pH/ORP Combination Sensor or pH Sensor
To prepare for installation:
1. Remove the shipping cap from the pH sensor.
2. If the shipping cap does not contain any liquid, pour HI70300 Storage solution into the
shipping cap.
3. Place it back on the sensor and soak for at least 30 minutes before use. If HI70300 Storage
solution is not available, pH 4.01 buffer may be used.
DO Sensor
To prepare for installation:
1. Sparingly lubricate the o-ring with a thin film of silicone grease. Use care to prevent grease from
contacting the optical window.
2. Remove the HI764113-1 Smart Cap from the container.
3. Align the cutout arrow on the Smart Cap with the matching guide on the HI7698494-5 sensor
body.
4. Slide and press the Smart Cap onto the sensor body until the cap snaps in place. Once the cap
is installed, it should not be removed unless a new cap is required.
5. Place the sensor in purified water to hydrate the Smart Cap before use.
