KD-12

kd12smallKD-12 is an ATEX certified gas detector that offers a reliable, cost effective, robust and environmentally friendly solution for fixed gas detection and monitoring of hazardous environments. Sensor options include hot-wire, electrochemical cell, galvanic cell, catalytic combustion, thermal conductivity and infrared technology depending on the application requirements. The detector can be used as it is in its simplicity since there is a display on the device that indicates both the gas concentration and alarms. It is also possible to connect a flash or a sound alarm directly via the 4-20mA output. Even for large systems with over 100 sensors with advanced control of ventilation, safety, shutdowns of equipment and gases KD-12 is a safe and cost effective alternative.

PROPERTIES:

• Large and clear LED display with an alarm indicator that also shows the gas concertation level
• Easy to maintain
• Rugged and lightweight with a weight of just 1.2kg
