The testo 176 T4 temperature data logger can tell you at a glance if the temperature of the room or facility is within the prescribed thresholds. It can measure the temperature at up to four different sites simultaneously and has a super size memory that can save up to 2 000 000 readings. This gives you the freedom to read out the logger data at longer intervals, even when measuring cycles are shorter.

 

You will need at least one temperature sensor to use your logger. There is a wide selection of thermocouple sensors ranging from type K, T or J sensors to air, surface or probe sensors available.
