Hiniker Nitro-Lert Anhydrous Ammonia Knife Monitor
February 8, 2018
Hiniker's Nitro-Lert Anhydrous Ammonia Knife Monitor detects blocked NH3 knives. The free-standing system features an in-cab bar graph display that constantly monitors each manifold outlet for variations in flow rate, providing audible and visual alerts to the operator whenever a knife or a manifold outlet is plugged or partially blocked.
The Nitro-Lert system does not interact or interfere with existing rate control systems. Sensors can be added to monitor up to 80 individual outlets.
