Large Screen Digital Pyrometer for Molten Iron, Steel and Non-Ferrous Metals

The CYY-W600 Large Display Molten Metal Pyrometer is a fixed, wall-mounted temperature measurement instrument designed for foundries, metal melting shops and metallurgical applications where molten metal temperature needs to be measured quickly and clearly at the furnace.

Unlike a small handheld thermometer, the CYY-W600 uses a 5-inch large digital display with approximately 120 mm high digits, allowing the measured temperature to be read from a distance. This makes it particularly suitable for furnace-side temperature measurement where operators need to see the result while standing away from the measurement point.

The CYY-W600 can be configured for different molten metals and temperature ranges by using compatible rapid thermocouple probes.

It can be used as a:

Large Display for Easy Reading from a Distance

One of the main advantages of the CYY-W600 is its highly visible display.

The instrument uses a 5-inch large digital display, with digits approximately 120 mm high and 66 mm wide. The design is intended for long-distance viewing in a foundry or melting workshop.

The display can normally be installed approximately 10 meters from the measurement point in a direct line of sight, while an installation height of approximately 2–4 meters is recommended according to the operating manual.

This makes the CYY-W600 particularly useful when:

Large Screen Pyrometer for Foundry Temperature Measurement

In international foundry terminology, molten metal temperature measurement is commonly described using terms such as molten metal temperature measurement, pyrometer, temperature measurement instrument, melting and casting temperature measurement.


The CYY-W600 is designed for the same general application category, but with a large fixed display and wired measuring connection for furnace-side operation.

Molten Iron Temperature Measurement

The CYY-W600 can be configured for molten iron temperature measurement using suitable rapid thermocouples.

This makes it suitable for:

The instrument can display the temperature clearly while the operator performs the measurement at the furnace or ladle.

For iron foundries, a large display can also make the measured temperature easier for supervisors and production personnel to observe.

Molten Steel Temperature Measurement

The CYY-W600 can also be configured for molten steel temperature measurement.


Molten Copper Temperature Measurement

The CYY-W600 can also be configured for molten copper temperature measurement.

The product documentation lists suitable Pt-Rh and CYY thermocouple configurations for molten copper applications.

For copper melting workshops, the large digital display allows the operator to check the measured temperature without having to stand close to a small instrument display.

Molten Aluminum Temperature Measurement

For lower-temperature non-ferrous metal applications, the appropriate thermocouple configuration should be selected according to the required measurement range.

Customers should specify the metal material and required temperature range when ordering the CYY-W600 so that the instrument and measuring probe can be configured correctly.

The manufacturer specifically requests customers to specify the material being measured and the required temperature range when ordering.

Wall-Mounted Large Display Design

The CYY-W600 is designed as a wall-mounted molten metal temperature measurement instrument.

The large display can be mounted on a wall at a suitable viewing position near the furnace.

Recommended installation conditions from the operating instructions include:

This configuration allows the temperature display to remain visible while the measuring operator works at the furnace.

Wired Temperature Measurement System

The CYY-W600 uses a wired connection between the large display instrument and the measuring gun.

The measuring gun is connected through the instrument's aviation connector, and the measuring lance is available in approximately 2.5–3.3 m configurations.
For foundries that prefer a simple wired system without wireless communication, this provides a straightforward installation and operation method.

Automatic Temperature Detection and Hold

The CYY-W600 Its internal processing system automatically handles the typical molten-metal temperature curve, including rapid temperature increase, overshoot and stabilization.

The instrument calculates the stable temperature value automatically and displays and holds the result. When the measurement is completed, the electric bell provides an audible indication to the operator.

This helps make the measurement process easier to operate in a busy foundry environment.

Fast 3 Second Temperature Measurement

During measurement, the thermocouple is inserted into the molten metal to a recommended depth of at least 20 mm.

The normal measurement time specified in the manual is approximately 2–5 seconds.

When the bell sounds, the operator should immediately remove the measuring gun. The CYY-W600 then automatically displays and holds the measured temperature.

Anti-Interference Design for Induction Furnaces

The CYY-W600 is designed with anti-interference measures for demanding melting environments.

According to the product documentation, the instrument can perform temperature measurement in an intermediate-frequency induction furnace while the furnace is energized, without requiring the furnace power to be switched off.

This feature is especially relevant for foundries using induction furnaces for iron, steel and other metals.

Why Use a Large Display Molten Metal Pyrometer?

A conventional handheld temperature meter is useful when only the operator needs to see the measurement.

A large-display pyrometer is more useful when the temperature needs to be visible to multiple people in the production area.

The CYY-W600 can help:

The product documentation also notes that the large-screen design can help monitor on-site operator operation and strengthen internal production management.

Typical Applications

The CYY-W600 can be used for:

Iron Foundry

Molten iron temperature measurement in melting furnaces and before pouring.

Steel Foundry
