The Model 670 Fume Hood Monitor continuously senses air flow through the face of the fume hood, ensuring safe levels of fresh air are exhausting. The 670 provides a highly accurate hot wire sensor to detect very low flows common on fume hoods. The Model 670 comes with everything required to quickly install the unit including a mounting bracket, 24" of tubing for connecting to the inside of the hood wall and a 120 Volt AC power adapter.

Product Applications

  • Fume hood ventilation monitoring
Rated 1 out of 5 by from A very frustrating adventure in time wasting. The instructions sent with this device were clearly for a past model. The images of the PCB did not match, the CAL jumper was not as described, the buttons did not perform the way the instructions said they should. There was no way to set it up or make it work. I wasted many hours trying to figure this thing out. I cut a hole in the wall and the ductwork that all now need to be reworked to make the new alarm fit in the space. Communication regarding it's return was also weak, time consuming and frustrating.
