In terms of gas detection instrument selection, how to choose it, in the face of many users, they face a choice problem:
1. First, understand the purpose of your needs.
2. Know several types of meters, such as portable meters? Still fixed meters, they all have those differences.
3. The determination of the test range of the gas detector is generally determined by the standard of 150% of the test site concentration. Do not test very low concentrations over long distances, as this gives you accuracy
Not required. Do not use it over the range, as this will cause the gas detector sensor to be poisoned, and the overload will fail in advance.
4, portable gas detector, is a simple instrument to carry, hand-held. Stationary gas detector, mainly for the purpose of continuous 24-hour monitoring, can be effective
Link with other equipment, such as: exhaust equipment, once the harmful gas concentration exceeds the standard, you can start exhaust ventilation to achieve automatic work. System integration automatic
Monitoring equipment, this type of instrument has more functions, some also support the centralized monitoring and management of the gas control host, automatic inspection of multi-site gas detection
Meter concentration data.
5. Introduce your operating environment to the salesperson as much as possible, so as to accurately select a suitable instrument.
