testo Inc. (Sparta, NJ) has released two new thermal imagers, the testo 875 and testo 881, which can be used for diagnostics in building performance, predictive maintenance, and thermal anomalies. The testo 881 was designed with the maintenance professional in mind, with a <0.05°C NETD sensitivity, voice recording, a telephoto lens, and an integrated digital camera. In contrast, the testo 875 has HVAC/IAQ and weatherization in mind, with a thermal sensitivity of <80mK, a full-sized 160x120 focal plane array, and a large 3.5” display. Both of the imagers use testo’s TwinPix software, which blends both the thermal image and visual image into one.
