Portable Micro Manometer – Thermometer for Pitot Tubes

The HD2114P.0 and HD2114P.2, HD2134P.0 and HD2134P.2 are portable micromanometers for Pitot tubes with large LCD display. They are used to perform measurements in air conditioning, heating and ventilation.

They measure the differential pressure measured by Pitot tube connected to the inputs of the instrument and achieve the speed and air flow in ducts or vents; also measure temperature with thermocouple K probe.

The instruments can be used as thermometers and can be employed with any kind of thermocouple K sensor if a standard miniature connector is used.

The HD2114P.2 and HD2134P.2 instruments are dataloggers. They store up to 36,000 samples which can be transferred from the instrument to a PC connected via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be configured using the menu. They are also equipped with an RS232C serial port which can transfer in real time the acquired measurements to a PC or to a portable printer.

The Max, Min and Avg function calculates the maximum, minimum or average values. Other functions include: the relative measurement REL, the HOLD function, and the automatic turning off which can also be excluded.  The instruments have IP67 protection degree.



Stainless steel Pitot tubes to measure air speed and temperature, for models provided with ‘K’ thermocouple, equipped with silicon tube with 6mm external diam., 4mm internal diam. and length 2m. PW cable has to be ordered separately.
