Metravi PRO 65 MAX Plus Non-contact Industrial Pyrometer with Circular Laser

A. Product Overview

The Metravi PRO 65 MAX Plus is a professional industrial infrared thermometer and pyrometer used for measuring surface temperature without physically touching the target. It also supports contact-temperature measurement through a compatible Type K thermocouple.

Its circular laser system uses multiple laser points to show the circumference of the measurement area. This helps the operator identify the exact surface area being measured instead of relying only on estimation.

The infrared temperature range is from minus 50°C to 1000°C, while the Type K input supports contact-temperature measurement from minus 50°C to 1370°C. The instrument offers a fast response time of approximately 150 milliseconds and a 20:1 distance-to-spot ratio.

Key features include:

• Circular laser targeting
• Non-contact infrared temperature measurement
• Type K contact-temperature input
• Infrared range from minus 50°C to 1000°C
• Type K temperature range from minus 50°C to 1370°C

• Adjustable emissivity from 0.10 to 1.0
• Maximum, minimum, average and difference temperature display
• Settable high and low temperature alarms
• Automatic data hold
• Backlit LCD

The instrument is designed for industrial inspections, maintenance work and applications where hot, moving, hazardous or inaccessible surfaces must be checked safely.

B. Working Principle

The Metravi PRO 65 MAX Plus works by detecting infrared energy naturally emitted by the surface of an object. Its infrared sensor receives this energy and converts it into a temperature value shown on the LCD.

The circular laser is used only for targeting. It creates a visible circular pattern that indicates the approximate measurement area. As the distance between the thermometer and the target increases, the measured spot also becomes larger.

The 20:1 distance-to-spot ratio means that at a distance of 20 units, the approximate measurement spot has a diameter of one unit. For example, at a distance of 480 millimetres, the spot diameter is approximately 24 millimetres.

For reliable results, the target surface should be larger than the measurement spot. The thermometer should also be positioned so the circular laser remains fully within the required target area.

Different materials emit infrared energy differently. The adjustable emissivity setting allows the instrument to compensate for the surface characteristics of the material being measured. Emissivity can be set between 0.10 and 1.0.

When a Type K thermocouple is connected, the instrument measures temperature through direct contact. The thermocouple generates a small electrical signal corresponding to the temperature at the probe tip, which the thermometer converts into a digital reading.

C. Why It Is Used

The Metravi PRO 65 MAX Plus is used when temperature must be measured quickly, safely and without interrupting the process.

It is particularly useful when:

• The surface is too hot to touch
• The equipment is moving or rotating
• The target is electrically live
• The surface is difficult to reach
• Contact measurement could contaminate the product
• A large number of temperature checks must be completed quickly
• Temperature differences between components must be identified
• Equipment must be inspected during operation
• High-temperature alarms are required during maintenance
• Both surface and contact-temperature measurements are needed

The maximum, minimum, average and difference functions help users compare readings during inspections. The high and low alarms provide an immediate indication when a measured temperature moves outside the selected limits.

Its rapid response and circular laser targeting make it suitable for preventive maintenance, troubleshooting, process inspection and thermal-condition monitoring.

Frequently Asked Questions

1. What is the Metravi PRO 65 MAX Plus?

The Metravi PRO 65 MAX Plus is an industrial contact and non-contact temperature-measuring instrument. It measures surface temperature through infrared sensing and supports contact-temperature measurement with a Type K thermocouple.

2. What is the infrared temperature range?

Its non-contact infrared measurement range is from minus 50°C to 1000°C.

3. What is the Type K temperature range?

The Type K thermocouple input supports measurements from minus 50°C to 1370°C, depending on the connected thermocouple and its specified operating range.

4. What is circular laser targeting?

Circular laser targeting uses multiple laser points to outline the measurement area. It helps the user position the thermometer accurately over the required target.

5. Does the laser measure temperature?

No. The laser is used only for aiming and indicating the measurement area. Temperature is measured by the infrared sensor.

6. What is the distance-to-spot ratio?

The Metravi PRO 65 MAX Plus has a 20:1 distance-to-spot ratio. This means the spot diameter is approximately one-twentieth of the distance between the thermometer and the target.

7. Can it measure temperature from a distance?

Yes. It can measure surface temperature without contact, provided the target is larger than the measurement spot and there is a clear line of sight.

8. Can it measure internal temperature?

Infrared measurement only detects surface temperature. Internal temperature can be measured using an appropriate Type K contact probe where the application permits.

9. Does it have adjustable emissivity?

Yes. The emissivity can be adjusted digitally from 0.10 to 1.0 for different surface materials.

10. Why is emissivity adjustment important?

Materials emit infrared energy at different rates. Adjusting emissivity helps improve measurement accuracy when checking different surface types.

11. Can it measure shiny metal surfaces accurately?

Shiny and reflective metals can produce inaccurate infrared readings because of low emissivity and reflected thermal energy. Emissivity adjustment, surface preparation or a suitable contact probe may be required.

12. Does it have high and low temperature alarms?

Yes. The user can set high and low temperature limits for faster identification of abnormal conditions.

13. What do the maximum, minimum, average and difference functions do?

These functions display the highest, lowest, average and difference values recorded during a measurement session. They are useful for comparing temperature variations across equipment or surfaces.

14. How fast is the measurement response?

The instrument has a response time of approximately 150 milliseconds.

15. Is it suitable for industrial environments?

Yes. It has an IP54-rated housing for protection against dust and water exposure and has been tested for drops from a height of two metres.

16. Does it include automatic data hold?

Yes. The automatic data-hold function temporarily retains the measured value on the display after the trigger is released.

17. Does it have a backlit display?

Yes. The backlit LCD improves visibility in poorly illuminated working areas.

18. What type of batteries does it use?

The Metravi PRO 65 MAX Plus operates using two 1.5 V AAA batteries.

19. Can it be used for electrical-panel inspection?

Yes. It can be used to identify abnormal heating in electrical panels, terminals, breakers and connections. Appropriate electrical safety procedures must still be followed.

20. What are the common applications of the Metravi PRO 65 MAX Plus?

Common applications include electrical-panel inspection, machinery monitoring, furnace checks, HVAC servicing, refrigeration maintenance, automotive diagnostics, production-line inspection, hot-surface testing and preventive maintenance.
