5.1 This guide describes stabilization criteria for recording field measurements of Temperature, DO, SC, and pH.

5.2 This guide describes the procedures used to calibrate and check meters to be used in the field to records these measurements and the procedures to be use in the field to obtain these data.

5.3 This guide describes quality assurance procedures to be followed when obtaining cross-sectional means of temperature, dissolved oxygen, specific electrical conductance, and pH of water flowing in open channels.

TABLE 1 Stabilization Criteria for Recording Field Measurements (1)Note 1—[±, plus or minus value shown; °C, degrees Celsius; ≤ less than or equal to values shown; μS/cm microsiemens at 25°C, gt;, greater than value shown; unit, standard pH unit; mg/L milligram per liter].

±0.2°C ±0.5°C

Specific Electrical Conductance: 8199;when ≤ 100 mS/cm 8199;when gt; 100 mS/cm

±58201;% ±58201;%

pH: 8199;Meter displays to 0.01

±0.1 unit

Dissolved oxygen: 8199;Amperometric method

±0.3 mg/L

5.4 Field measurement must accurately represent the water flowing in the open channel being measured. Methods need to be used that will result in an accurate representation of the mean of the parameter of interest. Procedures must be used that will take into consideration the variation in the parameter across the sections and with depth.
