The CALT 9 leakage tester has been designed and developed to measure leakage rates and give a detailed print-out of the test parameters and results. It is particularly suitable for measuring and calculating the leakage rate of double O-ring seals as fitted to packages for the transport of radioactive materials.
The CALT 9 is a portable instrument supplied in a robust case. The instrument is complete with all fittings including a reference volume to measure interspace volumes and a comprehensive instruction manual
All calculations are made by the computer. Full test details and results are printed out automatically at the end of the test (see over page).
The CALT 9 uses the pressure drop or pressurise method to give a quantitative result. The software automatically corrects for the change in dynamic viscosity of air which varies with temperature, and also converts the calculated leakage rate into Standardised Leakage Rate (SLR).
The CALT 9 is easy to operate. The internal computer displays a series of screen prompts which lead the operator through the leakage testing procedure in a manner that is easy to understand and follow.
The instrument has been designed to be flexible to meet user requirements. Bespoke software and/or hardware can be supplied to meet specific customer requirements.
The current version of the CALT software has five main options:
- Leakage Test - Pressure drop or Pressure Rise
- Measure Volume - The volume of the interspace must be known or measured before leakage testing can be carried out
- Print-Out - Print out the last test performed
- Measure volume
- Leakage test
- Combined measure volume and leakage test
- Gauge - Pressure/temperature gauge with or without a print-out
- Utilities:
- Password
- Calibration- Calibrate temperature & Pressure sensors
Print-out calibration history
Select primary or secondary calibration
- System set

Standard (ISO or ANSI)
Reference pressure
User name to appear on printout
- Date
Set system clock and date
- Portable and robust
- Quality Pressure Transducer
- Built-in printer
- User calibration
- Store calibration for spare transducers
- Calibration protected against power loss
- Flat front panel for easy contamination checking
- Temperature probe
- Built-in electric pressuring pump
- Comprehensive print-out
- Battery operated and portable
- External battery socket for charging during storage
- Supplied with 2cc reference volume
458 mm wide x 331 mm deep x 190 mm
11 kg
When a combined test for measuring volume and leakage is performed, the print-outs above are combined
with a single header and the common items printed only once.
The CALT 9 supersedes the CALT 8B with the introduction of a bespoke internal computer. The CALT 8B will
continue to be supported for spares, maintenance, calibration, software and hardware upgrades.
The CALT 9 hardware includes all the features of the CALT 8 with following new features:
- Interface autoswitch off
- Display sleep mode
- Li-ion battery pack
- External charger socket
- Comprehensive battery management LED’s
- Audible alarm
- A single battery to power the interface and printer and computer
- Low EM emissions and susceptibility
- Battery meter
The software is based on the CALT 8B version 2.42 software which includes:
- Easy reboot
- Safe/protected calibration
- Multi-calibration (which allows a spare transducer to be used)
- Combined measure volume and leakage test if required
- Last test print out from main menu
- Automatic parameter testing
If you are a CALT 8 user you will feel at home with the CALT 9, as the testing principles and the test procedure remain unchanged.
The CALT 9 builds on the experience of both the CALT 8 and CALT 5, incorporating features to meet users comments and generally to improve the instrument. Particularly noteworthy is the new Li-ion battery pack, this is robust and will take a lot of abuse with respect to over charging, over discharging and being left completely discharged for months. The battery compartment is accessible by removing front panel cover.
