Gen-2 255 STD Sekhmet Digital Pressure Gauge 300 bar (1/8 BSPP thread)

New updated, 25.5mm in diameter!

Product Overview:

The 255 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: 1/8 BSPP thread, specifically designed for FX (except DRS early edition), Daystate, BRK, Airgun Technology, Kalibrgun, Edgun, RTI...
• The 255 STD model: Exclusively displays the current pressure without any calculation functions, making it highly recommended for use with regulators. 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.
• 5-level battery indicator, low battery flashing, and charging reminder.

Specifications:

• Pressure Range:15 to 300 bar (217 to 4351 psi)
• Accuracy Class: 0.25, with a maximum full-scale error of ±0.75 bar at 300 bar
• Display: 6.3‘inch large non-illuminated LCD screen
• Diameter: 25.5mm;  Height 18.5mm(thread exclusive); Weight: 25g
• Pressure Units:** bar only (no psi switch)

Package Includes:

• Gen-2 255 std Gauge with  1/8 BSPP threaded
• User manual
• Magnetic USB charging cable
• Sealing kit (includes O-ring, X-ring, PTFE gasket)

   

  1- Installation Requirements

  The internal structure of digital pressure gauges is compact. Using a wrench for installation is strictly prohibited, and over-tightening by hand is also not allowed:

  • Excessive pressure may cause case deformation (which may lead to panel detachment) or squeeze the ceramic sensor at the bottom (resulting in inaccurate pressure readings).

  • Correct Operation: Only tighten by hand, and stop immediately when you feel resistance from the seal.

  2-Maintenance Key Points

  For models with built-in lithium batteries, special attention must be paid to battery maintenance (as you have previously encountered battery failure due to long-term idleness, we hereby emphasize this reminder):

  • If the product is used frequently in daily life, no additional charging attention is required.

  • If the product is idle, please fully charge it at least once every 3 months (charging for more than 1 hour each time) to avoid battery electrolyte drying, which may cause power attenuation, inability to charge, and affect service life.
