General Description

TN423LA(E)/ TN423LB(E)/ TN423LC(E) are the ultimate tools for temperature measurements.
It contains 2 most reliable temperature sensors:
2) Non-contact Micro Machineing Thermopile
2) K-type thermocouple socket

Such an arrangement can fulfill most of temperature measurement requirements:
Use the Non-contact for instant; not-reachable situation.
Use the thermocouple for high precision; non-surface situation.

Templorer also come with an ultra long battery life (8days for Alkaline battery), no 9V battery,
It use the most affordable and available AAA size battery.

Learn Emissivity with the Templorer:
Emissivity is a difficult concept for general user to catch.
But, with Templorer, it's easy to get, just use the contact thermometer to get the true temperature,
Then use the Non-contact to get the surface temperature, Adjust the Emissivity until they are the same.
Next time, use the correct Emissivity for that object. No more guess work, no more looking up on Emissivity Table.
