Voc Detector-EST-10- II -VOC Two-level Sound And Light Alarm
The EST-10- II -VOC volatile organic gas detector is a portable handheld gas concentration measurement instrument that uses a natural diffusion gas detection method. Designed and produced in accordance with relevant national standards, alarm design standards, etc., it adopts high-precision circuit design. The core uses original imported sensor chips, which have been secondary developed and calibrated by Wanyi Technology, with temperature compensation, signal amplification, and stability testing. The standard gas is mixed by using a professional gas mixing instrument After the core sensors are calibrated and the products meet the relevant national standards, they will be finally released from the factory and delivered to the users
Product features
1. External power supply: DC5V, built-in rechargeable battery. It can be charged simply by connecting to an external power source.
2. The LCD screen can display various parameters, making the data clear at a glance.
3. Conversion between ppm and mg/m³ units.
This instrument has the function of viewing the average values within 5 minutes and 15 minutes
5. Intelligent design, complete functions, built-in temperature compensation correction, zero adjustment and calibration are very convenient.
6. Two-level sound and light alarm, with two high-brightness leds to alert users when an alarm occurs.
7. CE certification, ISO9001 quality certification, ISO14001 environmental system certification, and national metrological certification can be passed.
8. An optional sampling pump is available for safe and stable measurement in enclosed Spaces.
