･ Clean room ･ Intertopus pressure in the hospital room, pressure inspection of combustion equipment / kitchen equipment ･ Negative pressure monitoring during asbestos removal work ･ Wind speed/air volume by pitot tube (~ 100 m/s) A differential pressure meter (manometer) is a measuring instrument that measures the difference in air pressure in two places. It is used to manage the air conditioning filter, the pressure difference in the clean room, the management of the negative pressure in the space. Testo differential pressure gauge has a handy type differential pressure gauge and a differentially set -up differential differential converter (differential pressure sensor). The compact, lightweight, easy -to -read screen with backlights, and a variety of TESTO differentiometers have long been selected in Japanese industries. ･ Selectable type: Measurement range/accuracy, memory with/no type, smartphone link type, permanent analog output type ･ Compact & lightweight, easy -to -read backlight digital differential pressure meter ･ Compatible with other parameters: Testo 440dp, Testo 400 has a built -in differential pressure sensor, and other parameters can be measured by attaching external sensors. Not only temperature but also pressure is one of the most important items in measurement. Testo has various high -performance pressure meters that can handle pressure -related measurement tasks, such as absolute pressure, differential pressure, and relative pressure. ･ Latest technology that enables efficient pressure measurement ･ Realize high -precision measurement regardless of the type of pressure ･ Equipped with a practical application and easily connects smartphones/tablets ･ Pressure measurement is possible quickly even in inconvenient places and difficulties to reach.
