Cautions
The TL2 and associated temperature probes are sensitive devices and should be handled with care. Care should be taken not to
submit the temperature probes to mechanical shock, over-heating or exposure to fluids at the probe to cable interface. Overheating
the probes beyond their calibrated temperature range, damage and/or contamination may cause sensor drift and instability.
Authorized Service
Service and Calibration should only be performed by ThermoProbe, Inc. or an authorized distributor.
