TEC Services currently calibrates and services all TEC Services’ current model photometers:

• PH-4
• PH-5
• PH-7

We have extensive knowledge of the above-mentioned photometers and will provide prompt and efficient service. The turnaround time for standard calibrations has been 3 days or less since we began calibrating photometers over 25 years ago.  The industry standards recommend calibration of aerosol photometers on a yearly basis provided the units were handled properly during the 12-month period.  TEC Services, Inc. provides NIST Traceability on all models manufactured in the USA.

TEC Services also now calibrates our AG-E3 Aerosol Generator Pressure Gauges
