They are portable instruments with a large LCD display, they measure the absolute, relative and differential pressure.
The Max, Min, and Avg function calculates the maximum, minimum, and average values. The Peak function, which can be activated with the external probes connected to the PP471 module, detects the presence of pressure peaks. Other functions are: the relative measurement REL, the HOLD function and the automatic shutdown excludable. The instruments have IP67 degree of protection.
To measure the pressure, an internal module of differential type is used with respect to the fixed-scale bottom atmosphere. With the PP471 electronic module, which functions as an interface, the instrument can measure with all Delta Ohm probes of the TP704 and TP705 series.
