TILT® PRO Wireless Hydrometer and Thermometer


Tax included

Available Now!

Designed for high performance production scale stainless steel fermentation tanks, the NEW! Tilt® Pro brings Tilt technology to professional craft brewers.

At 3 X the volume and weight of the original Tilt hydrometer, the Tilt Pro's larger size allows us to more than double the battery life with preinstalled Energizer® AA lithium batteries that will keep it powered for 3 to 5 years depending on use. So much time you may forget your Tilt actually runs on a battery! 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, we have boosted range with a high-gain antenna that in testing increased range by 20% vs. our original Tilt. Now you can see your Tilt through thicker heads of foam and heavier stainless steel walls. To top it off TILT has included the extra decimal of precision available from the sensors and to the read-out so 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. In all TILT has made several adjustments they believe the craft beer professional (and serious home brewer) is sure to appreciate.

TILT goal is to help brewers brew better beer. The Tilt hydrometer allows you to check the specific gravity and temperature of your beer while it's fermenting, without ever having to open your fermenter or pour out any of your precious brew. This makes brewing more consistent and easy to track. 

Here are some of the new features of the Tilt:

  • Range: Better reception and range. With the increased transmission power your Tilt will send data through larger, thicker-walled fermenters.
  • Precision: Upgraded sensors. With an improved temperature sensor and accelerometer your Tilt will operate with more precision.  
  • Efficiency: We've reduced power consumption so more brews, less battery.
  • New Look: Newly designed custom circuit board and harness.

If using multiple Tilt hydrometers for different batches of fermenting beer you must use a different color for each batch. The app will not read multiple hydrometers of the same color.

Each Tilt Pro comes calibrated and ready to go with a pre-installed Energizer® AA Ultimate Lithium batteries that lasts 3-5 years depending on usage. Just download the free app, sanitize your Tilt, drop in your fermenter, and start taking readings with your phone, tablet, or Tilt Pi. 

Download the free Tilt app at the Apple App Store or Google Play Store or get the free Tilt Pi download. 


Frequently Asked Questions

Q. Why am I not getting regular updates on my Google Sheet?

Q. Is the Tilt compatible with Android phones and tablets?

A. Yes, in general most Android phone or tablet with Bluetooth 4.0 and Android OS version 4.3+. See our list here: http://tilthydrometer.com/pages/compatible-android-device-list

Q. How often does the Tilt take measurement readings?

A. The Tilt will send updated measurement readings for temperature and specific gravity to your iOS or Android device every 5 seconds.

Q. How do I turn off the Tilt when I'm not using it?

A. The Tilt will go into sleep mode when you're not brewing to save battery life. Simply stand the Tilt up or lay it on its side and it will shut off automatically.

Q. How do I turn on the Tilt?

A. Simply drop the Tilt in your fermenting brew and the device will turn on and start taking readings automatically within a minute, typically 5-15 seconds. Tilt will stay on within an SG range of 0.990 - 1.200.

Q. How long will my battery last?

A. The lithium CR123A battery will last 3 months for our first generation models (blue-green circuit board) or 12 months for our second generation and later models (black circuit board). The second generation model will last 24 months in sleep mode.

Q. How accurate is the Tilt? 

A. The specific gravity is accurate +/- 0.002 within the Tilt's range of 0.990 to 1.120. The thermometer is accurate +/- 1°F (+/- 0.5°C).

Q. How is the Tilt affected by foam?  

A. There is no noticeable interference from foam. Foam plays a minimal role since it is significantly less dense than the beer and 95% of the device is submerged in the beer. 

Q. How do bubbles from CO2 affect the Tilt?

A. We recommend putting the Tilt in your beer prior to pitching yeast, this will ensure any bubbles will not affect initial readings. Bubbles from dissolved CO2 may cause higher than expected readings for a short time if placed in an active fermenting brew. However, this can be sped up if washed with alcohol (i.e. Everclear). 

Q. How precise is the Tilt?

A. The Tilt is as precise as a standard hydrometer. SG readings are in 0.001 increments and temperature readings are in 1°F (0.56°C) increments

Q. How does vigorous fermentation affect the Tilt?

A. You do see a lot of turbulence at peak moments of fermentation, however since data is being collected every few seconds the ability to get a smooth moving average allows for a highly accurate readings. That said, we've come to enjoy reading the non-averaged data because it also tells you how active the fermentation is. In some cases we'll chill the fermentor a little more to prevent blow off and overflow of beer. 

Q. Will I be able to chart the data from the Tilt?

A. Yes. You will be able to log data of your beer's fermentation progress (specific gravity and temperature) to the cloud for sharing, graphing, and archiving. See our apps section on how to set up Google Sheet logging for your Tilt.

Q. Does the SG reported by the Tilt compensate for the current temperature automatically?

A. Due to the polycarbonate housing of the the Tilt, no correction is needed from approximately 38°F to 98°F. Temperatures above 98°F result in an decrease of SG of about 1 point per 10°F. i.e. water at around 160°F will read 0.994.

Q. How do I sanitize and/or clean my Tilt?

A. The polycarbonate container and washers/o-rings are safe with StarSan, which is our recommended sanitizer. Use warm water and dish soap for cleaning. Do not use a scrubber or soak in PBW for more than a few hours, this can cause hairline cracks in the polycarbonate.

Q How often does the Tilt post data to the cloud/Google Sheets?  

A. The iOS/Android app will update gravity and temperature data every 15 minutes to Google Sheets. The Tilt Pi can update data every 5 minutes to 60 minutes depending on setting selected.

Q. Does the Tilt work with a Raspberry Pi?  

A. Yes! You can get a free SD card image download to our Tilt Pi here

Q. Can I develop my own app for the Tilt. Do you have any technical information available to do this on different systems?

A. Yes. The Tilt uses iBeacon to broadcast data. See the following link for detail on the data format: https://kvurd.com/blog/tilt-hydrometer-ibeacon-data-format/

Q.  My Tilt is displaying numbers that don't look anywhere near to accurate. Is it broken?

A. Please make sure that you've removed the Tilt from its plastic shipping tube prior to using it.

Q. Can I use the Tilt under pressure?

A. Yes. The Tilt works great under pressure. Here's a blog post on that subject. https://tilthydrometer.com/blogs/news/controlling-fermentation-rate-with-pressure

Q. How do I know if my battery is still good (battery indicator)?

A. When waking your Tilt from a standing or laying down position you will see an LED on the circuit board blink green, indicating the battery is good. If you can't see the LED or it is very dim, you'll want to swap out your battery. It is recommended to double check that the LED did not flash by putting the Tilt to sleep again (letting it stand vertically or lay horizontally for 30 seconds or until you see the LED blink blue) and waking it up again in a glass of water. Changing the battery will require recalibration so it is best to be sure the battery is really dead before changing it.

Q. Time zone appears to be GMT. How do I change the time zone on the Tilt Pi?

A. After setting up a Tilt Pi using the SD card image download, you can access the Tilt Pi dashboard with a phone or computer connected on the same WiFi network by going to http://tiltpi.local:1880/ui (for Mac and iOS devices) or http://x.x.x.x:1880/ui where x.x.x.x is the local IP address of your Raspberry Pi (use your WiFi router settings page to determine this address by going to your connected device list and looking for "tiltpi" device). Once in the dashboard, go to the menu->system->Time Zone to select the correct time zone. Restart the Raspberry Pi and the system time zone should then be updated.
