Two Dimensional Instruments
The paperless Hygrometer provides constant temperature/humidity monitoring without paper, pens or maintenance. Temperature and humidity is sampled once every 5 seconds and an average is stored in the memory of the display unit every 10 minutes. Over one year of 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 the calibration table built into each sensor. Each Hygrometer has a password-protected three point built-in calibration table so that adjustments can be made during calibration.
Forget about wiring your sensors to the display unit. Just put the wireless sensors in the area where it makes the most sense and mount the display unit on the wall in a central location. The display unit can track up to four different wireless sensors. Each Hygrometer can receive temperature and humidity data from wireless sensors. Range: 100 feet, clear line-of-sight.
The Paperless Hygrometer is used in museums, computer rooms, clean rooms, testing labs, laboratories, etc.. to provide accurate temperature/humidity monitoring. The wireless sensors can be put in display cases, up in the corner of a room or even inside an incubator. The display unit has a metal enclosure so it can be placed in high traffic areas without worrying about possible damage from visitors.
The Hygrometer can be placed in display areas or even in
display cases to monitor the temperature and humidity.
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.
Although there are buttons on the front of the display, visitors
can not get into the password-protected setup menus.
The data can easily be downloaded to a computer where charts or numeric data can be printed out to be sent or even emailed to lending institutions when required.
The hygrometer uses analog sensors to monitor the temperature and humidity to insure 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 insure 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 every adjustments can be made with the built in calibration table.
Placing the Hygrometer in the testing areas insures 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.
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.
