Features
TesterMeter-JT2802 built-in high-sensitivity temperature, humidity, PM2.5, CO2, etc. (TVOC, formaldehyde, CO sensors can be expanded according to needs) a variety of air quality and environmental monitoring sensors, internal gas path design is reasonable, no directional requirements to ensure the accuracy of the test sex. The built-in circuit adopts high-precision AD chip module with fast response and standard RS485 MODBUS protocol output, which is convenient for secondary development. The appearance design is beautiful and generous, and the design of the multi-opening shape panel is novel, and it has a good environment integration effect. Color LED warning display, brightness can be adjusted by touch to adapt to the environment. There are two installation methods on the table top and wall mounting, suitable for any place where long-term online monitoring is required. |
