How Many Channels Does the ThermaViewer Have?
The ThermaViewer has two ports so that one
ThermaViewer can monitor two different areas.; It can monitor one refrigerator
and one freezer, or two freezers, or one incubator and one freezer, 2 rooms, etc,.....
Each port has one or two channels depending on the type of sensor being used. If you are monitoring temperature only each port has one channel. However, if you are monitoring both temperature and humidity you get both measurements from one sensor. This makes it look like the ThermaViewer is actually using four sensors. It only appears to be so because the same sensor tracks temperature and humidity.
It is generally not possible to mix different types of sensors on the same ThermaViewer. You could not, for example, have one digital temperature sensor and one K-Type thermocouple on the same ThermaViewer, or one thermistor and one thermocouple. There is one exception: You can use one thermistor and one thermistor/RH sensor on the same unit (since the RH sensor unit uses a thermistor).
If this gets confusing, please call and tell us what you need to monitor and we will recommend a configuration for you.
ThermaViewer can be used with several different types of temperature and temperature/RH sensors depending on what you need to monitor and the accuracy needed.
