The Icon Scientific Vapour Pressure Analyser from HMA Instrumentation measures the pressure exerted by vapour in equilibrium above a liquid at a specified temperature and vapour-liquid ratio. Vapour pressure is a measurement of volatility.
Vapour pressure measurement is applicable in gasoline, LNG condensate, crude oil and liquefied petroleum gas production. The Icon Scientific Vapour Pressure Analyser from HMA Instrumentation uses the piston expansion principle to measure vapour pressure, in line with the latest vapour pressure test methods.

The Icon Scientific Vapour Pressure Analyser from HMA Instrumentation can perform single or multiple expansions. While it normally operates at 37.8°C, and with a 4:1 liquid-to-vapour ratio, its measuring temperature and liquid-to-vapour ratios can be varied up to 60°C and 20:1. The liquid and vapour volumes are tracked by laser for unparalleled accuracy.

Features include:

Vapour pressure measured according to modern test methods: Results can still be correlated back to Reid Vapour Pressure by using published and accepted correlation factors.
Precise temperature control: Using a Peltier cooler and cartridge heater, the cell temperature is controlled accurately and measured for better repeatability.
Laser precise liquid-vapour ratio measurement: Provides superior repeatability.
Test-method adaptability: Variable piston expansion enables vapour pressure to be tested in accordance with various standard test methods.
