I need to buy a telemetry system and I need help. I want DSI but I have better price offers. My problem is that I do not know if the data provided by other producers are real or not.
In grad school the Shekhar, Gehlert and DiMicco labs studied rat models of stress and panic disorders. Although a Beckman Dynograph was employed to monitor blood pressure and heart rate most for many experiments, telemetry was used for some. In the publication of the attached file, "BP and HR were measured by directly implanting telemetric probes into the abdominal aorta, which contains a pressure transducer (catalog #C50-PXT; Data Science International, Arden Hills, MN)." In some unpublished data, which I observed, the same telemetry system was used to monitor activity in addition to BP and HR. The DSI produced beautiful data. The Beckman equipment is probably obsolete now, and unfortunately, I cannot address limitations of other telemetry systems. Best wishes for every success, -Sherie
My lab has extensive experience with the DSI system. They have great customer service and recently upgraded their units to have better battery life and a few convenient features for easy calibration and fast setup. We've collected high-quality data, but it is an expensive system. There are other companies you can check out for price comparisons. Millar is another popular system for small animal and rodent telemetry, though I personally do not have experience with them.
Dependent on what you are looking to analyze and animal model you may want to look into the Kaha or Indus telemetry systems as well. They offer a wide range telemeters and should suffice for a variety of studies.
