| Q. | How do I know HIAC exceeds ISO 11171? |
| A. | Very few manufacturers actually comply with the full ISO 11171 calibration standard, but with HIAC you get full traceability to NIST certified reference standard particles and comprehensive calibration report proving your accuracy.

| Q. | I am confused by the number of liquid particle counting standards, how can I become more informed about liquid particle counters? |
| A. | The makers of the HIAC liquid particle counters offer all customers on-site or factory training, and technical support via phone or email to ensure you understand HIAC liquid particle counters and can apply them to your application. You can access technical support immediately by clicking on any of the "Contact Technical Support" links placed throughout www.particle.com or emailing techsupportgp@hach.com directly. |
| Q. | Is there support for installation and set-up of your HIAC laboratory or portable liquid particle counters? |
| A. | Yes - All HIAC particle counter customers can receive on-site services for liquid particle counter installation, set-up, and calibration services. |
| Q. | How will viscous and/or dark hydraulic oils affect liquid particle counts? |
| A. | Light obscuration sensors are very robust technologies and rarely impacted by the color or viscosity of any given oil. The particle count concentration of the sample is the primary application concern. HIAC liquid particle counters uniquely offer high concentration alarms to inform the users should concentration affect the sample. |
