OHAUS ST400M portable multi parameter instrument from the United States
The ST400M portable multi parameter instrument has been launched with high standards.ST400MIntegrating multiple functions into one,Can measure indicators such as pH, conductivity, salinity, resistivity, temperature, etcCan be applied to the pH of samples such as environmental wastewater, surface water, seawater, etcField measurement of conductivity.ST400M,
Adopting rechargeable lithium batteries, supporting long-term uninterrupted use; LCD large screen display, making operation clear and intuitive; IP67 waterproof rating ensures * * measurement results can be obtained in any situationThe STARTER series of electrochemical productsSTARTER400 series portable watch
It is a waterproof instrument designed for field or on-site measurements.
The ST400 is a portable pH meter with a precision of 0.01 pH.
ST400M is a dual parameter portable instrument that combines a pH meter with 0.01 pH accuracy and a portable conductivity meter with 0.5 level accuracy. Both of the above instruments can be widely used in industrial enterprises, environmental monitoring, etc. Ohouse products have a simple user interface, easy operation, precise measurement, and reliable quality; Providing you with more cost-effective products is the consistent pursuit of Ohouse Company.
The ST400&ST400M has many unique designs, including IP67 waterproof and dustproof design, rechargeable lithium battery; Equipped with a large display screen, data storage, and the ability to indicate electrode status. You will find that during use
The OHAUS ST400M portable multi parameter instrument from the United States has more practical functional features, some of which include:
Storage of 500 sets of data for pH measurement and conductivity measurement;
Dot matrix LCD display screen for clearer display;
Multiple pH buffer groups, multiple conductivity standard points * optional, to meet your different needs;
Used in conjunction with Ohhaus IP67 pH and conductivity electrodes, it is truly waterproof and suitable for harsh environments.
*Only applicable to ST400M dual parameter instrument
