Humidifier With Digital Hygrometer Cello

Stretto Humidification System.

The Stretto Humidifier is an elegant grey PVC container plus two bags of crystals.
The container has a self-adhesive 3M strip, allowing it to be easily attached to the inside of a case.

From personal experience as a musician, I am keenly aware of the necessity of maintaining the optimal humidity for a String Instrument. We must protect our fine Instruments from changes in humidity, be it when travelling, making the trip from home to concert hall, or simply adapting to changes in the weather and season. Until now, there has not been an ideal product available.


We have thoroughly tested the STRETTO. We are convinced that STRETTO and the digital Hydro- / Thermometer accompanying it offer the best protection for any String Instrument.

Due to its compact size, STRETTO fits in to any instrument case and is easy to use. (Violin / Viola: 95 x 65 x 15 mm, Cello 115 x 95 x 15 mm).

Simply soak the STRETTO bag in water for 10 minutes, wipe the bag dry and put it inside the STRETTO plastic container. Now place the entire unit into the instrument's case.
The STRETTO humidifier will keep the humidity inside the case stable between 50% and 60% for approx. 2 weeks.
One bag will last for approx. 3 months of constant use. The bag's lifespan can be increased to approx. 6 months if distilled water is used.

Digital HygroThermometer.
Simultaneously measures humidity and temperature. Features a memory function which records (and displays at the push of a button) the highest temperature and the lowest humidity measured during a given period of time.

Large, easily readable display, can be set to either °C or °F. The self-adhesive strip allows the unit to be attached to the inside of a case.
Easy to use, dimension 78 x 58 x 20 mm, incl. 1.5V battery.
