Instrument Introduction:
02111-1 PoreMaster-60 Fully Automatic Mercury Pressure Tester
Form a complete system with vacuum pump, software, sample tank, and all standard accessories
The host includes:
17024 Pressure Sensor -0-50PSIA
17025 Pressure Sensor -0-1500PSIA
17023 pressure sensor -0-60000, PSIA
01098 Oil filtration circulation system

- Hole diameter range: 1080~0.003 micrometers
Continuous or stepwise pressurization from vacuum to 60000 psi
- One high-voltage sample analysis and two low-voltage stations
Fully automatic computer-controlled two low-voltage stations can simultaneously charge mercury into the sample pool
- Can measure the total pore volume, pore volume distribution, pore surface area and its distribution,
Pore distribution and surface or particle density
Step by step and continuous pressure generation methods have the greatest flexibility
- Highest resolution mercury injection/discharge and sawtooth chart
- * 1500psi pressure sensor standard can achieve maximum resolution at the low end of the high pressure range
RS232 interface for multitasking PC control and data acquisition
User programmatic balancing time and balancing rate
- Autospeed automatic control system, used to adjust the pressure change rate according to the characteristics of sample injection/discharge
Windows software is used for automatic data collection, table and graphic report generation, and file management
- Perfect desktop design

Operational characteristics/indicators:
- Programmed sample pool vacuum extraction time
Programmed pool vacuum pumping rate
- Automatic mercury level control in low-voltage stations
- Users can choose to automatically backfill mercury in the sample pool
Automatically transfer hydraulic oil to the high-pressure chamber
The automatic high-pressure solenoid valve allows for automatic exhaust of the high-pressure chamber
- Superstatic operation in all pressurized/depressurized states
- Software based calibration
High pressure sensor calibration requires neither external pressure nor a vacuum gauge
- Integrated analysis setup, real-time data collection, data processing, and report generation
- Automatic calibration of sample pool
All instrument operations can be manually performed through a PC
Safety features/indicators:
- Built in cold trap to prevent mercury vapor from entering the vacuum pump and laboratory
The venting tool can ensure safe ventilation of PoreMaster
- High/low voltage limit switch
The software limits the maximum pressure input to 60000psi
- Special heat treated steel for high-pressure systems (ASTM A-564-95, ISO9001)
- High voltage cut-off disc
- Automatic overvoltage protection for circuits
Manual emergency stop: takes priority over automatic operation
The software interrupt function can safely return to atmospheric pressure state
Low pressure relief valve
Double safety internal locking: The low voltage station cannot be operated when the sample pool cover is not locked tightly
The unique sample pool tilt system can help completely drain residual mercury and prevent potential mercury splashing
Sealed low-pressure infusion to prevent direct exposure of the operator to mercury
- * Additional removable cold trap, located below the sample pool, to prevent contamination caused by any sudden mercury splashing
