How much does the McLane sampler weigh in water?

In summary, the conversation is about a person trying to design a buoyant housing for an electrical core that can be neutrally buoyant at desired depths. They are looking at the specifications of similar equipment online, and are confused about the weights provided for the core and pressure housing, as they are listed as "buoyant" instead of a specific weight. They seek clarification on whether the weight in water should be less and if the ballast tanks need to be filled for the measurement. The conversation ends with a request for the specific type and model of the equipment being discussed.

I am trying to design the housing for an electrical core so that it remains buoyant on the surface but can be neutrally buoyant at desired depths through ballast tanks.

I am trying to figure out what the core and housing may typically weigh through specifications online of ones already made.

However, the weight in air for core and pressure housing is 102.1kg buoyant while the weight in seawater for core and pressure housing is 150kg buoyant.

I've never seen buoyant after a weight like that and I'm a little confused if it just means it weighs 150 kg. Shouldn't the weight be less in the water? The only thing I can think of is that the ballast tanks of the housing must be open and filled with water for this measurement?

Can anyone help me understand this?

It's not clear to me, either.

Can you provide the links for this equipment which quotes these weights?

Thanks for the link.

However, the manufacturer has re-organized his web page somewhat. When I click on this link, it tells me that the page couldn't be found, and then directs me to a product library.

Could you specify exactly the type and model of the equipment you're trying to use?
