Temperature Measurement of Liquid Metal

Cyclops 055 L Portable Liquid Metal Thermometer

Cyclops 055L Meltmaster

What is the Meltmaster mode?

The 'Meltmaster' measuring mode uses an advanced, noise rejection processing mode which locks onto the true liquid metal temperature. This mode allows the real liquid metal temperature to be measured, ignoring the high temperature sparks, low temperature water vapour, dust and smoke, that typically cause an error in the real liquid metal temperatures.

Accurate sighting is ensured by the clear, wide angle (9°) field of view and small, clearly defined (1/3°) measurement area.

Focusing is fixed at 5m / 16ft.

Emissivity compensation is provided via the icon-based menu system.
The operating waveband has been carefully chosen to minimise errors due to uncertainty in emissivity and the effects of atmospheric vapour components. Significantly reduces the use and cost of disposable ‘dip’ type thermocouples.
The Cyclops 055L  features standard user-friendly Bluetooth® wireless communications or a USB connection for PCs or Mobile.

*Data Output Modes

  • Single mode: logs a measurement for each trigger release
  • Latch mode: logs continuous, average, peak and valley readings from the first trigger release until the second
  • Burst mode: logs a stream of measurements whilst the trigger is held pressed - approximately 30 readings / sec, up to a maximum of 999 readings per burst.
  • Route mode: This mode is ideal for users who need to take a number of readings on a regular tour of their plant or process. The pre-loaded locations help to guide the user along each route
