Is anyone using a cellphone or Nextel near the equipment?

I have a problem about a Cryo temperature monitor. The probe's
capability is to monitor -95C to -1C.
There are spikes of two probes for monitoring -20C deepfreezers, while
the temperature is stable indeed. Are there any Electromagnetic
Interferences?The cables are well earthed. How to resolve this problem?
Thank you very much!
