YSI Membrane Kits

Replacement membrane caps and electrolyte for membrane dissolved oxygen sensors.

Price range: $125.00 through $135.00 ex GST

Product Information

Key Features

  • Genuine YSI replacement membrane caps for the membrane dissolved oxygen sensors used on Pro Series and EcoSense handhelds
  • Six screw-on caps per kit, with electrolyte — no tools needed and no downtime waiting on a service agent
  • Polyethylene and Teflon membranes give good durability and chemical resistance in both fresh water and seawater
  • 1.25 mil PE for the fastest response, 2.00 mil PE for longer membrane life, 1.00 mil Teflon for chemical resistance
  • Separate kits for polarographic and galvanic sensors — the two are not interchangeable
  • Screw-on design means a membrane change and recalibration takes minutes, not a bench session
  • Stocked in Australia by Fresh By Design for fast dispatch
  • Choosing your kit: match it to your sensor, not your meter — 5913 for a galvanic DO sensor; 5908 (1.25 mil PE) for a polarographic sensor as standard, 5909 (2.00 mil PE) if you want longer membrane life, or 5906 (1.00 mil Teflon) for chemically aggressive water.
