WM-1 Wall-Mount

Digital Pyrometers

The WM-1 is sturdy, accurate, easy to use, portable and dependable, making it the ideal molten metal temperature measuring instrument for ferrous foundries and steel plants. It can be used with molten Steel, Bronze, Cast Iron, Aluminum Alloys, Copper, Gold, Brass and Silver.

When the thermocouple is dipped in molten metal, the microprocessor reads the millivolts and mathematically converts it and provides the temperature reading. The indicator lamps (LEDs) on the front panel indicate and sound a buzzer when the correct reading is displayed. This entire process completes within 3 to 5 seconds, after which the thermocouple tip can be withdrawn.

The microprocessor studies the temperature values and detects the exact temperature of molten metal with its flat plateau detection method, thus rejecting variations due to slag temperature differentials, furnace hot spots, transient electrical spikes, etc. The WM-1 is used with SYSCON’s thermocouple tips. These tips are expendable temperature sensors in cardboard tubes.
