  • Page 44 The United States Pharmacopoeia Regulations establishes limits and calibration requirements for WFI (Water For Injection). The HI5321 meter supports conductivity measurements that are needed for off line measurements in a Stage 2 of the regulation. Stage 1 verification may be carried out in a container but the regulation requires an in‑line measurement.
  • Page 45 Stage 1 ‑ this is an in‑line test. The procedure follows: • Measure the temperature of the water and the absolute conductivity readings. The measurement must be an in‑line measurement. Results may be verified using a laboratory method. • The temperature should be rounded down to the nearest 5 °C.
  • Page 46 Stage 2 ‑ this is an off‑line test. To perform this test: • Store the water sample in an enclosed clean container that has been rinsed previously with water of the same quality. • Adjust the sample’s temperature to 25 °C and agitate the sample to ensure that it has equilibrated with ambient •...
