SEAWARD

The Seaward H101/US measures insulation resistance from 25 kΩ to 350 MΩ. It provides a 1 mA test current and features a digital display. The unit is rated IP40 and carries a CAT II 300V safety rating. This model is part of Seaward's range of AC/DC HiPot testers, which also includes the H103/US, H104, and H400GB. The H400GB extends the measurement range to 0.01 MΩ to 50 GΩ for applications requiring higher resistance measurement. These instruments are used for insulation resistance testing on electrical equipment and installations.

The Seaward Solar Power Clamp (SKU 39N147) is a solar analyzer with an LCD display designed for measuring open-circuit voltage in photovoltaic systems. It does not include datalogging. The Seaward SS200R is a solar irradiance meter that measures irradiance from 100 W/m² minimum and includes datalogging capability. The SS200R also provides a compass bearing range of 0° to 360°. Both instruments are used in photovoltaic system testing, but they serve different measurement functions: the Solar Power Clamp focuses on voltage measurement, while the SS200R measures irradiance and bearing for site assessment and performance evaluation.

The Seaward Safecheck 8 is a general-purpose tool and appliance tester designed for testing power tools rated from 4 A to 25 A. It performs insulation resistance testing and measures leakage current up to 20 mA. The tester also covers a resistance range of 0.4 Ω to 20 Ω. It does not carry a CAT safety rating. This model is used in portable appliance testing programs to verify the electrical safety of tools and equipment. The Safecheck 8 is part of Seaward's range of appliance testers, which are used by maintenance teams and electrical contractors to comply with safety testing requirements.

The Seaward H400GB is an AC/DC HiPot tester with a measurement range of 0.01 MΩ to 50 GΩ. It features a digital display and a 1 mA test current. The H400GB carries a CAT II 300V safety rating. Unlike the H101/US, H103/US, H104, and H_LED models, which are rated IP40, the H400GB does not list an IP rating in the available specifications. The IP40 rating on the other models indicates protection against solid objects greater than 1 mm and no protection against water. Buyers should verify enclosure requirements for their specific environment when selecting a model.

Seaward solar analyzers, such as the Solar Power Clamp (SKU 39N147), are used for measuring open-circuit voltage in photovoltaic systems. The SS200R solar irradiance meter measures irradiance from 100 W/m² minimum and includes datalogging and a compass bearing range of 0° to 360°. These instruments support photovoltaic system testing during installation, commissioning, and maintenance. The Solar Power Clamp verifies string voltages, while the SS200R assesses irradiance and orientation. Together, they provide data for performance evaluation and troubleshooting of solar arrays. Both are available from 3G Electric with specification details for procurement.

Seaward AC/DC HiPot testers such as the H101/US, H103/US, H104, and H_LED are rated IP40, which indicates protection against solid objects greater than 1 mm. They also carry a CAT II 300V safety rating, making them suitable for measurements on electrical circuits in category II environments. These instruments feature digital displays and provide a 1 mA test current. The H400GB offers a wider measurement range but does not list an IP rating. For field use, the IP40 rating provides limited protection against dust and no protection against water, so appropriate care should be taken in harsh environments.
