Measuring the temperature of molten metal in a foundry can be a slow and disruptive process. The use of disposable dip thermocouples can be both expensive and hazardous. The Meltmaster device from Land Instruments is claimed to be fast, accurate and easy to use and does not contact the liquid metal.

The Meltmaster is a handheld, non-contact temperature monitor that has been designed for use only in a metal foundry. Designed specifically for the foundry industry, it can directly lead to a reduction in the use of ‘dip’-type thermocouple systems used for periodic checking as required by process.

The device is suitable for the foundry environment, is robust and can resist heat and is battery operated (no trailing cables), with various accessories available.

Key features and benefits 

  • The Meltmaster measurement mode uses advanced, noise-rejection processing, which locks onto the real liquid metal temperature. Four measured temperatures can be displayed simultaneously: peak, valley, continuous and Meltmaster. 
  • Users can safely and accurately measure the temperature of molten metal in a melting furnace or during pouring without disrupting the process. The system can help to reduce operating costs while improving casting quality.
  • The Meltmaster requires only one hand to operate. Users can view the liquid metal stream through the viewfinder and pull the trigger; the measurement is made (in 30msec) and can be stored or output to a data logger (either connected or via Bluetooth).
