Choosing the Right Test Indicator: Your Essential Buying Guide
Test indicators are helpful tools for anyone who needs to measure tiny changes in position. They are often used in workshops and by people who like to build or fix things. This guide will help you pick the best test indicator for your needs.
Key Features to Look For
When you buy a test indicator, check for these important features:
- Reading Accuracy: This tells you how precise the indicator is. A higher accuracy means you can measure smaller movements. Look for indicators with small measurement increments, like 0.01mm or 0.0005 inches.
- Dial Size and Readability: A larger dial with clear numbers and markings makes it easier to read the measurements. Some dials have a sweep hand that shows many rotations, and a small counter hand that shows how many full rotations have happened.
- Contact Point (Stylus) Type: The contact point is the part that touches the surface you are measuring. They can be pointed, rounded, or ball-shaped. A pointed stylus is good for small features, while a rounded or ball stylus is better for smooth surfaces. Some indicators let you swap out different contact points.
- Jeweled Bearings: These small, hard stones help the indicator’s moving parts move smoothly and last longer. Indicators with jeweled bearings are usually higher quality.
- Magnetic Base (Optional): Some test indicators come with a magnetic base. This lets you easily attach the indicator to metal surfaces for stable measurements.
Important Materials
The materials used in a test indicator affect its durability and how well it works.
- Stainless Steel: Many parts of a good test indicator are made from stainless steel. This material is strong and resists rust, which is important for tools used in workshops.
- Hardened Steel: The contact point and other parts that experience wear are often made from hardened steel. This makes them very tough and resistant to damage.
- Brass: Some older or less expensive indicators might use brass for certain parts. Brass is softer than steel and can wear down faster.
- Plastic: You will often find plastic used for the dial face or the outer casing. Good quality plastic can be durable, but it’s less robust than metal.
Factors That Improve or Reduce Quality
Certain things make a test indicator better or worse.
- Smooth Operation: A high-quality test indicator feels smooth when you move the contact point. It should not feel stiff or jerky. This smoothness comes from good design and quality parts, like jeweled bearings.
- No Backlash: Backlash is a slight wiggle or play in the indicator’s movement. A good indicator has very little or no backlash. This is important for accurate measurements.
- Durability: Tools that are built well will last longer. Test indicators made with sturdy materials and good craftsmanship will hold up better to regular use.
- Brand Reputation: Well-known brands that specialize in measurement tools often produce higher-quality products. They have a history of making reliable instruments.
- Price: While not always true, a higher price often means better materials and more precise manufacturing. However, you can still find good value in mid-range options.
User Experience and Use Cases
Using a test indicator is straightforward once you understand how it works.
- Setting Up: You typically mount the test indicator on a stand or a magnetic base. Then, you bring the contact point into contact with the surface you want to measure. You adjust the indicator until the dial shows zero or a starting measurement.
- Taking Measurements: As the surface you are measuring moves, the contact point moves with it. The dial shows how much the surface has moved. This is useful for checking if something is flat, straight, or if it’s vibrating too much.
- Common Uses:
- Checking if a surface is level or flat.
- Measuring the runout of a rotating shaft or a wheel.
- Gauging the depth of a hole or a slot.
- Ensuring parts are aligned correctly during assembly.
A good test indicator is a valuable tool for anyone who needs precise measurements. By looking at the key features, materials, and understanding what makes a quality product, you can make a smart choice.
Frequently Asked Questions (FAQ) about Test Indicators
Q: What is the main purpose of a test indicator?
A: The main purpose of a test indicator is to measure very small movements or variations in the position of a surface.
Q: What does “dial reading” mean on a test indicator?
A: The dial reading shows you how much the surface being measured has moved. It’s like a tiny ruler that shows small changes.
Q: Why are jeweled bearings important in a test indicator?
A: Jeweled bearings help the indicator’s internal parts move very smoothly and last much longer. They reduce friction.
Q: Can I use a test indicator on any surface?
A: Yes, you can use a test indicator on most solid surfaces. The type of contact point you use can help with different surface textures.
Q: What is “runout” and how does a test indicator help measure it?
A: Runout is when something that should spin perfectly straight wobbles a little. A test indicator can measure this wobble as the object spins.
Q: Do I need a special stand to use a test indicator?
A: You usually need a way to hold the test indicator steady. This is often done with a special stand or a magnetic base.
Q: How do I reset the dial on a test indicator?
A: Most test indicators have a bezel or rim around the dial that you can rotate to set the needle to zero.
Q: What’s the difference between a dial indicator and a test indicator?
A: Dial indicators typically measure larger movements and are often used vertically. Test indicators are smaller and designed for measuring very small, often horizontal, movements.
Q: How accurate are test indicators?
A: Test indicators can be very accurate. Many can measure movements as small as 0.01 millimeters or 0.0005 inches.
Q: Where can I buy a good test indicator?
A: You can buy test indicators from tool supply stores, hardware stores, and online retailers that sell workshop tools and precision instruments.
