Preg-Tone

The patented PREG-TONE uses high frequency sound waves called ultrasound to detect amniotic fluid present during pregnancy. When this fluid is detected, the instrument produces a loud continuous tone. When used on an animal which is not pregnant, the instrument produces an intermittent recurring tone. The intermittent tone also indicates that good skin contact is being made.

100% accuracy between 30 and 45 days depending on the animal type.

The PREG-TONE has been tested against other ultrasound instruments by leading universities throughout the world. Their studies show the PREG-TONE as the superior instrument, in both accuracy and ease of use.

Swine: Testing may begin as early as 18 days (large litters, 11-12 piglets, will show positive at this stage), and open sows can be diagnosed as early as 30 days. Normal testing time in sows and gilts is 30-73 days.

Uses only loud, easy to hear tones.

During testing, no lights are used, no buttons are pushed, thus attention is not diverted from the animal. A short, intermittent tone indicates good contact, while a loud, continuous tone indicates pregnancy. Since the PREG-TONE uses only loud, easy to hear tones to indicate both pregnancy and non-pregnancy, it can be clipped on the belt or kept in a pocket.

The PREG-TONE does not need to be seen or held during testing.

Rechargeable NiMH batteries.  Low battery indication.
Specially chosen by Renco Corporation to assure long life, the battery pack will last for years, and give many hours of testing on one charge. The PREG-TONE automatically turns itself off when the battery needs recharging, protecting the user against erroneous readings due to insufficient power. The battery is environmentally friendly.
