Surface water, seawater/water, and wastewater detection

1. Topic Content and Scope of Application

1.1 Topic Content This standard specifies the method of measuring water temperature using a water temperature gauge, a deep water thermometer, or an inverted thermometer. 1.2 Scope of Application This standard is applicable to the determination of well water, river water, lake and reservoir water, as well as seawater temperature. Principle 2: At the water sample collection site, a specialized mercury thermometer is used to directly measure and read the water temperature. 3 Instruments 3.1 Water Temperature Gauge: Suitable for measuring the surface temperature of water. The mercury thermometer is installed in a specially designed metal casing with a window hole for thermometer reading. The casing has a lifting ring at the upper end for tying the rope, and a metal cylinder with a hole is tightly screwed at the lower end of the casing to hold water. The ball of the water thermometer should be located in the center of the metal circle. The Hongzhi range is from 6 to+40 C, with a graduation value of 0.2 C
