1. FEATURES

* Meter can cooperate optional pressure sensor with 2,

5, 10, 20, 50, 100, 200, 400 Bar, new calibration
procedures are not necessary when change the new
sensor .

* When change the new pressure sensor, just select

pressure type ( 2, 5, 10, 20, 50, 100, 200, 400 bar )
on the front panel button. The sensor type will
memorize into the circuit permanently.

* 10 kinds pressure units ( Bar, Psi, Kg/cm^2, mm Hg,

inch Hg, meter H20, inch H20, Atmosphere, hPA, kPA )
, unit select by push button on the front panel.

* Full line optional pressure sensors are available.
* Cooperate the external pressure sensor that its output

signal is 100 mV for full scale.

* Zero button on the front panel, easy adjust the zero

value of pressure sensor.

* Separate pressure sensor, easy for remote measurement.
* Microprocessor circuit assures maximum possible accuracy,

provides special functions and features,

* Real time SD memory card Datalogger, built-in Clock

and Calendar, sampling time can set from 1 sec to 8
hour 59 min. 59 sec.

* Manual datalogger is available, during execute the

manual datalogger function, it can set the different
location no. ( position 1 to position 99 ).

* Innovation and easy operation, computer is not need to

setup extra software, after execute datalogger, just take
away the SD card from the meter and plug in the SD card
into the computer, it can down load the all the measured
value with the time information ( year/month/date/
hour/minute/second ) to the Excel directly, the user can
make the further data or graphic analysis by themselves.
