The OLC 10 and OLCT 10 are designed for the detection of combustible or toxic gases in tertiary applications (boiler plants, battery charging rooms, car parks, hospitals).
Two 10-s OLCs can be connected to one detection channel to monitor the same area, without additional junction boxes or wiring. Similarly, up to five 10-s OLCTs can be connected to one channel to detect CO, NO or NO2 in car parks.
The OLCT 10N is a digital detector compatible with the MX 32 and MX 43 controllers. A maximum of eight OLCT 10Ns can be connected to an MX 32 and thirty-two OLCT 10Ns to an MX 43.
Semi-automatic calibration with standard gas can be performed by one person without opening or adjusting the case.

• Pre-calibrated sensors
• Built-in relays
• optional HART communication protocol
The DG-7 gas detectors are easy to use and maintain and use a wide range of sensors.
The electrochemical sensors are certified intrinsically safe and can be replaced without disconnecting the detector. The DG-7, constructed of stainless steel and equipped with a bright display that changes color according to the status (alarm, fault, normal, preheating), is an industrial detector suitable for harsh environments.
• specifically designed for harsh environments and extreme conditions
• waterproof, corrosion and vibration proof
• one-person, non-intrusive calibration
The 700 series is designed for extreme environmental conditions. The case is made of stainless steel and the electronics are encapsulated in resin to protect them from the external environment.
It also features factory-calibrated “smart” detection sensors, which are recognized by the detector for easy replacement in the field.
