The Starter 400M multi-parameter portable water analysis meters offered by OHAUS are durable, battery-operated, waterproof units optimized for field-testing.
The rugged and lightweight units with waterproof housing are suitable for testing TDS, pH, resistivity, salinity, and conductivity in wet settings. Several hours of trouble-free testing in the field are ensured by a rechargeable lithium battery.
An easy-to-view liquid crystal display (LCD) and intuitive software enable easy operation, and an integrated USB port allows data to be transferred easily.
Features of the Starter 400M pH and Conductivity Portable Meters

The Starter 400M meters are designed with IP67 waterproof housing, and include IP67 probes and a rubber cover. Thus, the meters are suitable for extended use in any field setting.

A rechargeable lithium battery offers 40 hours of continuous operation, and over 300 charge cycles. This means batteries do not have to be changed frequently.

The ST400M meters include intuitive software that guides users through the operation. The large LCD clearly displays all the required data (for example, electrode condition) to run the tests effectively.
