Ultrasonic Hardness Tester SONOHARD - SH-21B
Checkline SH-21B – Portable Hardness Tester
The Checkline SH-21B is designed for accurate hardness testing in areas that are difficult to access using conventional hardness testers. Its compact design makes it well suited for testing compact components, metal castings, gears, crankshafts, and a wide range of metal parts.
The instrument is also suitable for on-site inspection and maintenance of large structures and equipment. Typical applications include vehicles, ships, steel towers, bridges, aircraft, and other large-scale metal structures.
With its ability to perform hardness measurements directly on components and structures, the SH-21B provides a practical solution for quality control, inspection, maintenance, and field testing.
- Fast and efficient measurement: Obtain hardness readings within just a few seconds.
- Minimal surface impact: The measurement method creates an extremely small indentation of approximately 0.1 mm², making it suitable for testing finished or precision-machined components.
- Multiple hardness scales: Results can be displayed in HV (Vickers), HRC (Rockwell), HS (Shore), and HB (Brinell) scales.
- Tensile strength conversion: Hardness values can be converted into estimated tensile strength in N/mm².
- Reliable measurements: Readings remain consistent and are not significantly influenced by the material or surface beneath the test specimen.
- Large data storage capacity: Up to 2,000 measurement results can be stored in the instrument's memory and transferred to a PC for further analysis and record keeping.

IR pyrometer TB-1650
Infrared Thermometers allow users to measure temperature in applications where conventional sensors cannot be employed. Specifically, in cases dealing with moving objects (i.e. Rollers, moving machinery or a conveyor belt), or where non- contact measurements are required because of contamination or hazardous reasons (such as high voltage) where distances are too great, or where the temperature to be measured are too high for thermocouples or other contact sensors
IR Pyrometer Model: TB-880
The IR Thermometer measures and displays non-contact (Infrared) temperature readings up to 1616°F
(880°C). The Built-in laser pointer increases target accuracy while the backlit LCD and handy push-buttons
combine for convenient, ergonomic operation. The Type K Thermocouple input provides contact
measurements up to 1999°F (1400°C)*. The adjustable emissivity feature allows the IR thermometer to
measure the temperature of virtually any surface. This meter is shipped fully tested and calibrated.
IR Pyrometer Model: TB-550
TB-550 is a low cost infrared thermometer for non- contact temperature measurement of an object. Just by pointing the thermometer on to the object and pressing a trigger, surface temperature of the object is instantly displayed on the LCD Panel. TB-550 can also compute max & min temperature reading of the surface. Built-in laser pointer helps to aim the target object.
IR Pyrometer Model: TB-1100
TB-1100 is a low cost infrared thermometer for non-contact temperature measurement of an object. Just by pointing the thermometer on to the object and pressing a trigger, surface temperature of the object is instantly displayed on the LCD Panel. TB-1100 can also compute max & min temperature reading of the surface. Built-in laser pointer helps to aim the target object.
IR Pyrometer Model: TB-1300
TB-1300 is a low cost infrared thermometer for non-contact temperature measurement of an object. Just by pointing the thermometer on to the object and pressing a trigger, surface temperature of the object is instantly displayed on the LCD Panel. TB-1300 can also compute max & min temperature reading of the surface. Built-in laser pointer helps to aim the target object.
DIAS portable pyrometer
Portable pyrometers of DIAS PYROSPOT series 80 are suitable for the usage in heavy industry under rough conditions. You are able to reach every measurement point with this portable and robust device and you stay flexible. Together with an integrated video module a color TFT display enables an easy and correct alignment of the pyrometer to the measuring object. This is safer – especially in harsh industrial environments than the view visors often used in high temperature pyrometers.
Sensortherm portable Pyrometer
Robust handheld IR thermometers for non-contact temperature measurement in the short-wave spectral range, especially suitable for measurements on shiny metals.
KTL series PORTABLE/ONLINE Pyrometer
KTL series infrared radiation thermometers are combination of highly durable sensor, reliable
microprocessor electronic and precision camera optics. It is provided with four measuring modes
Cont/Peak/Valley & Hold. Measured readings are displayed on LED both inside the viewfinder and on side
panel of the thermometer. Variable sampling rate can be set from 0.01 to 1.00 seconds allowing fast
response or facilitating smooth readout if target temperature is rapidly changing. Analog and digital outputs
are available as standard. PC communication software is included as standard accessory.
