KX9787 Special Duplex Air and Core Probe

The KX9787 Special Duplex Air and Core Probe is a duplex probe with a core (penetration) probe on channel one and a damped air probe on channel two.

KX9787 Special Duplex Air and Core Probe

The KX9787 Special Duplex Air and Core 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.

The KX9787 Special Duplex Air and Core Probe is designed so that  one probe measures a core temperature by being placed inside a receptacle that simulates a dummy load, whilst the second probe is designed for you to measure the air temperature.

For example, in a blood laboratory, the regulatory authorities stipulate that the ‘issue fridge’ or freezer being monitored, has to have an air and core measurement, so that it can be proved that the blood products being provided, are within the permitted range as set out in the guidelines. Issuing a blood product to a patient that has not been stored correctly, could have serious implications.

The KX9787 has a wide range of applications beyond the blood laboratory and has been implemented within the life sciences sector, to measure the temperature of simulated product growth in incubators and warming cabinets.

‘Damped’ Air Probes Explained

It is fair to say, that any probe that can measure temperature, could be used as an Air Probe, with varying degrees of success. However, Air Probes are specifically designed for this purpose and so have a higher degree of accuracy and response.

Air Probes are often designed to be very quick response with a low thermal mass. The sensor is designed to be as small as possible so that the air temperature is transferred to the probe with minimal temperature loss or gain to maintain a high degree of accuracy.

We supply a Damped Air Probe style for many of our air probeswhich comes in the form of a small stainless steel bullet shaped end, see picture.

This type of construction has two purposes;

  • It protects the sensor from physical damage
  • It slows the response of the probe down significantly

In certain scenarios, it is beneficial to have a slower response to changes in air temperature, hence having a Damped Air Probe. For example, when you place a probe inside a fridge or freezer, you probably don’t want an alarm going off every time someone opens the door.

The Damped Air Probes do a good job of reflecting the samples in a fridge.
