The probe is connected to a 5.0m lead.Temperature Range: -40°F to +257°F / -40 to +125°CSensor Type: PST (Thermistor)Connector Type: Lumberg (6-Pin)Warranty: 6 Months Tag: OBSOLETE PRODUCT Overview Tech Specs Knowledgebase PST Penetration Probe (5m Lead)The RFPX500 PST Penetration Probe is for use with RF wireless monitoring systems. The probe is connected to a 5.0m lead.The RFPX500 PST Penetration Probe is fitted with a 6-Pin Lumberg connector with locking screw, to provide a strong and secure probe-to-instrument connection with better prevention of liquid ingress.Penetration Probes ExplainedAll of the Penetration Probes for RF500 Wireless Monitoring System are designed to be robust, yet at the same time unobtrusive. That is why the standard Penetration Probes for RF500 do not come with probe handles.The Penetration Probes for RF500 Wireless Monitoring System, come in the form of a stainless steel pointed shaft, as shown below.The Penetration Probes are designed to be inserted into samples so that the temperature recorded will accurately represent the sample. However, unlike the Air Probes, the Penetration Probes potentially are destructive to the sample, i.e. it cannot be used as intended. Or alternatively, the sample is simply representative of the true item, e.g. A Glycol filled Blood Bag. The whole purpose of all RF500 Penetration Probe design is to ensure that you do not receive false alarms.All RF500 System Penetration Probes are fitted with a 6-Pin Lumberg Connector and a stainless steel Pointed Penetration End end, as shown below.

This problem may also be prevented by keeping the instrument clean when in use.If this does not work, you will need to return your instrument for service. 20th April 2015 General Care of Temperature ProbesGeneral Care of Temperature ProbesThe Probe is where most of the action with any Thermometer takes place. Almost every operation requires a Probe reading. The Probe should be treated with care in order to ensure best functioning and long life.We would recommend that you always have a spare, properly functioning Probe on hand, just in case the primary Probe breaks, or appears to be reading incorrectly.You should not stretch the coiled cable of any Probe, to reach an item to be measured. We would recommend instead that you ALWAYS move BOTH the Probe and the Thermometer, toward the food to be measured. This will help avoid unnecessary stress on the wires inside the Probe.You should not touch the coiled cable or Probe handle to hot surfaces, that might melt the protective coatings, which in turn could damage the Probe wires and render the Probe inoperable.You should not bend the tip of any Penetration Probe, as this too could break the wires and render the Probe inoperable. In general, Penetration Probes are designed for penetrating thawed food only and not for testing frozen food or containers or chipping ice.You should clean the Probe and wire coil with a clean damp cloth, being VERY careful not to pull or stretch the coil and damage the wires inside.
