Force Gauges
Force Gauge Overview & How to Use
Force gauges, also known as "push-pull gauge" or "push-pull scale" are measuring equipment that measures the load (force) acting on a sample. They can measure tension, compression, bending, shear, as well as peel, adhesion, and friction. They are popular in manufacturing and play critical role in quality control and R&D, such as evaluation of mechanical properties of materials (strength, hardness, toughness, or durability), verification of safety and operability of parts and products, and compliance with industry standards.
Digital Force Gauges
Digital force gauges are with built-in load cells and used to measure compression, tension, peel, or coefficient of friction.
Digital force gauges feature data management on a PC and detailed analysis based on the data. Convenient functions such as pass/fail test, measurement time management, and memory are included. Some models can expand function by downloading optional software from IMADA-Connected.com.
We started manufacturing digital force gauges in 1986. With extensive know-how, we accommodate various measurement needs, from simple peak acquisition to those that can be used to create highly accurate graphs for force change analysis. For details, refer to the product list below.

Mechanical Force Gauges (Push Pull Gauges)
Mechanical force gauges, also known as "push-pull gauges" or ""push-pull scale, are analog force measuring device for spring mechanism and are used to measure push and pull forces.
Mechanical force gauges are easy to read the transition of force by the movement of the needle and can realize stable force loading. The robust construction and the power-source free makes them easy to store and manage, and that is the primary reason why mechanical force gauges are popular in many quality control sites. If your usage is limited, mechanical is recommended for its low-cost and easy storage.
IMADA mechanical force gauges are signature product and have been supporting manufacturing since 1947. See the details from the product list.
*Due to their spring-loaded structure, mechanical force gauges are not suitable for impact tests such as destructive tests. Digital force gauges are recommendable for such tests.

Torque Testers
Torque Tester Overview
Torque is the torsional moment (turning or twisting force) that acts on an object when it rotates, and the device that measures torque is Torque Tester. Torque testers can be used to measure opening and closing force, turning force, and sliding resistance, and indicate them in the unit of N-m, N-cm, kgf-m, kgf-cm, lbf-in, or ozf-in .
Torque measurement is popular, from the torsional strength of circuit boards, the tightening force of screws, the opening force of PET bottles and jars, and the operating force of rotary switches and keys, as a few examples.
Screw Cap Torque Testers
Screw Cap Torque Tester is the torque measuring instrument which measures the opening and closing torque of various container lids (screw caps) such as PET bottles and jars. It reads the turning force and displays a numerical value.
The table on which the measurement sample is fixed is available in a range of sizes, so it can measure not only the lid of a container, but also various other torques, such as the feed torque of lipstick or the operability of a volume switch.
For more precise torque measurement need, we offer a solution of automatically turning a measurement sample using a dedicated stand instead of handheld. Using a torque stand for torque measurement, especially in R&D, is highly recommendable, because the constant turning speed and accuracy improves the repeatability of measurement.

Handheld Digital Torque Gauges
Handheld Digital Torque Gauge is used to measure torque by holding the sensor by hand. Measuring the torque to tighten screws or to turn rotary switches are the most familiar examples. Although often confused, torque wrenches and torque screwdrivers are tools for tightening screws at the appropriate torque value, whereas torque gauges are measuring equipment that quantify how much torque is actually applied. Torque gauges are measuring equipment used on sites of quality control and research and development to improve operability, strength, and comfort.
The sampling speed is as fast as 2000 Hz, so it accurately captures peak values and outputs smooth and highly useful data when graphing changes in torque values.
A jig (attachment) can be attached to the tip of the sensor. Selecting an attachment of the appropriate shape for the sample is important. Various attachment shapes are available to accommodate a range of samples. We offer custom-made attachments as well.

We offer two types: 1) a handheld that measures by twisting the sensor by hand, and 2) a desktop that can automatically rotate at a digitally set speed.
Attachments, Grips & Fixtures
Attachment, Grip & Fixture Overview
An attachment is a jig that is attached to a test stand or a test stand of a force gauge. Since it is the part of the attachment that actually contacts the sample to be measured, the attachment is a very important element in force measurement.
A force gauge can be used to measure compression force by attaching an attachment for compression test, and can measure tension force by replacing it with an attachment for tension test. In other words, a force gauge can read a force value, but the type of force to be measured is determined by the attachment, not by the force gauge.

Food Texture Analyzer & Related
Food Texture Analyzer (Rheometer)
Rheometer is a tester that quantifies the texture (mechanical properties such as hardness, elasticity, and adhesion) of food. Texture is a key factor in creating good taste, just as potato chips that are soggy do not taste good. Numerical control of texture, such as crispiness and stickiness, can stabilize the taste and quality of food products. Demand for texture test is increasing, and we recognize it as a sign that consumers are becoming more sensitive to texture.
Recently, with the aging of the population worldwide, increasing number of food products are being measured for texture and hardness from the perspective of whether they are easy to chew even for elderly people with weakened masticatory skills. As a result, industry standards for ease of chewing, such as "food for people with dysphagia" and "universal design food," have emerged.
IMADA rheometers (food texture testers) are programmed for easy measurement in accordance with these standards.
In addition to the rheometer, we also offer a simple unit to manually measure food hardness.
