TV2 Digital Hygrometer

No Paper or Pens!

The paperless  TV2 Thermo-Hygrometer provides constant temperature and relative humidity monitoring without paper or pens.  Temperature and humidity is sampled once every few seconds and an average is stored in non-volatile memory every few minutes, depending on the user settings.  Over a year of temperature and humidity history is stored and displayed on the Quick-Check monitor for each of its four sensors.

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 re-calibrated with a three-point calibration table built into each sensor.   Often the old type of mechanical hygrometer would be ‘flicked’ by a someone causing the instrument to, no only stop working, but also to need re-calibration.  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. There are no worries about unauthorized personnel messing up the settings as everything is password protected.  

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.

The temperature and humidity data logged by the monitor can be downloaded to a computer either on demand or continuously so charts or numeric data can be printed out or saved to files for 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 re-calibrated frequently.  If you have been using a sling psychrometer to re-calibrate the old drum type hygrometers you can throw it away.   If the sensors do need to be re-calibrated, 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.


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. The TV2 hygrometer can send phone, email or text alerts if any monitored condition becomes 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

Each TV2 Hygrometer comes with either a wired Ethernet connection or WiFi connection so it can be accessed by a computer to automatically download the logged data every few minutes.  The copied data is added to files stored in your network so it is instantly accessible by anyone on the same network.  Real time or historical data charts can be viewed on the computer screen and printed for any period of time.
