hygrometer would be 'flicked' by a visitor causing the instrument to no only stop working but also to need recalibration.  Visitors can not upset the recording mechanism of this paperless Hygrometer because it is all digital.  And the sensor pods are enclosed in a small plastic box to protect them from inquisitive visitors.

Wireless Sensors

Forget about running wires to the sensors.  Just position the wireless sensors in the areas you want to monitor or alarm and mount the display unit on the wall in a central location.  The range is: over 60 feet, clear line-of-sight.

Museums, Clean Rooms, Warehouses, Testing Labs, etc...

The Paperless Hygrometer is used in museums, art galleries, computer rooms, clean rooms, testing labs, laboratories, etc.. to provide accurate temperature/humidity monitoring.

Hygrometer

The temperature and humidity data can be downloaded to a computer either on demand or continuously so charts or numeric data can be printed out or saved to files to be sent or even emailed to lending institutions when required.

The hygrometer uses analog sensors to monitor the temperature and humidity to ensure that the readings it takes are accurate.  But, the analog readings are converted to a 24-bit digital number before being transmitted to the display unit, to ensure the complete accuracy of the measurement.

The sensors do not need to be recalibrated frequently.  If you have been using a sling psychrometer to recalibrate the old drum type hygrometers you can throw it away.   If the sensors do need to be recalibrated adjustments can be made to the built in calibration table.

Testing Laboratories

Placing the Hygrometer in the testing areas ensures that you will have a complete record of temperature and humidity conditions during testing.  A chart of conditions during testing can be printed out and included with the test results also.

Warehouses

If you are storing inventory that is temperature and/or humidity sensitive the Hygrometer is the perfect instrument for protecting that inventory.  High and low alarms can be set for temperature and humidity to alert you if conditions every become unsafe.  If you are storing goods for a customer you can print out or email a chart of conditions in the warehouse each month for your records.

Copy the Temperature and Humidity log to a Computer

The TV2 Hygrometer downloads to your computer through the USB power cord automatically if you power the display with a computer.  It copies the temperature and humidity every few minutes so you always have a backup copy of your data on your computer.  Charts can be viewed on the computer screen and printed for any period of time.
