How should the thermistor probe be cleaned?
The D501 Thermistor probe may be disinfected and sanitized by washing in 3% hydrogen peroxide or 70% isopropanol. 70% ethanol is nearly as effective, but 100% alcohols are less germicidal. Dakins solution (sodium hypochlorite in neutral buffer) is also suitable. Brief immersion of the probe in detergent solutions is not harmful. Activated dialdehyde solutions, such as Cidex, are also effective. Probe plugs and connectors should not be
immersed. The thermistor probes are NOT suitable for boiling, autoclaving or EtO sterilisation. During cleaning the probe should be handled gently. When wiping clean, hold the probe in one hand at the sensing tip and wipe the probe and lead wire toward the plug end. Excessive pressure could stretch the covering and break the internal wires, which would destroy the probe.
