The LogTag is so simple to set up and use that you'll be an expert in no time. We have a full LogTag training program on our site.

Add a probe and leakproof vial for the ultimate vaccine monitor

The advantage of having a logger with a probe is that the probe can be placed into a non‑freezing liquid, such as glycol, to better mimic what a liquid vaccine is experiencing.

The graph produced by the immersed probe generally has shallower peaks and troughs.

No separate reader required

This logger can be placed into a standard LogTag Reader, but it also has a slot for a USB C cable that can connect it directly to your PC.

Who uses these LogTags?

This model of LogTag is extremely versatile.

Hospitals, pharmacies and medical centres use them to monitor vaccine fridges.

Food manufacturers and distributors use them to monitor food fridges and freezers.

Manufacturers who ship temperature sensitive products use them to monitor their shipments.

Anyone monitoring liquid temperatures can use them by immersing the probe e.g. aquariums, HVAC cooling towers, bain maries.

Recording Indication State indicator “RECORDING”.
Download Time Typically less than 10 seconds for full memory (15,905 readings), depending on computer or readout device used.
Environmental IP61 (when vertically mounted or hung).
Power Source 3V CR2032 (LiMnO2) coin cell battery, user replaceable.
Battery Life 1 year storage, followed by 1 year of operation with normal use (6 minute logging, statistics reviewed on the display no more than once daily for no longer than 30 seconds each time, download data monthly). NOTE: Continual activation of the audible alarm will reduce the working life of the battery. When an alarm is triggered, the alarm should be cleared and reset as soon as possible.

Certification options explained

If you need some form of certification about the accuracy of your logger, you have various options.

Certificate of Calibration

This is a free certificate that comes with every LogTag. You can access this certificate through the configuration page in LogTag Analyser.

Certificate of Accuracy

This paid certificate is from a laboratory that uses testing instruments that have been calibrated using NATA-traceable instruments.

NATA Certificate

This paid certificate is from a laboratory that has full NATA certification.

Pre-configuration

Before you can start using a new logger, you will need to configure it with all the settings appropriate to what you are logging.

This is not difficult, and we have instructions on how to do it on this website, but if you would prefer us to do it for you, that service is available at a small cost.

We can pre-configure your LogTag with our recommended settings for:

  • vaccine refrigerators (2° to 8°C),
  • food refrigerators (0° to 5°C), or
  • food freezers (-30° to -10°C).

This means, all you will need to do when you receive your LogTag, is press the Start button and place it in the environment to be monitored.

What is covered with our shipping insurance?

Our normal terms and conditions (like most businesses) is that you take possession the moment an order ships. If the order is lost or damaged in transit then, in theory, it’s your problem. In reality we will have a conversation and try to work out a good way to resolve the issue where we are both happy (or not too upset).

Shipping insurance is there to remove the drama. If an order is lost or damaged in transit, we will simply send out a replacement, and we will then deal with the courier directly to resolve the original problem.

Our shipping insurance also means that if an order is delayed beyond what is normal and reasonable then we will send you another shipment (stock levels permitting). Then you should receive one of them sooner, and when the second one arrives you simply Return To Sender.

How much is shipping insurance?

Shipping insurance is 5% of the cost of the goods.

Is it worth it? Practically we have had far less than 5% of shipments have problems. It is, however, what Australia Post and other couriers charge. Ultimately insurance is about peace of mind and less hassle when something does go wrong.

Shipping insurance as an option

Shipping insurance is offered as an option on all our web sites. You can select it at the checkout.

For large orders our staff may also ask if you would like shipping insurance.

If you would like shipping insurance on an order you are placing with us, just ask.

Mandatory shipping insurance

Unfortunately we have had a couple of large orders not make it and then the customer refused to pay. A friend suggested that the easy way to avoid the dispute is to insure any shipments where we have a significant risk.

If you would like an immediate line of credit (30 days to pay) and have the goods ship immediately (no credit check delays) and are purchasing over $500 then we will add shipping insurance to your order.

The shipping insurance can be waived if the order is between $500 and $2,000 and you provide us with a formal confirmation that you accept responsibility of the goods once they ship.

Alternatively you can prepay by direct deposit or credit card.

What is not covered?

If there is a clear proof of delivery to the shipping address provided then we class that as delivered. Unfortunately there are cases where it is lost somewhere between the loading dock or receptionist and ending up in your hands. But we also know that a photo of the bag against a generic grey background is not proof of delivery, it is just proof of existence! It needs to be a reasonable proof of delivery.

It also doesn’t cover the expectation of overnight delivery. For example, if we were to ship to Melbourne (we are in Sydney) then we would expect it to be delivered within about 3 days. Most of the time it is overnight, but there are enough floods and other issues that regularly cause minor delays. Sending a second order the next day tends to not fix the problem. If it is super urgent, talk to us about how we can minimise the risk.

For damage claims we ask that you contact us immediately and we will probably ask for photos or some proof. The shipping insurance doesn’t cover claims weeks later. We do have warranty covering our items, but it excludes physical damage (e.g. being dropped). If the goods are damaged in transit then please let us know ASAP so we can cover it under the shipping insurance.
