Setup
Select the manufacturer and model of the detector you would like to compare. Some models may have multiple configurations. In this case, select the configuration that best suits your needs. If you do not see a particular manufacturer or model listed, please contact Brasch Environmental Technologies.
Note that the Brasch model displayed is the closest detector based on matching technical specifications. This model may or may not meet the specific requirements of a project. Be sure to check alternate configurations of the model for best results.
Product Details
Sensor Life is the expected duration for which the sensor will last. Actual life is heavily dependent on operating environments and can be longer or shorter than the listed value. Proper care and appropriate recalibration will ensure the longest possible lifespan.
Max. No. of Sensors is the most sensors that can be connected to a particular model. In some configurations, that model is already equipped with as many sensors as it can handle. In others, additional sensors can be added at a later time.
Detection Range is the concentration of target gas that the model is capable of measuring. This will be in parts per million (PPM), percent lower explosive limit (% LEL), or percent volume by volume (% v/v).
No. of Relays is the total number of relays that are in the detector. These may be used for actuating ventilation systems or for connecting external alarm/warning equipment.
Relays specifies the type of relays included in the detector. If different relays are present, quantities of each will be listed.
Relay Activiation Options lists the setpoints at which the detector can be configured to open/close its relays.
Fan Delay Options lists the delay time between reaching a certain level of gas and closing the associated relay.
Concentration Display shows what type of visual gas concentration indication is present on the detector. Most detectors also include some form of output that can be monitored to display the concentration elsewhere. This does not include LEDs that indicate alarm stage or relay activation.
Input Voltage is the power required to run the detector. Some detectors list the nominal input voltage while others list a range. Many models come in both low and high voltage variations.
Output Signal lists the types of signals output by the detector. These signals can be analog, digital, or both depending on the detector.
Enclosure Rating is the durability of the detector housing. Some detectors have multiple enclosure options while others are rated to multiple standards.
Compliance includes any standards with which the detector complies. This excludes any certifications for the detector enclosure that are already listed above.
