GENERAL

 

CHARACTERISTICS 

 

The Manometer - Thermometer Model HD2304.0 is a portable instrument that allows measurement 
of 

absolute, relative 

and

 differential pressure

, and 

temperature

 

The 

PP471

 electronic module is used to measure the pressure. The module works as an interface 

between the instrument and the TP704 and TP705 series Delta Ohm probes.  

 

The 

temperature

  is  detected  using  immersion,  penetration,  contact  or  air  Pt100  probes  with 

SICRAM module, or direct 4 wire Pt100 probes. 

 

The  probes  are  fitted  with  the  SICRAM 

automatic  detection

  module,  with  the  factory  calibration 

settings already being memorized inside. 
 
The units of measurement for the measurable quantities are:  

 

 

Pa (Pascal) 

 

hPa (hectopascal) 

 

kPa (kilopascal) 

 

mbar (millibar) 

 

bar (bar) 

 

atm (atmosphere) 

 

mmHg (millimeter of mercury) 

 

mmH

2

O (millimeter of water) 

 

kgf/cm² (kilogram-force/square centimeter) 

 

PSI 

 

inchHg (inch of mercury) 

 

°C/°F 

 

Using  the  MAX,  MIN  and  AVG  function  of  this  instrument  respectively  obtains  the  maximum, 
minimum or average values. 
 
Other available functions are:  

 

the relative measurement REL; 

 

the HOLD function; 

 

the automatic turning off which can also be disabled. 

 
For further details see chapter 2.
