All ACI thermistors and RTD Room or Space temperature sensors are both non-polarity and non-position sensitive. All thermistor type room units are supplied with a two-pole terminal block and all RTD's and 592 temperature sensors will be supplied with either a two or three-pole screw terminal block. ACI Recommends the use of 18 to 20 AWG twisted pair wire or shielded cable for all sensor installations.
Beyond standard air temperature, surface temperatures of walls, ceilings, floors, and objects within a space can significantly affect the comfort level within a space. These surfaces can also be responsible for considerable heat transfer with nearby air and other objects. In this category, you will find tools for quickly determining the surface temperature of nearby objects and surfaces, as well as meters for long-term reading and logging of nearby surface temperatures.
Measures remote surface temperatures to 932°F (500°C) with 30:1 distance to spot ratio and Laser pointer; Simultaneous display of Air Flow in CFM/CMM or Air Velocity plus Ambient Temperature
Just point, shoot, and read the temperature of transformers, motors, pumps, panels, breakers, compressors, duct, steam lines, valves, and vents. Its small size and versatile features make it extremely easy to use. The accurate infrared technology and dual lasers provide a 12:1 distance to spot ratio, making it easier to accurately measure temperatures in hard to reach areas.
