Accurate temperatures can be obtained even when the target is 90% obstructed. The PMP-716 uses a visible laser to assist in aiming and a microprocessor to set up parameters like emissivity, slope, response time, sampling mode etc. It also has an interior ambient temperature compensation unit, which allows the instrument to work in temperatures of 0~50°C (32~122°F).

Logika Technologies Inc. Model PMP-716 Operator’s Manual Rev 1.2 Aug-13 • Automatically compensates for changes in target emissivity or varying distance from the target to detector. • The target does not need to fill the detector’s field of view to accurately measure the target temperature, allowing flexibility of pyrometer location and target position variability.
Logika Technologies Inc. Model PMP-716 Operator’s Manual Rev 1.2 Aug-13 If the object remains at a stable temperature, the ratio of the radiation energy remains constant. When the target temperature varies, the two wavelength ratio will remain the same. However, the slope of the ratio change differs when measuring different objects (like metal and non-metal), so a two-color slope coefficient is needed for correction.
3. Location Sensor Location The Logika PMP-716 Pyrometer should not be used above a heat source for extended periods of time. Avoid direct exposure to water vapor or excessive dust or smoke The Logika PMP-716 should be used close enough to the target to allow enough infrared energy to reach the detector in order to provide a strong signal, but far enough from the target to minimize the amount of heat that reaches the enclosure’s electronics.
Figure 3.1: Pyrometer Distance Graph Sensor Aiming Use the pyrometer’s visible aiming laser to properly align the PMP-716 with the target. Typically, the pyrometer should be centered on the target. At the same time, adjust the detection spot by aiming laser to avoid interfering sources of infrared energy, including reflection of hot metal or sunlight.
