Temperature Sensor Specific is for the temperature measurement at some distance from the unit or in a harsh environment, such as salt water of fish tanks, oil burner, vaccine storages. Temperature Sensor Ambient is just for the ambient temperature. See full details by clicking on links for these sensors.
Please choose Temperature Sensor Specific and not the Temperature Sensor Ambient. Nevertheless, the term 'precisely' is relative when it comes to temperature. Accuracy is the same for both as you will see in their spec. With the Temperature Sensor Specific you will just be able to place the sensor in that particular point where you wish to know the temperature. You can find clarifications on this subject in the section 'I have a problem...' of this FAQ.
Absolutely! We provide solutions for that for many years. The best up-to-date option for remote vaccine storage temperature and power monitoring is our new Plug-and-Go iSocket with Temperature Sensor Specific. You can order both as a pack with a proper plan here.
You cannot go below -55C with iSocket temperature digital sensors, however you can monitor power interruptions to your cryostat and so you know that something bad happened. You do this outage monitoring by installing iSocket to any free wall socket that is on the same electrical circuit with your cryostat. For monitoring low temperatures inside cryostats you need PTC sensors and proper components cascade that can support such sensor, because such sensor is basically just a resistor. We use digital sensor and iSocket will only read that sensor directly. The lowest temperature of the sensors is -55C.
You can request the temperature anytime when the power is presented. When the power is failed the unit will sleep. There is a small battery inside the unit so you can't monitor the temperature all the time when no power. However there will be a software update in Q3-Q4 2021 where we will add a facility to monitoring the temperature in a smart way during power outages - you will be able to configure how often the unit should wake up to probe the temperature and thresholds against which it should probe it. When it breaks thresholds you will get a notification. This way the temperature can be monitored one or two days if wake up interval is reasonable (about every hour). Probably it will be longer, we don't know - we are testing this feature and it will be release in the future with no extra fee if you already have the sensor and essential temperature option in your plan.
You can turn on or turn off your air conditioning system remotely with iSocket only if your appliance has a plug. Most air conditioning systems are wired directly to an electric cabinet and have a remote controller to regulate the temperature. You cannot connect the remote controller of such an appliance to iSocket, but if the equipment has a plug you can connect this plug to the iSocket, and set up your air conditioning system to the desired temperature and shut it down (turn off the power supplied through the iSocket to the plug of the appliance). You can then switch it on remotely before arrival. Please note, this option might not be recommended by the manufacturer of the equipment. You do this at your own risk.
10 feet (3 meters) is the maximum length of our sensor cables. You can extend the cable using a good quality alarm cable. Remember that a longer cable raises the probability of a high voltage drop and wrong measurements. If you use it only to check the temperature and do not use it as a thermostat, then some deviation in measurements would probably not be a problem. It is very important to use quality cable and connectors, however. We check the manufacturing of our temperature sensors to ensure high standards for all their components. Despite the apparent simplicity of this component, it is the product of a series of important factors.
