Note 1:
Note 2:
Regarding the flow rate for gas detectors, there are 2 types:
- Pump-Suction Type: Equipped with a built-in pump, with a flow rate of 600 mL/min. (Models: GD200, GD400, GD600)
- Diffusion Type: Not equipped with a built-in pump, with a flow rate of 300 mL/min. (Models: GD300, GD500, GD800)
If you require a customized flow rate, please let us know your specific requirements. We will evaluate whether customization is possible. A flow rate that is too high or too low can affect measurement accuracy, so we recommend using an appropriate flow rate for your application.
Flow rate only needs to be considered when sampling gas from pipelines. For measuring gas concentrations in normal ambient air, you do not need to consider the flow rate. To measure confined spaces such as pipelines, please get in touch with us and provide the detailed conditions of use.

Application

Tips:
Toxic gas detector is a kind of gas detector specially used to detect the concentration of various toxic gases. It belongs to a kind of electronic instrument and meter. In some mining industries, such toxic gases are often produced and discharged. To better protect the safety of our staff and prevent us from being poisoned by toxic gases, we need to use such toxic gas detectors for gas detection.
When using this type of toxic gas detector, the most common one is the portable toxic gas detector, because the portable gas detector can be carried with you, and can detect and monitor the concentration of various toxic gases around us at all times, as well as the concentration changes. When the surrounding toxic gas concentration exceeds the safety value we set, the gas detector will send out various alarm reminders, such as various light alarms, sound alarms and vibration alarm reminders, reminding us to evacuate the scene quickly or do corresponding measures in time.
