ranges in order to maximize measurement accuracy and resolution. In addition, some
thermistor probes are constructed to accommodate special environmental or application
conditions.
There are six different types of ET Series Temperature Probes available that cover a wide
range of operation.
· ET-016 General Purpose Temperature Probe is best suited for general purpose
temperature measurements centered on ambient room temperature.
· ET-004 Low Temperature Probe is ideal for sub-zero temperature measurements and
consists of a handle with a stainless steel penetration probe (it can be used, among
other applications, to monitor semi-solid frozen foods).
· ET-081 High Temperature Probe is best suited for higher temperature centered on
77°C (170°F).
· ET-086 Oven Temperature Probe is designed for even higher measurement centered
on 150°C (300°F).
· ET-016-STP is used to monitor skin temperature on human and animals.
· ET-016-SMP is used to measure pipe surface temperature. It wraps around any pipe
less than 2" in diameter.
If your needs for temperature measurement do not quite fit the ET series profile, you may
consider using a different type of probe. The
how you can work with other commercially-available thermistor probes from many different
suppliers.

Setup and Use

ET series thermistor probes are easy to use and setup with your loggers. To make a probe
work with your particular logger, follow the instructions for using remote thermistor probes in
the chapter that deals with your SmartReader Plus model. After connecting your thermistor,
make sure:
· the proper temperature equation is loaded for each enabled channel. If you do not use the
correct equation, you will end up producing misleading readings.
· to check the operation of your external probes before heading out in the field by viewing the
Realtime values in TrendReader software.
