53 37, pH electrode with integrated PtIDrjO 53 55, ORP electrode, platinum
These are long-life electrodes. The open r/mob-dorr Ir-iril rater, rl if-, r r.orract between the reference electroIy re and the medium to be measured. Thanks to this contact, the classic problem of clogged cisphrayms dru a til rig of the past The reference electrolyte is a solid polymer where variations in concentration take place very slowly, so l:-at rhe référence po:e-:i;;l ren«in'> nv«iir,:ile icy p.
Advantages
,-¡■1 \ !c':yU' I :i!i■
Additional internal diaphragm which protects the reference element from contamination. These electrodes last a relatively-long time in relation to convent o.-ai eieci'ories r difficult media. Very competitively priced.
Model 53 37. with integrated ATC Pt1000 also allows sirriLllariL'Ous measurement of pH and temperature at the same point. Makes calibration easier.
Limitations
Rsoic a Tf.aiion cr the polymer w tlv ■ solutions with pH <2
- very clean, distilled and de-mineralised waters.
- temperatures above S0°C.
Mounting. See housings, pages 66 73 In immersion housings In 61, In 63 and In I In insertion housings In 76, In 77 and In 78 In flotation housings FL 60 and FL 69. In flow-through chamber CR 60.
