Introduction
There's not much to say as to why we chose to review this product. We saw it advertised, it looked sort of cool and so we bought it. What is the Typhur Sync? It's what has become to be known in the cooking world as a "truly wireless" meat thermometer. If you aren't familiar with the term or concept of a truly wireless meat thermometer, let's take a quick look at what these truly wireless probes are.

The first truly wireless meat thermometers were the MEATER line of products. They had no wires between the probe that is stuck into the meat inside of a cooker and the device outside the cooker that displays the temperature information. How did these probes accomplish this? By using Bluetooth to communicate between the temperature probe in a cooker and a smart phone or tablet running an App outside the cooker.

And you further ask, how did they do this without burning up the electronics? Oh, they were very clever, they were. By enclosing all the temperature-sensitive components inside the portion of the probe which is stuck into the meat, that's how. That portion of the probe will never get much above the temperature of the meat, so neither will the electronics. The rest of the electronics that make up these probes, which can tolerate the higher temperature of a cooker, reside higher up in the shaft of the probe in the portion which is exposed to the high heat of the cooker.

So what does this mean for cooking meat? Well, no more wires, obviously. No more kinked wires. No more fried wires. And imagine what this could mean for users with rotisseries: no more opening the cooker, stopping the rotisserie and using a handheld thermometer to check the temperature of the meat.

Now that you know what a truly wireless meat thermometer is, let's take a look at the Typhur Sync to see how it performs.

NUGGET ALERT: With this review, we continue using our latest feature, the "Nugget Alert". These are nuggets of information about the product that you might wish to pay particular attention to because of their importance.

A Photo Tour of the Typhur Sync Base And Probes
So now let's take a look at the Typhur Sync base unit and probes. The photo on the left shows the front of the base unit with the base unit powered on. When it is powered off, the display is all black except for the faint arrow and circle buttons. The photo in the center shows the back of base unit and you can see how the probes slide into the base unit for storage. We have also circled the opening in the base unit for the speaker. Finally, the photo on the right shows the built-in stand.

NUGGET ALERT: Although the two probes and the two slots on the base unit are marked 1 and 2, the base unit doesn't know or care which probe is inserted into which slot.

Next, we have a few more views of the base. On the left, we see a side view of the base unit showing the USB-C charging port. In the center, a top view shows the two probes and how they slide into the base unit for storage and charging. Finally on the right, we show you another back view with one probe removed. This reveals the electrodes used for charging the probes.

Now let's take a look at the temperature probe:

As you can see, we have broken the probe down into thirds. The left third, or the top of the probe, contains the handle, the ambient temperature sensor (red dot) and the Bluetooth antenna. The middle third shows the "minimum insertion line" which is your guide to ensuring you insert the probe deep enough into the meat to protect the temperature-sensitive electronics. And finally, the right third shows the tip of the probe which houses the five internal temperature sensors. The approximate locations are indicated by the red dots. We could find no explanation from Typhur as to why they are not equally spaced.

NUGGET ALERT: For most brands of truly wireless temperature probes, it has always been vital that the part of the probe which makes contact with the charger be kept squeaky clean so that it can make electrical contact. If you have trouble cleaning your probe with soap and water, some 400-grit sandpaper does a great job of cleaning the probe.

NUGGET ALERT: Quite a number of people have reported over the years that with at least one brand of temperature probe, when pulling the probe out of the meat, the shaft of the probe pulls apart from the handle. The probe tends to stick to the meat at the surface due to juices solidifying and forming a bond between the shaft and the meat. We won't be able to determine if that's a problem with the Typhur Sync, but you can avoid this possibility by always remembering to first push the probe a short distance into the meat to unstick the probe, then pull the probe out.

Multiple Meat Sensors
Typhur has chosen to put all of its additional sensors down in the end of the probe so as to try to find the coldest part of the meat and produce the most accurate reading. This means that there is still only one ambient sensor and it is in a fixed location in the handle of the probe. What this means is that the App doesn't know if the ambient reading is coming from two inches above the surface of the meat or ½-inch above the meat. You can at least try to insert the probe so that the ambient sensor is always the same distance above the surface of the meat so that you get consistent results and adjust accordingly.

Why do we point this out? Well, contrast Typhur's decision to put all the extra sensors down at the end of probe with the Combustion Predictive Thermometer's placement of sensors equally-spaced along the length of the probe:

Combustion uses the extra sensors as well as the placement of the sensors to determine both the location of the coldest part of the meat as well as the location of the surface of the meat. Thus Combustion can do a better job of predicting the finish time of our cooks.

The Base Unit Display and Controls
The Typhur Sync base unit has a 2.4" TFT LCD display with Touch Capacitive Control. Of course, that is the diagonal measurement of the display. The measurements of the display are 1-15/16" x 1-7/16". Here is a photo of the display with the Touch Capacitive (touch sensitive) section highlighted with the red box:

And here is a diagram of the display with all the various elements identified:

Resetting The Base Unit
