# PLAATO Pro Fermentation Data

## A Guide to Understanding and Using Your Data

PLAATO Pro uses vibrating fork density technology to measure the density of your brew. The device’s tines vibrate at a frequency that changes depending on the liquid’s density:

- **Higher density → Lower vibration frequency**
- **Lower density → Higher vibration frequency**

 From this vibration frequency, PLAATO Pro calculates:

- **Specific Gravity (SG)**
- **Degrees Plato (°P)**

 The device also measures the **temperature** of your brew.

💡 PLAATO Pro takes measurements hourly and sends the data directly to your app.

**Below is a guide to understanding each data unit 👇🏼**

### **Temperature**

Fermentation temperature significantly impacts the final taste, clarity, strength, and aroma of your brew. Monitoring temperature is therefore essential.

In the PLAATO Pro App, temperature is displayed in °F or °C.

To change units:  
Account → Preferences → Units

### **Density (Specific Gravity / Plato)**

Density, also called **Specific Gravity (SG)** or **Degrees Plato (°P)** measures how dense your brew is compared to water. It indicates the level of alcohol conversion in your brew every time the Plaato Pro does a reading.

### **Frequency (Hz)**

The tines inside your PLAATO Pro vibrate proportionally to the density of your brew.

- High vibration frequency → Low density
- Low vibration frequency → High density

In your app you are able to follow density levels closely to ensure the brew is fermenting by recipe standard.

💡 Frequency is measured in **Hertz (Hz)**.

### **Battery Level & WiFi Strength**

In the PLAATO Pro App, you can view Battery Level and WiFi Strength graphs under each device’s **Device Details** section.

This will help you avoid situations where you run out of battery life 🔋, and to keep track of WiFi strength 📶 when brewing.

### **Cloud & Battery Status**

The battery level and cloud connection status of each Plaato Pro device is displayed like below👇🏼

This allows you to quickly confirm that your device is powered and actively syncing data.👍
