| 1.Product Overview | ||||||||||||||||||||||||||||||||||
| The CD4 (B) toxic gas detector (hereinafter referred to as the detector) can simultaneously and continuously detect the concentrations of four gases: combustible gas, oxygen O2, carbon monoxide CO, hydrogen sulfide H2S, and can alarm for exceeding the limit. It has a new generation of mainstream appearance design, beautiful and durable, gas concentration calibration and other functions. The product has automatic storage and recording data function, can store 200 sets of data, real-time update and automatic coverage, new curve function, up and down keys to view historical curve changes, data transmission function, wired data upload. Time and date setting, using seat type charging, convenient and practical. The new generation CD4 (B) has a measuring device that uses an 8-bit microcontroller as the control unit, high-precision detection components, high sensitivity, fast response speed, and a wide temperature range color LCD screen for clear and reliable display. When the concentration of the gas to be tested in the environment reaches, exceeds or falls below the preset alarm value, the measuring device immediately emits sound and light to remind us to take timely safety measures and ensure the safety of life and property. | ||||||||||||||||||||||||||||||||||
