Light Emitting Technology™ (LET)

Better control, better results.



iWave® is a contactless, in-situ temperature technology that measures the sample temperature of each vessel in real-time. There is no need for a control vessel, fiber-optic probes, or wires. This new innovation utilizes Light Emitting Technology® (LET) that determines the temperature of the actual sample, rather than the vessel.


  • Temperature probe accuracy without the connection
  • The most advanced temperature sensor available
  • The easiest-to-use temperature sensor

CEM - iWave - How it Works

How it Works

1. Measures the Sample

iWave is proprietary technology that utilizes the emission of light from the sample (solution) to rapidly and accurately measure temperature. It reads the temperature of the solution itself, instead of reading the temperature of the vessel. This makes iWave the most accurate temperature sensor.

2. Floor Mounted Sensors

The iWave sensors are floor-mounted inside the cavity of the MARS 6 microwave digestion system. Every time a vessel rotates past an iWave sensor, the temperature is accurately measured in real time. This allows the advanced MARS 6 software to automatically make power adjustments to ensure you have a successful acid digestion.

iWave is as accurate as using a probe inside the vessel because it sees though the surface of the vessel and measures the light emitted from the liquid using LET technology.

iWave measures the temperature of the solution in all the vessels eliminating the need for a reference vessel.

It’s as easy as contactless sensors, but with the accuracty of a submerged probe.

Fiber-Optic Probe


As accurate as a temperature probe.

The data is in. When compared to the industry standard of fiber-optic temperature control, iWave is just as accurate. You get the exact temperature of every sample with precision and simplicity.

Cost Effective

You’ll save in many ways.

Save Time on Set-Up
If you’re accustomed to using a temperature probe, you know the hassle of setting them up. With iWave LET you get that same accuracy without taking the time to set-up the probes.

Save Time and Money
Before iWave, probes were the most accurate way to measure the temperature of a sample. To get results, probes are subjected to acid and high heat. Over time, probes will break and need to be replaced. This is costly, and can put a lab in a bind if a probe breaks and there are no spares handy.
