| Emissivity The infrared energy emitted by a surface differs according to its composition and physical condition. The parameter, used to characterize the object surface, is called emissivity. The preset value 0.95 is valid on most common applications with few exception like shiny metals (e.g. chimney can be measured by painting a small area or sticking a small label). Emissivity can also be adjusted from 0.2 to 1. Laser Sighting US Ultra Sharp All MicroRay models are equipped with a Class II Laser for aiming purposes. The offset laser sighting will allow you to identify the approx. center of the target being measured. The Ultra Sharp definition of laser makes it easier to read outdoors as well. 9V Battery Easily replaceable standard 9V battery is provided with the unit. A kit is also available for rechargeable battery and external charger. Tripod mounting Standard photographic tripod thread is available for accurate and long term measurements. Built-In Contact Probe The MicroRay HVAC+ is equipped with a connector for contact measurement. The available temperature probes include a Contact, Immersion, Penetration, and Ambient Air. One compact probe can actually be stored inside the unit for easy access. Longer probes are available if needed and provided with a wire connection. Built-in T+RH% sensor The MicroRay HVAC++ is equipped with a sensor for ambient Temperature and Relative Humidity measurements. The internal Sensor allows to check the comfort index in offices and living rooms. Ranges: -10 to 50°C - 10 to 95%rH Accuracies: ±0.5°C - ±3%rH Memory The MicroRay HVAC++ model can store up to 64 test with date and time using the internal real time clock. Data logging can be manual or automatic with settable sampling time. |
