The intra thoracic pressure can be measured in the standing horse and also in the working horse. The three different systems can all measure in the standing horse but only the Equivent 200 and 300 can measure during workout. The 200 sends the pressure to a smartphone or tablet and the 300 to a PC or laptop. Saving the signal for later use is easier with the 300. The pressure range is + 10 to – 30 cm of water.
The Equivent 100 has no internal battery, de 200 and 300 have a Li-Ion pack. This has to be charged with the supplied charger. Overcharging is not possible. If not in use, the battery will drain in 2 or 3 month. So charge it before use. The blue charging led will shine brightly when charging and will dim when fully charged (after app 2 hours).
The devices are not submersible in liquids. The pressure port must be kept free of liquids and dirt. Cleaning is possible with a moist cloth. All systems have 2 years of warranty. Evident external damage to the system or opening of the system will void the warranty.
