Recent events in the meat industry heighten the need for:

• One shot stunning
• Verification that the stunning devices are working properly
• Elimination of risk materials in the blood stream

Jarvis model USSS-1 (penetrating) and USSS-2A (non-penetrating) stunners render the animals insensible to pain in one shot.

Jarvis stunner testers, the AST series, verify the proper operation of the stunners.

Jarvis model USSS-2A (non-penetrating) does not force brain matter into the blood stream.
