Topcon CT-80 non-contact Tonometer

Defect: No air is produced from nozzle upon trigger fire.

The internal pump has failed, is clogged, or is dirty- preventing fluid movement of the pump to force air through the nozzle.

Attempt air-check procedures five times consecutively. If problem persists, the pump will most likely need to be replaced.

If above solution does not resolve defect, the device will most likely require service or repair.
