Certified Thread Gauges You Can Trust | Northern Gage

  Calibration Intervals: The Key to Keeping Your Precision Tools on Point Precision tools and thread gauges —like Northern Gauge’s NG-ThreadMaster and NG-NPT series —are engineered for uncompromising accuracy. But even the toughest, most reliable gauge will eventually drift out of tolerance if it isn’t recalibrated on time. That’s where calibration intervals come in. Tracking and maintaining them is the difference between consistent success and costly mistakes. Here’s why they matter, how they protect your bottom line, and how Northern Gauge helps you get it right—every time. 1. What Are Calibration Intervals and Why Track Them? A calibration interval is the set period between tool calibrations—often 3, 6, or 12 months—determined by usage frequency , environmental conditions , and industry standards . Why they matter: Over time, even precision instruments experience small shifts due to wear, temperature changes, and heavy use . Example: An NG-500 Digital Gauge used ...

  Timing Is Everything: Why Tracking Calibration Intervals for Precision Tools Matters Precision tools and thread gauges —like Northern Gauge’s NG-ThreadMaster and NG-NPT series —are built for accuracy you can count on. But even the most durable tools don’t hold their precision forever. Calibration intervals —the set time between recalibrations—are the safeguard that keeps your tools performing exactly as intended. Miss that timing, and the risks are serious: errors, production delays, compliance failures, and costly rework. Let’s break down why calibration timing matters and how Northern Gauge helps you stay ahead of the curve. 1. What Are Calibration Intervals and Why Track Them? Definition: A calibration interval is the time period between calibrations—commonly 6 months to 1 year—set to ensure a tool stays within its specified accuracy. Why It Matters: Tools naturally drift over time due to wear, temperature changes, and usage intensity . Tracking calibration interv...

  SO/IEC 17025 Uncovered: The Gold Standard for Calibration and Testing When it comes to calibration , not all labs are created equal. In industries where precision drives progress , the difference between a pass and a costly rework can come down to the lab you choose. ISO/IEC 17025 is the international benchmark that separates the best from the rest, ensuring tools like Northern Gauge’s NG-ThreadMaster and NG-NPT gauges perform flawlessly. So, what makes this standard so important—and why should it matter to you? Let’s break it down. 1. What Is ISO/IEC 17025? Definition: ISO/IEC 17025 is the global standard for calibration and testing laboratories , developed by the International Organization for Standardization (ISO) and the International Electrotechnical Commission (IEC) . Last updated in 2017, it defines the requirements for competence, impartiality, and consistent operations in lab environments. Scope: It applies to labs performing calibration (like adjusting gau...

  Calibration is the heartbeat of precision. In industries from aerospace to oil and gas, every accurate measurement depends on strict, well-defined calibration standards . These standards ensure that tools like Northern Gauge’s NG-ThreadMaster and NG-500 series deliver consistent, trustworthy results—no matter where they’re used. But what exactly are calibration standards, why do they matter, and how do they protect your operations? Let’s break it down. 1. What Are Calibration Standards? Definition: Calibration standards are internationally recognized benchmarks —such as ISO, NIST, and ASME —that define how tools should be tested and adjusted against a known reference. Purpose: They eliminate guesswork. A thread gauge calibrated in Canada should match one in Japan with identical precision—vital for global industries. Key Players: NIST (National Institute of Standards and Technology): U.S.-based authority providing traceable references for calibration labs worldwide...

 Threaded components—whether bolts, nuts, or pipes—are the unsung heroes of countless industrial applications. But here’s the question: how do you ensure those threads meet exact specifications? The answer lies in two simple yet powerful tools: go and no-go thread gauges . At Northern Gauge , our precision-engineered gauges, such as the NG-ThreadMaster series , help manufacturers, oilfield operators, and machinists verify thread quality with speed and confidence. Let’s break down what these gauges are, how they work, and why they’re essential for delivering flawless threads. 1. What Are Go and No-Go Thread Gauges? Go Gauges These test the minimum acceptable size of a thread. If the go gauge fits smoothly—meaning it screws in without force—the thread meets the lower tolerance limit. Think of it as the “pass” signal for functionality. No-Go Gauges These test the maximum allowable size . If the no-go gauge fits or screws in easily, the thread is oversized and fails. This ...

Precision is the foundation of quality manufacturing. In sectors like oil & gas, aerospace, automotive, and heavy engineering, every measurement counts. At Northern Gauge , we know that even the most advanced thread gauges, API gauges, and precision measuring tools can drift over time due to wear and tear. Without regular calibration, that drift can lead to costly production errors, rework, downtime, and even safety hazards. The solution? Regular intervaled calibration through a trusted calibration lab ensures your tools deliver consistent, reliable results—protecting both your productivity and compliance. 1. What Are Intervaled Calibrations and Why Use a Lab? Definition: Intervaled calibration means checking and adjusting your gauges and measuring instruments at fixed intervals—such as every 6 or 12 months—to maintain compliance with standards and ensure measurement accuracy. Why choose a lab? Calibration labs use NIST-traceable standards and maintain controlled envir...
