How to Make sure the thread is M8?

To ensure accuracy, please remove the factory gauge and measure the thread length or diameter? Generally, the thread is a cube shape, with the diameter and length being roughly the same. For example, an M8x1 thread has a length of about 8mm and a diameter of about 8mm, while a 1/8 BSPP thread has a length of about 10mm and a diameter of about 10mm.

Product Overview: 

The 25 Std Sekhmet digital pressure gauge is the smallest, largest-screen, highest-accuracy, fastest-reading, and most user-friendly high-pressure gauge in the world.

It features a large visible range, seamless one-piece design, elegant touch button operation, and a super large rechargeable battery that can last up to 3 months on a single charge. Easily mounted on air rifles, it allows magnetic charging without needing to release pressure for battery replacement.

Key Features:

• Thread Specification: M8 thread, specifically designed for  Air Venturi Avenger, AEA, early versions of FX DRS, and Western Airgun Sidewinder.

It allows you to observe the minute changes in the pressure chamber after each shot, ensuring that the pressure returns precisely to the set value. This helps maintain consistent air usage for each shot, significantly improving shooting accuracy.

Q. 25std Battery Icon Misunderstanding:

A: Some users mistake the battery icon for a charging progress bar.

The icon is merely an indicator to differentiate it from the pressure bar display page. The actual battery level is shown as numbers next to the battery icon, displayed in five levels: Lo / 5 / 20 / 60 / 100.
