Museums, Clean Rooms, Warehouses, Testing Labs, etc…
The Paperless Hygrometer is used in:
- Art galleries;
- Computer rooms;
- Clean rooms;
- Testing labs;
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 may be printed out or saved to files for lending institutions or regulatory agencies 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.
Each environmental variable can be set with its own high and low point and delay time. Any variable which moves out of its set ‘safe’ range will turn red on the display and once the delay time is exceeded a local alarm will sound and text/email messages are sent. A phone call alert is also available.
The TV2 Hygrometer downloads to your computer over your Local Area Network automatically with the free TView PC interface software. 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. All logged data is encrypted to prevent anyone changing the data.

Q. How accurate is the temperature sensor?
A. Our TV2 temperature sensor is accurate to ±0.3°C.
Q. How accurate is the humidity sensor?
A. Our humidity sensors is accurate to ±3.0%.
Q. Do I need both a humidity and a temperature sensor?
A. No, the temperature sensor and humidity sensor are built into one module measuring 2″ x 2″ x 1″.
Q. Can I print out a log of temperature and humidity?
A. Yes, the logged data can be downloaded to a PC at any time and a color chart of conditions can be printed. In addition to printing out a chart of logged temperature and humidity the data can also be exported into an Excel file.
Q. Do I need technical help to install the TV2?
A. Not usually. If help is needed we can supply it via telephone, which is almost always sufficient. If you have a very large computer system your are integrating the TV2 into, you might need some help from your IT department.
Q. Can I see the current temperature/humidity on my phone or from my home computer?
A. Yes if you use port forwarding. You might need some technical assistance from your computer guys to do this.
Q. Does the TV2 monitor meet JCAHO, CAP, FDA requirements?
A. Yes. It meets and exceeds all requirements for monitoring temperature and humidity.
Q. How far away can the sensors be mounted from the TV2 monitor?
A. The wireless sensors have a clear line-of-sight range of ~ 100 feet. Metal racks and walls between the sensors and monitor will decrease the range.
Q. How can I get the sensors further away from the monitor?
A. Our wired sensors which can be extended to hundreds of feet. We have fifty foot extension wires which an be daisy-chained together if needed. Sensors can be positioned up to 300 feet away from the modules.
Q. What is the difference in accuracy between wired and wireless sensors?
A. The accuracy is identical.
Q. Do I mount the monitor in the office even though the sensors are in the warehouse?
A. It depends. If you are using wireless sensors the range will cut down if the signals have to go through walls. However if you place the monitor and sensors in the warehouse and plug the monitor into a wired Ethernet socket you can view the data on any computer which is part of the same LAN.
Q. Do the sensors need to be plugged into wall power?
A. No. Each sensors is powered by a 9 volt DC battery which has a life of about a year?
Q. How often is the display updated?
A. Every eleven to twenty seconds.
Q. How often is data logged?
A. This can be set to any interval between once a minute to once a day. Each sensor can have its own data-logging interval. The default interval is every 10 minutes.
Q. How safe is the logged temperature/humidity data?
A. Logged data is stored in non-volatile memory in the monitor. It can also be automatically backed up to a computer.

Monitor up to four different areas with wireless sensors (±0.5°F, ±3.0%). Position the password-protected monitor in high traffic areas with complete confidence, so everyone can see the temperature and humidity. A two stage alarm alerts everyone to a potentially unsafe condition. Generate data charts any time, which can be printed or emailed to establish a history of safe storage.
