HumiPyc ™  model 1 Gas Pycnometer (helium, nitrogen, air) / Density and Moisture
Analyzer (with temperature control from sub-ambient to 50 C)
A powerful research idea:
True density measurements at precise RH and temperature conditions (pressure from vacuum to 50
psi (345 kPa), temperature from sub ambient to 50C, and relative humidity 0-100%).
RH analysis in
the pressure and temperature range, sorption and kinetic data from multiple headspace extraction.
Designed especially for density measurements of fine powders and foams... learn more       

HumiPyc ™  model 2  a new model of enhanced gas pycnometer (helium, nitrogen, air) /
Density and Moisture Analyzer/ Filter Integrity Testing - Bubble Point and Pressure Decay Analyzer,
a member of
NEVA series; No Elutriation Volumetric Analysis

Design Advantages of HumiPyc Gas Pycnometers   model 1  and  model 2
V-GA™ Versatile Gravimetric Analyzer -  high capacity, modular design, robust
and fully automated gravimetric analyzer
for sorption/desorption, kinetics, and permeability studies at
a fraction of cost of other systems. Addition of a special cell allows measurement of  WVTR,  
pervaporation, and permeation rates ...

HumiSys ™ LF Relative Humidity Generator for low flow rates.
Designed for special applications (instrument specific) and OEM applications..... learn more  

HumiSys ™ HF  Relative Humidity Generator for high flow rates  is a
mass flow controller based, high flow (up to 50 L/min), high temperature, and multi-sensor relative
humidity generation system. Fast response, wide flow range, fully automatic and manual operation,
and easy integration with a larger analytical setup make it ideally suited as a valuable R&D tool for a
wide variety of applications requiring an accurate and stable source of water vapor. Modular and
"open architecture" design allows for customization to address high pressures operation and other
needs...

V-Gen™ Dew Point/RH Generator - auto/manual
Designed for easy interfacing with other equipment and can accept external sensors, like RTD, RH
probe, or Dew Point Analyzer for relative humidity measurements. Microcontroller board, ancillary
electronics, firmware software featuring simple command language and digital protocol for
transferring RH and temperature data from Rotronic HygroClip probes (16 bit resolution) are added to
model 1.
Recommended for fully automated  applications and calibrations purposes:
automatic operation via
sophisticated PC software for experiment design and control,  
any master controller can use the
command language to control the generator via serial port,
versions with up to 50 psig output pressure
available...

Especially designed for measurements of cement fineness where Blaine apparatus
according to ASTM C 204 – 07 method  is typically used.

Software allows calculation of surface area of powders (packed-beds) using
Carman-Kozeny equation.

True density, porosity, and gas permeability specific surface area of
powders can be measured by a single instrument.
Constant volume gas (air) permeameter option to HumiPyc,
Model 1 and Model 2 gas (helium) pycnometer.
