According to different environments and test requirements, choosing the right VOC detector is a must for everyone engaged in safety and health work. The choice of different environments and different gas detector types. The manufacturer of the VOC detector summarizes the method of selecting the VOC detector in different environments.

1. stationary:

This is to use more detectors in industrial plants and production processes. Can be installed at specific detection points to detect specific gas leaks. The fixed detector usually includes a sensor and a transmission sensor head, which is installed on the test site as a whole, and the secondary instrument composed of circuit, power supply and display alarm equipment is installed in a safe place, so it is also easy to monitor. The test principle is the same as in the previous section, but it is more suitable in terms of process and technology to fix the continuous and long-term stability required for the test. In addition, it should be selected according to the type and concentration of the gas on site, and the specific gas should be installed in the area most likely to leak according to the specific gravity of the gas, such as the most effective height of the sensor.

second, portable:

portable instrument is easy to operate, small in size, and can be used as other production parts. The probe stick can measure temperature, humidity, CO, CO2, and calculate outdoor air ratio, dew point, wet bulb temperature, etc. On-screen prompts and step-by-step instructions will guide you through field operations, setup, and calibration. Insert the multi-function probe.

Use of the Voc tester in different environments.

1. closed places:

For example, reaction tanks, water tanks or containers, sewers or other underground pipelines, underground facilities, agricultural sealed grain silos, volumetric oil tanks, tunnels and other workplaces must be tested before people enter, and test outside the confined space.In this case, a multi-gas detector with a built-in sampling pump must be selected. The gas distribution and type of different parts (top, middle, bottom) of the sealed space are very different. Therefore, the complete sealed space gas detector must be a portable instrument with built-in inhalation function, which can detect dangerous gases in different spatial distributions such as gas and organic gas, and prevent hypoxia, overweight or small size without affecting the staff. jobs. Only in this way can the absolute safety of employees entering the confined space be ensured.

2. open place:

For example, the equipment can be used as an open workshop The safety alarm can also carry a diffuser gas detector to continuously, real-time and accurately display the concentration of toxic gases on site. Some of its new instruments are equipped with vibration alarm attachments to allow audible alarms to be heard in noisy environments, providing specific guidance for worker health and safety.
