What presentation formats does the data statistics and analysis function support?

It supports curve trend charts, pie charts and qualification rate statistics to intuitively display hygiene conditions.

Data can be uploaded to a platform for long-term analysis to assist management decisions.

What are the advantages of rechargeable lithium batteries over dry cell batteries?

Rechargeable lithium batteries require no replacement, offer long battery life, low cost and environmental friendliness.

With a large 3000mAh capacity and 6-month standby time, they are more convenient and economical than dry batteries for long-term outdoor detection.

Operation Questions

How to control the smearing area and force during sampling?

Smear evenly over a 5cm×5cm area with moderate force to ensure sufficient sampling, avoiding excessive force that damages surfaces or insufficient force leading to inadequate sampling.

What causes high detection results and how to solve them?

Causes include sampling contamination, invalid swabs, uncalibrated equipment and environmental interference.

Solutions: standardize sampling, replace consumables, calibrate the device, adjust the environment and retest.

How to set upper and lower limits for different scenarios?

Enter the settings interface, input standard limits for the scenario, save and apply automatically.

Limits for food, medical treatment and water quality vary and can be switched with one click.

What are the steps to view data on mobile devices?

Turn on Bluetooth or WIFI, connect to the device, enter the data interface, upload with one click, and view, share or export data in real time on a mobile phone.

What precautions should be taken for temporary storage of the detector after detection?

Clean the detection hole, turn off the power, place in a dry and ventilated area, avoid moisture, high temperature and heavy pressure to prevent damage.

How to ensure standardized operation when multiple people share the device?

Provide unified training, post operation procedures, set standard parameters, and regularly check data to avoid misoperation.

Maintenance Questions

What is the difference between daily maintenance and regular maintenance?

Daily maintenance includes cleaning, charging and inspection; regular maintenance includes weekly calibration, monthly cleaning and annual comprehensive maintenance, providing dual protection for equipment performance.

What emergency measures should be taken if the device gets wet?

Turn off the power immediately, dry the surface, place in a dry and ventilated area, do not turn on the device, and contact after-sales service for maintenance to avoid circuit burnout.
