TESTING HUMIDITY AND TEMPERATURE
AND MOLD PREVENTION


This page is all about preventing mold and mildew in a piano, AND it is about preventing moisture that can rust piano metal parts and damage the cabinet.

If you already have a mold of mildew problems, GO HERE to find ways to eradicate it.

         Programmable alarm visually and audibly warns when
         humidity exceeds a preset Hi or Lo limit. LCD shows
         dew point temperature and Min./Max. with reset
         function. 0.1 Degree F. resolution. Temperature probe
         extends on 18" cable. Temp. accuracy: Plus or
         Minus 1.8 Degree F. RH accuracy: Plus or Minus
         4%. Includes stand, wall mount brackets, and
         batteries.

         Relative Humidity Range 10 To 99%, Temp Range
         14 To 140 F, Temp Range -10 To 60 C, Humidity

         Bracket, Battery and Instructions

         This meter is ideal to use with a Piano Cover, like our
         Vinyl Cover, and put the probe under the cover and
         the monitor outside where it can tell you exactly what
         is happening inside the piano. When someone leaves the door open on
         a humid day, or a very dry winter day, and the room temperature
         changes suddenly, the inside of the piano may not change a lot. If the
         alarm does not go off, you don't need to deal with humidity control.

                    Part Number- GR5PE71             Price- $ 98.00

HUMIDITY INDICATOR CARDS

 

This neat little card is the easy way to learn what the humidity is in your piano. The card is like the cards you have seen for years which turn blue or pink according to the humidity.

The percent of relative humidity is on the card, and you will figure this by the spot which is lavender between blue and pink. This card is used in the silica gel trade in another application, so you will ignore the instruction to "change the deccicant."

If you use this card, by placing it in the piano cabinet, you will know if your heat bar is over drying the piano, and you will be able to see if the humidity gets above the level you desire.

     Part Number-- Crd-01                         Price- $ 2.00 ea




 

MOLD AWAY

Protect Your upright piano against potentially dangerous mold and fungus with Mold Away™. Simply remove the pack from its pouch and place it in the closet, kitchen, bathroom, basement or garage. The all-natural ingredients (clay and lime) absorb excess moisture, keeping humidity below 30 percent in confined areas. Indicator dots turn pink to let you know when it's time to dispose of the pack. The materials stay in solid form so there's no danger of leakage.

This product will be of use ONLY in upright pianos. Ideal also for any damp situation in the home. Keep one in your gun safe!

                                       Part Number-- MA-02                         Price- $ 25.00 for a three pack

 

 

HEAT BARS AND HUMIDITY CONTROL

ALTERNATIVE TO PIANO MOUNTED DEVICES:

Never use a heat bar alone on a piano. It is too easy to forget it and dry the piano out too far in the winter when humidity is low.

Buy a room humidifier and dehumidifier at WalMart or Sears.  Be sure they are big enough to run for a few days without having to be filled frequently. Position the appliances in the room so that they are not too far from the piano, but not close enough for the humidifier to blow unevaporated water vapor onto the piano. Humidity is adsorbed into a room faster than heat because air acts as a sponge to water moisture. Try to keep the humidity in the room between 40 and 55%.

In the Southwest you may want to consider summer cooling with a "swamp cooler" rather than air conditioning. The added moisture is desirable during very dry times, and it is more healthy for you than air conditioning. You will still need a dehumidifier for the rainy times, such as the monsoon months in Arizona and along the Pacific coast and the Gulf. In the Dixie and Hawaii you will need a dehumidifier urgently, especially along the Atlantic and Gulf coasts. These areas can badly rust strings and other metal parts inside the piano. In the North Woods, the main consideration is to add humidity in the winter when the home is very dry indoors. If you live in Kansas, just sprinkle corn meal around the house every day and it will absorb the humidity. Don't ever say we never innovate at this site :-)

HUMIDISTAT

A Humidistat senses the humidity in the air and turns your appliances on or off, according to the need and your settings and choices.  It interrupts your appliances and the wall plug.  Humidistats are used in many applications and in many industries. Be sure the humidistat has two AC outlets to plug in both a humidifier and a dehumidifier at the same time. This will allow you to control the humidity all year long. I have had customers use this method of control and were very pleased with the results.

If you wish to add a humidistat to prevent over or under humidifying, I suggest the following:

 

A VERY EXPENSIVE CONTROL, BUT THIS ONE WOULD CONTROL BOTH
THE HEAT BAR AND THE ROOM HUMIDIFIER-- Suggested for institutions:

FOR THOSE WHO WOULD LIKE TO ADD A SYSTEM TO THE DUCT WORKS:

POSSIBLE SOURCE, BUT YOU WILL NEED TO BANG ON THE DOOR:

AGAIN, LOOKS LIKE A GOOD SOURCE, AND WOULD CONTROL BOTH THE
HEAT BAR AND ROOM HUMIDIFIER, BUT YOU WILL HAVE TO BANG ON THE DOOR:

THIS MAY BE THE BEST DEAL.  This page contains both humidity meters and
Humidistats, and they look like they would fit your need:
