See Accessories section for patch cable ordering codes. 05, 10, 15, 25, 50 fixed cable length (in meters) Ordering Information Each probe is supplied with HI764113-1 DO Smart Cap with O‑ring, protective cap, calibration beaker, sachet with silicone grease, syringe, and quick reference guide with probe quality certificate. See compatible probe extension cables on page page 15.58, see addtional mounting accessories on page 15.33, see probe holders on page 15.138 and 15.134. Smart Cap stores factory calibration coefficients. The domed surface helps repel surface bubbles and provides increased luminophore surface area for better measurement sensitivity.
