Glove box water probe cleaning (only for washable probes)
1) Reason: If the water probe is not cleaned for a long time, some dirt will adhere to the surface, affecting the detection.
2) Steps:
① Close the cycle and analyzer;
② Set the working pressure to +5 to + 8mbar;
③Remove the water probe and quickly blind the air outlet with a blind plate;
④Unscrew the metal protective cover on the front of the probe, wash it with deionized water, and then dry it with dust-free paper, then moisten the probe with dust-free paper dripped with cleaning fluid, and apply evenly;
⑤ Put it back in place, open the cycle, turn on the analyzer after 1 hour, and return to normal level after half an hour.
note:
After the water probe is cleaned, the glove box pressure is set to the original value, and the cycle is turned on but the analyzer is turned on again after 1 hour, because after the water probe is cleaned, the probe surface is cleaned with deionized water or 85% concentrated phosphoric acid wetting contains water Yes, if the analyzer is turned on prematurely, the water value will always be detected and displayed to exceed the standard.
