In　order　to　study　the　effects　of　water　sources　on　the　triple　point　temperature　of　water,　the　triple　point　of　water　(TPW)　cells　with　four　different　water　sources　are　fabricated　in　light　of　the　same　procedure.　Also,　the　comparative　experiments　among　these　cells　are　conducted.　The　comparison　results　show　that　the　realized　TPW　temperatures　by　means　of　these　cells　are　in　good　agreement　within　0.02　mK.　Consequently,　it　can　be　concluded　that　the　effects　of　water　sources　seem　very　small.
