Designed for high performance in craft scale stainless steel fermentation tanks, the new Tilt® Pro brings Tilt technology along with massively boosted wireless range to professional craft brewers. At 3x the volume and weight of our original Tilt hydrometer, the Tilt Pro's larger size allows for increased power for longer ranges in stainless. The included AA lithium batteries will last for 1 to 2 years depending on use, similar to the standard Tilt. The extra size and weight comes with an extra bonus: improved specific gravity stability at high krausen so you will see a steadier read-out on your iPhone, Android, or Raspberry Pi. In addition, the boosted range from an improved power amplifier and high-gain antenna showed 2X to 3X range improvement in testing, over the original Tilt. Now you can see your Tilt through thicker heads of foam and heavier stainless steel walls. To top it off users will see an extra decimal of precision available from the sensors and to the read-out. There are now decimal degrees Fahrenheit as well as higher resolution Celsius. Specific gravity now reads out to the 10,000th place (for example 1.0000). You can now see fermentation activity dropping less than a brewer's point per day. Several adjustments we made with the craft beer professional (and serious home brewer) in mind. Specifications Size: 1.7" (43mm) diameter (max) by 5.4" (140mm) tall Weight: 5.4 ounces (153g) Specific Gravity Measurement Range: 0.9900 - 1.1200 Specific Gravity resolution: 0.0001 Temperature Measurement Range: 0°F - 140°F (-17.8°C - 60°C) Note: Installed lithium batteries include a built in PTC (heat activated fuse) that will temporarily cut power if batteries exceed 140°F. Temperature resolution: 0.1°F (0.1°C) Absolute Maximum Temperature Range: -40°F to 185°F (-40°C to 85°C) Battery: User-replaceable, 2x 1.5v AA battery (Li/FeS2), widely sold as "Energizer® AA Ultimate Lithium". Note: Other batteries such as alkaline or heavy-duty batteries are too heavy and will cause the Tilt Pro to sink. Download the free Tilt app at the Apple App Store or Google Play Store.
