Infrared Temperature Sensor with Vario-Zooom Focus and Ttl/Slr Intra-Optical Light Sighting Introduced by Everest Interscience

Share Article

Everest Interscience's new Infrared Temperature Sensor, Model 6000.2, incorporates two unique features. The first is their Vario-Zooom automatic focus which makes it possible to use the infrared sensor for a variety of applications. The other is their patented TTL/SLR Intra-Optical Light Sighting feature that provides a pulsating, safe LED light that pinpoints the exact area being measured. The Model 6000.2 is available in both a low- and high-temperature configuration with a variety of outputs.

Everest Interscience of Tucson, AZ, has released a new upgrade of their Series 6000 Infrared Temperature Sensors on the Model 6000.2. This is a new precision infrared temperature measurement sensor that features their Vario-Zooom automatic focus (Patent Pending) and their patented TTL/SLR Intra-Optical Light Sighting.

To adjust the focus of the Series 6000 sensors, the end-user slowly pushes the front optics in or pulls it out, respectively, to reduce or increase the size of the field of view. After the desired focus has been established, the focus can be locked in place with a provided Allen wrench.

A patented Through-The-Lens/Single Lens Reflex (TTL/SLR) feature, wherein a Light Emitting Diode (LED) passes visible light through the same path as the infrared beam, shows a flashing light on the target. This LED shows the targets location, shape, size and surface texture, thus taking the guesswork out of knowing where the infrared temperature sensor is looking.    

The sensors are housed in a stainless steel case that is only 7/8 in diameter and 2-1/2 long at infinity focus. The signal and power conditioning are housed in this miniature sensor.

The Model 6000.2 comes in both a high-temperature formation (Model 6000.2H) and a low-temperature formation (Model 6000.2L). The temperature range for the Model 6000.2H is -40C to 1100C or -40F to 2000F. The temperature range for the low-temperature Model 6000.2L is -40C to 100C or -40F to 200F. They have resolutions of 1.0C or 1.0F and 0.1C or 0.1F, respectively. The accuracy for the Model 6000.2H is 1% of Reading 1 and ?0.5C or 0.5F for the low-temperature Model 6000.2L.

Their optical configuration is robust, aerospace-quality, double-coated Zinc Selenide Optics per Military Specification MIL-C-13508. They operate in the 8 < Wavelengths < 14 Microns spectral passband. The standard field of view for the high-temperature infrared temperature sensor is 2 or 15 and 4 or 15 for the low-temperature. The are capable of measuring target sizes from one-half millimeter.

All standard outputs are available: Millivolt, Milliampere, J or K Thermocouple, or RTD. The current output models have a single-wire, loop-powered interface. Both the power and the signal can be carried on one shielded wire.

The low-temperature instruments are used in a variety of applications for the natural environment. These include agronomy, entomology, biology and medical applications. The high-temperature instruments are used for industrial applications.    

Everest Interscience has a complete line of both hand-held and fixed-mounted infrared thermometers and temperature sensors in their product line. Also, Everest manufactures a portable calibration source (Model 1000) that can be used to accurately verify the accuracy of any infrared thermometer in the field. All of these instruments can be viewed at the Everest website at
