Calibration Equipment & Standards and Calibration Software
Jan 15, 2020
Customers and people at Fluke often ask me questions about calibration intervals:
How often should a unit be sent back for recalibration?
Are there any “rules” for this?
A few years ago, I wrote an application note on establishing calibration intervals on Fluke products, but there still seems to be some confusion on this issue.
What is a calibration interval?
A calibration interval is the period of time established for a test instrument to be returned for recalibration. We recalibrate...

Technician calibrating humidity sensors using the Fluke 5128A humidity generator / calibrator
Humidity sensors are a crucial component of quality control in a manufacturing environment. Often, they are found in “clean rooms” (not to be confused with operating rooms) where a tightly controlled environment — meaning controlled temperature, humidity, and air purity — is critical to product quality and reduction of environmental hazard risks.
Humidity sensors can pose some...

Technician using the Fluke 3130 calibrator to perform an equipment verification or intermediate check per ISO 17025
Intermediate Checks per ISO 17025 (aka “equipment verifications”) are an often-overlooked, but vitally important part of maintaining accurate measurements for manufacturers. This process can catch errors in your sensors and measurement devices before they become serious problems. An increasing number of companies are starting to catch on to the importance of performing...

The 8270A and 8370A Modular High-Pressure Controllers provide the widest pressure calibration workload coverage in an automated pressure controller. The 8270A and 8370A are often purchased to replace a traditional deadweight tester or pressure comparator, and they most often appeal to experts who want a flexible system with the capability for expansion and automation.
There are several questions frequently asked by calibration experts who are considering an upgrade. This overview will quickly...

Customers often request the most accurate piece of equipment available, but the most accurate product is not always the best solution for their needs. If you are planning to purchase a new pressure controller for production, there are several areas that you should consider before determining which piece of equipment is right for your use case.
When purchasing a pressure controller, it’s important to consider your accuracy and pressure needs, the product’s environment, expected uptime,...

Two of the most common reasons to upgrade to an 8270A or 8370A Modular High-Pressure Controller are the desire to increase throughput efficiency and the need to increase accuracy or pressure range capabilities. Often, metrologists are also looking for scalable technology and instruments that can be automated.
Technology Behind Pressure Coverage
The technology in Fluke Calibration modular pressure calibrators that enables wide pressure coverage is driven by the variety of the pressure...

There are several reasons why someone might upgrade to a modular pressure control system for their existing standards. The most common are: ease of use, flexibility, and the ability to use high-pressure gas.
Fluke Calibration offers the 8270A and 8370A Modular High-Pressure Controllers as modern replacements for hydraulic deadweight testers and comparators. The 8270A and 8370A are automated pneumatic pressure controllers that can be configured with up to five measurement modules at the same...

One of the qualities of Fluke Calibration test and measurement equipment is excellent longevity. With regular care and maintenance, Fluke calibrators can last for many years and become staples of the calibration lab. Moreover, many of our customers pride themselves on their ability to repair older equipment, making Fluke Calibration products assets that provide a return on investment for decades.
When we say a calibrator is “end of life” it can be easy to assume we mean any calibrator that isn...
