Review Title: Surgical Assistant
Comments: We utilize the product to monitor the temp and humidity in our operating room. The alarm is nice because the operating room is not utilized every day. But humidity is recorded every day to find future problems. These are all important to our operations because JCAH states that operations can only be performed in an operating room with specific temps and humidity.
