ST400M portable multi parameter instrument

Durable and waterproof portable multi parameter instrument is an ideal choice for on-site testing!

● IP67Waterproof grade, suitable for use in humid environmentsThe IP67 waterproof casing and IP67 waterproof electrodes make the ST400M an ideal portable multi parameter instrument that can be used for a long time in any testing environment.

Rechargeable lithium battery reduces downtimeRechargeable lithium batteries can support 40 hours of uninterrupted use and can be charged over 300 times, eliminating the need for frequent battery replacement.
The LCD screen displays clear and intuitive information, and is easy to operateThe ST400M software displays information that is intuitive and easy to understand, guiding users to operate with ease. All information during the testing process, including electrode condition, is clearly displayed on the LCD screen.
The instrument has a large capacity storage function, throughUSBTransferring data is simple and easy to operateThe ST400M can store up to 1000 test results. If stored
The storage result exceeds the upper limit. By connecting to the computer through a micro USB interface, the data can be quickly transferred to the laptop, ensuring that the user's test data is saved every time.
