PN-50-O2 portable oxygen detector Introduction
PN-50-O2 portable oxygen detector is an intrinsically safe device for continuous detection of oxygen concentration. The instrument adopts sensor and microcontroller technology imported from world famous sensor manufacturers. It has fast response, high measurement accuracy, stability and duplication. Good performance, the performance of the whole machine is at the domestic leading level, the parameters can be customized by users, and the operation is simple. The internal use of large-capacity nickel-metal hydride rechargeable battery, long standby, reliable and beautiful; digital LCD backlight LCD screen display, clear and intuitive; instrument appearance using special high-strength ABS engineering plastic, stylish shape design, beautiful, feel good, durable. Feature
The whole machine is small in size, light in weight, waterproof, dustproof, explosion-proof, shockproof design
Safety Tip: Regular flashing lights, voice prompts
Large-capacity rechargeable lithium battery for continuous operation for a long time
Digital LCD backlight display, sound and light, vibration alarm function
Sensors use world-class imported brand electrochemical sensors
The upper and lower limit alarm values can be set arbitrarily, with zero point and target point calibration function, superior audio and audible alarm, ensuring the detection of dangerous gas concentration in a very unfavorable working environment and prompting the operator to prevent it.
Large screen number, character display, instantaneous value, peak value, minimum value display
