Dear Rick Kaestner,

Is monitoring humidity important to you?

There is a better alternative to the old mechanical, maintenance intensive hygrometer.

 How do you Protect a Slugger?

Louisville Slugger has been around since 1884. They supply baseball bats to over 60% of the major league players, having literally dominated the game of baseball since it became a game. During all of those many years they accumulated a lot of baseball memorabilia, letters for the all-time greats, bats that once belonged to the real heavy hitters, their shoes, uniforms, pictures, etc.

When the folks at Louisville Slugger decided to build a museum to display some of the many items, they hired a full time museum director, who installed Two Dimensional Instruments (2di), hygrometers to monitor and document the temperature and humidity at multiple points in the museum.

The Louisville Slugger museum, like all museums, must protect their collection. Everything has to be stored and displayed at precise temperature and humidity levels. They use 2di hygrometers to monitor the indoor conditions. The curators, employees, and even the public can verify that the priceless items of America’s greatest sport are being kept at the optimum conditions.

They choose 2di hygrometers because they are accurate, inexpensive and don’t need to be recalibrated. Traditionally, museums have used thermo-hygrometers with paper charts, pens and human hairs to create a record of the storage environment. While they do an adequate job of measuring and recording temperature/RH they are expensive and need constant maintenance. The 2di hygrometer is an all-electronic instrument that can store and display ten months of temperature/RH history.

 Application Note
 Monitoring Temperature/RH

It is often critical that temperature and humidity be monitored and kept within a fairly narrow range. For example, works of art must be maintained at a constant temperature and RH to prevent deterioration.

Modern HVAC systems do a good job of this generally, but it is still necessary to check these conditions for two reasons. Pockets of humidity or warm air can occur where the air is not circulating properly. Also lending institutions require proof that the indoor environmental conditions are maintained before sending items from their inventory for display.

The ThemaViewer is the ideal instrument for monitoring and documenting the temperature and humidity in museums. It is accurate and automatic, providing continuous monitoring and indicating trends so that any deviation is immediately apparent.

Sincerely,
