DeFelsko PosiTector SPG1 Surface Profile Gage

DeFelsko PosiTector SPG1 Surface Profile Gage

In the surface preparation workflow prior to coating, inspecting the surface profile after blasting with sand or abrasive grit is a mandatory step to ensure perfect paint adhesion. The DeFelsko PosiTector SPG1 surface profile gage is a next-generation digital mechanical instrument featuring high durability and rapid measuring capabilities. It stands as an exceptionally cost-effective and efficient solution for contractors, machine shops, and QC teams who require a precise profile measurement device with a reasonable investment cost.

Overview of DeFelsko PosiTector SPG1

The PosiTector SPG1 is researched and manufactured entirely in the USA by DeFelsko – the world’s leading brand in coating thickness and surface measurement instruments. The equipment kit includes:

• PosiTector Standard Gage Body: Features a sharp color display screen with a minimalist interface, focusing on rapidly displaying basic statistical parameters, making it highly effortless to operate.
• Specialized SPG Probe: Utilizes a 60-degree pointed tungsten carbide/artificial diamond stylus, specifically engineered to measure the peak-to-valley height of surface profiles after abrasive grit blasting or mechanical cleaning.

The instrument fully complies with stringent international standards such as ASTM D4417-B, AS 3894.5-C, U.S. Navy NSI 009-32, SANS 5772…

Key Features of DeFelsko PosiTector SPG1

💡 Ultra-Durable Diamond Stylus – Rapid Measuring Operations

The probe of the PosiTector SPG1 features a premium pointed diamond stylus that provides maximum wear resistance after thousands of scans on hard steel surfaces. The device yields peak-to-valley roughness results near-instantaneously (in less than 1 second), helping technicians accelerate inspection timelines at the job site.

💡 User-Friendly Standard Gage Body with Intuitive Display

Unlike the complex Advanced tier, the Standard version of the SPG1 aims for stream-lined efficiency:

• Features a sharp color screen with an auto-rotating display functionality, making it easy to read measurements from any angle.
• Built-in data logging memory stores up to 1,000 readings – completely sufficient for a full day of field acceptance auditing.
• Continuously updates and displays core statistical parameters directly on the screen, including: Maximum (Max), Minimum (Min), Average, and Standard Deviation.

💡 Industry-Standard Design with High Impact Resistance

The gage body is robustly engineered with a shock-absorbing, scratch-resistant rubber holster. It conforms to the IP65 weatherproofing standard, making it highly resistant to water and dust entry, ensuring stable and durable performance in harsh factory floors, offshore rigs, or windy and sunny construction environments.

💡 Effortless Computer Connectivity and Data Exporting

The PosiTector SPG1 comes equipped with a built-in USB port. Technicians can seamlessly connect the instrument to a computer to transfer data via the manufacturer’s free PosiSoft software, supporting professional QC data archiving or report printing for project investors.

Practical Applications of DeFelsko PosiTector SPG1

Thanks to its high cost-efficiency, fast measuring speeds, and absolute measurement reliability, the PosiTector SPG1 is widely implemented in:

• Steel Structure Surface Preparation: Verifying the surface profile of structural steel frames, chemical storage tanks, and oil and gas pipelines after sandblasting and prior to anti-corrosive priming.
• Shipbuilding & Marine Vessel Repair Industry: Evaluating ship hull surface preparation quality, ensuring maximum bonding for expensive anti-fouling coating systems.
• Machine Shops & Abrasive Blasting Facilities: Conducting rapid measurements and quality audits on the surface profile of machinery parts and mechanical components after grit cleaning.
• Floor Coating Installation & Auditing: Measuring surface profile heights on concrete floors or industrial steel floors to optimize Epoxy primer layer adhesion.
