I am looking into getting a system for monitoring our Transfusion Service Refrigerators, Freezers, and Platelet Incubator temperatures.

(We also could probably include all of the Lab refrigerators & freezers.)

I would appreciate opinions about any of the systems out there... Rees, etc.

Thanks,

We are currently using the Mack Lablink System (Mack Information Systems, Inc.) in our blood center. We use it for monitoring refrigerators, freezers, platelet incubator/doors, production room temps, IS server room temps and even have an adapter (Mack's) for our BacT/ALERT Bacterial Detection system. The equipment has proven very reliable and the vendor support is excellent (tech support and repairs). We are moving to their Plexxium System in the near future and that system looks very promising. Quality control monitoring (calibration verification) is also fairly easy to perform.

Good luck in your search.

Could you give me an idea of about how much an automated temperature monitoring system would cost? Is each probe/harness sold separtely and if so how much?

Your input is appreciated.

Thanks, MWL

We have used the Plexxium system for a year now. Initially there were a few bugs but they have been worked out. Most of these problems had to do with learning what to set the limits at for the eqipment. For instance some freezers have a defroast cycle so they get a little warmer at specific intervals. A small incubator has larger temperature fluctuations normally that a large incubator. Also placement of the probe in the equipment is important. We had difficulty identifying a good medium to use for the probe for the -70 degree freezer. We ended up placing a test tube in cooking oil and placing the probe in there. We are very satisfied with the system and the support. We have attached about 32 pieces of equipment to the system for the whole laboratory and have one remote location. We monitor incubators, RT, freezers, one -70 degree freezer, platelet incubator and refrigerators. Having a monitoring system sometimes is annoying for the techs when the alarms go off but it is amazing what is going on in the equipment over 24 hours. It really is a good way to head off problems.

:confused:We have been trying to test alarm activations and the numbers seem to always be off. We have the Isensix system. Has anyone had any sucess? What kind of temperature monitoring device was used to test the temperature ex. probe thermomter?
