Height meter, how to choose the best and cheapest?

November 2, 2021

The height gauge is a laboratory instrument used to obtain precision measurements. Also known as height gauges, they come in two forms: digital and analog. Both models fulfill the same functions of calculating millimeter graduations.

The meter, today, is used in various fields, but especially in medicine to achieve the height of patients. They vary in size and appearance, as they have evolved over time. However, they remain good instruments for chemistry and physics laboratories in various studies and practices.

If you want to know everything related to height gauges you are in the right place. In the following article we will address the essential characteristics of a height gauge taking into account its use and construction structure. We recommend that you stay until the end, as we will mention the advantages and disadvantages of this particular instrument.

What is a height gauge?

A height gauge, or height gauge, is a laboratory instrument that is part of the group of metrology devices . Its main function, as its name suggests, is to trace the symmetry and height of an object or person. It is also used as a quality control for the shafts of a drill or in machining excesses.

For the previous dimensioning, a gauge is included with a burin, so that more accurate precisions are achieved. The scale used for these laboratory devices is the Vernier scale, which are fast and accurate measurements that are included in the structure. On the other hand, they have a probe and a surface that works as a reference point to carry out the corresponding measurements.

Essential Features of a Height Gauge

Next, we will talk about the characteristics of a height gauge to give you an idea of ​​what type of instrument it is.

  • Most, if not all, types of height gauges have a main scale. Which is adjustable and helps to plot the measurements. It can be adjusted from zero to any other reference point.
  • The surface of the gauges, which are tempered and polished, have a base to track or detect displacement.
  • The material with which these meters are made varies according to the manufacturers, but it is generally a stainless steel that lasts longer. They have a built-in satin which reflects the sunlight so it doesn’t get in the way when work is being done.
  • The traditional method of reading the scales of a height gauge does not change in reference to vernier calipers. Both have a metric scale in which the corresponding height strokes can be made. They are accurate to 0.001 inches and have divisions ranging from 25 to 50.

What does a height gauge look like?

The height meter is a metal object that consists of a main column at the top that is graduated in millimeters and centimeters depending on the size of the object itself. This column can be raised or lowered thanks to the fact that it slides through the tracer. Which has a built-in precision vernier, as mentioned above.

In order to check the parallelism or the horizontality of the objects or people that are on the flat surface, the type of grammar is exchanged with a leveling probe . This prevents the accuracy of the measurement from being lost. Today they are incorporated in some digital panels that indicate the height of objects. However, analogs are still well regarded, especially in laboratories.

Types of height gauges

In the next section we will talk about the various types of height gauges that exist. According to the characteristic of the instrument, finding the following classifications:

Vernier meters

Mechanically manufactured laboratory apparatus for linear measurements outdoors. It is also used indoors, but especially in the depths is when it is most used.

Dial gauge

It is a type of meter that is incorporated with a dial indicator that facilitates the reading of the measurements made. This replaces the already well-known verniers that, among other types, are incorporated into those of Vernier.

Meter with dial and counter

The construction of this height gauge is similar to the dial gauge. In fact, they work the same way to make the height precisions. However, unlike the one already mentioned, this one uses an indicator amplification system consisting of an amplifier gear and a center pinion. On the other hand, the counter is giving readings of the fractions on the face.

Digital Meter

The digital meter is a type of modern measuring instrument that comes incorporated with some technological facets that allow accurate and immediate tracing. Digital is subdivided into two species, one that uses a two-column rotary encoder to detect displacement on the surface.

The other type of this same meter has a displacement detector on the training surface. And, unlike the other model, it only has a single column in a rectangular section. They are the most used today and are even incorporated into clinics.

How to use a height gauge

In order to use a height gauge you must follow the following steps:

  • First, the clamping screw of the meter slider must be tightened to prevent it from shifting from one side to the other while it is being used.
  • Second, you have to move the stroke using the lever-type dial indicator. Avoid moving the stroke forward or backward as it will cause precision errors.
  • Third, you have to use a fine feed to be able to secure the position once you locate the line at the desired height.

Advantages and disadvantages of a height gauge

The meter is a great instrument that works for various fields including medicine. Among some of the known advantages we have that they do not require electrical energy unless it is digital with a plug. They are not very sophisticated objects and are easy to see when the value increases or decreases.

However, meters are not perfect machines. Regarding the disadvantages, we find that they have low resolution, they do not provide three measurement figures , there is a parallax error that limits the accuracy to more than 0.5% of the scale and the readings present serious errors when the instrument has several scales.
