Silicone Pad Specifications

• The included silicone pad measures approximately 13 cm × 8.8 cm × 0.2 cm.

• The pad helps stabilize the scale and protect surfaces from heat or scratches.

Transparent Cover & Surface Protection

The transparent top cover of the Ultra Scale is made from high-temperature-resistant clear PC plastic with enhanced scratch resistance.

To improve durability:

• The surface is UV-hardened

• A protective film is pre-applied at the factory

The protective film covers most of the top surface. Due to the curved edges of the scale, full edge coverage may not be possible.

For additional protection, the included silicone pad can be used during daily operation.

Bluetooth Specifications

The Ultra Scale uses low-power 2.4 GHz Bluetooth (version 5.0).
It shares the same Bluetooth technology foundation as the Themis Mini Scale.

This means that if a coffee machine supports the Themis Mini, it will also support the Themis Ultra.

Bluetooth device names:

• Themis Mini: BOOKOO_SC xxxx

• Themis Ultra: BOOKOO_SC U XXXX

Color Options

The Themis Ultra Scale is currently available in black and white only.

There are no additional color options at this time.

Temperature Stability & Compensation

The Ultra Scale is equipped with a temperature compensation algorithm and has undergone physical temperature testing to ensure stable performance.

In high-temperature scenarios, such as placing a preheated glass carafe on the scale, external heat conduction may temporarily affect weight readings.

Therefore, using a heat-insulating pad (for example, the included silicone pad) is an effective way to reduce this effect.
