Starter 400M Multi-Parameter Meters are robust, lightweight, battery-operated units with
waterproof housing which makes them ideal for prolonged use in wet environments, and a rubber
protective case fit for field testing. A rechargeable lithium battery ensures hours of trouble-free testing
in the field. Intuitive software and an easy-to-view LCD allows for simple operation. A built-in USB port
enables easy data transfer.

• IP67 Waterproof Housing for Working in Wet Environments
Built with IP67 waterproof housing as well as a rubber cover and IP67 probes, the ST400/400M is
ideal for prolonged use in any field environment.

• Rechargeable Lithium Battery Ensures Less DowntimeRechargeable lithium battery provides 40 hours of uninterrupted use and more than 300 charge cycles—eliminating the need to change out batteries often.

• Easy to Operate with Intuitive Software and Information Displayed on the LCD
The ST400/400M features intuitive software which guides the user through operation. All
necessary information to run tests successfully such as electrode condition is displayed clearly
on the large LCD.

• Equipped with Large Storage Capacity and Ability to Transfer Data Easily Via USB
The ST400M has a large data storage capacity of 1000 records. If it exceeds capacity, data can be quickly transferred to a laptop via the micro-USB port, ensuring that users can retain every measurement.
