Vein Finders are optical devices that use the behavior of Infrared light to create an image and superimpose project it onto the viewing area. Infrared light is projected onto the viewing area and is absorbed at the locations where blood (veins) reside. Where light is absorbed there is less light reflected.

Our Multisensor Smoke Detector is an effective tool to detect the smoke at the incipient stage. These Multisensor Smoke Detectors are provided under the brand name of Context Plus XP95 multisensor detector. This Multisensor Smoke Detector contains an optical smoke sensor and a thermistor temperature sensor that has its outputs combined to give the final analogue value. The multisensor construction is similar to the optical detector but uses a different lid and optical moldings to house the thermistor temperature sensor. The sectional view (below) reflects the arrangement of the optical chamber and thermistor. The signals from the optical smoke sensing element and the temperature sensor are independent, and represent the smoke level and the air temperature respectively in the vicinity of the detector. The detector̢۪s microcontroller processes the two signals. The temperature signal processing extracts only rate of rise information for combination with the optical signal. The detector will not respond to a slow temperature increase, even if the temperature reaches higher level. An abrupt change in temperature can, however, cause an alarm without the presence of smoke, if sustained for 20 seconds. Download
