Cyclops 100 L - High Temperature applications

Cyclops 100 L Handheld Furnace Thermometer

The measured temperature is displayed in four simultaneous modes: continuous, peak, mean and valley, with user selected mode for the viewfinder display. Temperature measurement resolution to 0.1°.

Accurate sighting is ensured by the clear, wide angle (9°) field of view and small, clearly defined (1/3°) measurement area. Focusing is variable from 1m to infinity, with close focus options available using auxilliary lenses.

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.

The Cyclops 100L  features standard user-friendly "Bluetooth®" wireless communications or a USB connection for PCs or tablets.

Get it on Google PlayThe Land Cyclops Logger Software allows you to connect a Land Cyclops portable pyrometer to a mobile device and view, analyse and record live temperature readings. Get the software here for free.

As standard, the Cyclops C100L is now supplied with a designated three point UKAS certification to ISO / IEC 17025:2005 plus heat-resistant / thermal protective jacket to provide protection against excessive heat and dust. More information.

Key Benefits

*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.
