IQT Lab Model

The Laboratory Model (LM) version of the IQT is ideally suited for those interested in a basic ignition delay testing instrument. The LM model benefits from the standard High Precision Fuel Injection System (HP-FIS), but does not include the automation and precision features of the TALM model. As the pioneer IQT model, the IQT-LM has delivered proven performance to many global users since its release in 1998.

The IQT is the specified equipment for testing fuels according to:

ASTM D6890: Standard Test Method for Determination of Ignition Delay and Derived Cetane Number (DCN) of Diesel Fuel Oils by Combustion in a Constant Volume Chamber.

EN 15195 (IP 498): Liquid petroleum products – Determination of ignition delay and derived cetane number (DCN) of middle distillate fuels by combustion in a constant volume chamber.

ASTM D6751: Standard Specification for Biodiesel Fuel Blend Stock (B100) for Middle Distillate Fuels

Each IQT system is supplied with a Windows 10 PC running the IQT TALM K2 software. The user interface allows improved high visibility test monitoring for viewing from anywhere in a lab environment, with the provided monitor display.

The IQT features a fully integrated data backup system which automatically backs up the entire computer system to an internal backup drive. The system’s primary drive features RAID 1 redundancy which ensures that should the computer ever have a disk drive failure, it can continue operating and the failed drive can be easily replaced.

• The TALM K2 software, provides highly visible test monitoring for view at a glance assessment
• Automated calibration (recommended for use with the Extra-Large (95 mL, stainless steel) Fuel Reservoir Assembly)
• Consistent with fuel specification test methods
• Automated test procedure, quiet operation and easy to operate
• Short test time (approximately 17 minutes), high productivity
• Enhanced productivity can still be achieved with the K9 self-sealing reservoirs and cleaning/filling station which permits multiple fuel samples to be prepared for testing ahead of time through use of multiple fuel reservoirs
• Can be used with either the TALM-K7 electronic pressure regulator system (K1 is not needed) or the mechanical pressure panel

• Sensitive to cetane improver additives and small fuel quality variations
• Can measure high levels of cetane improver (3000 ppm+ 2EHN) with no negative carryover effects
• Proven ability to test highly paraffinic fuels from synthesis or hydro-treatment
• Small sample size (less than 100 mL)
• High level of reliability, rugged system, low operating and maintenance costs
• Easy access for maintenance
• Safety track record established over many years
• Proven testing capability for B100 and other biodiesel fuels from many different sources
