All inline, immersion & submersible sensor series except the 2X12 & 6X11 are suitable for immersion and submersible type installations since they come standard 4 each protective tines as the default configuration. It is recommended to also consider selecting a Waterproofing Option for Fully Submersible Assemblies. Inline, immersion & submersible sensor series are available in 2 each only protective tines configuration ("GRO") for ease of cleaning for process measurements where extensive buildup is common as well as the no protective tines configuration ("NG") for cases where this is desirable to minimize fouling build-up on the measuring tip (typically only used in conjunction with the low-profile thick-wall break-resistant parabolic style pH glass configurations).
  • Wrench flats feature is standard for 3/4"-1" MNPT series pH sensors and ORP sensors (6X52, 6X51, 6X31, 6X41) and knurls feature is standard for 3/4"-3/4" MNPT series pH sensors and ORP sensors (6X53, 6X54, 6X32, 6X42 and 2X12, 6X11, 6X13, 6X12) to allow for securing sensor into threaded 3/4" FNPT inline process connection or 3/4" FNPT and 1" FNPT immersion tube without damaging sensor body.
    • Care must be taken not to over-tighten any sensor to avoid damage during commissioning or insertion and removal from process for cleaning, recalibrating or replacement during maintenance. Consult ASTI factory for assistance to ensure best practice care and use.
  • Each standard sensor selection and/or special customized sensor design are based upon a thorough review of the customer supplied application information by senior in-house chemists to ensure that the best possible choice of available pH sensor or ORP sensor model and options is made at the lowest possible price configuration which is suitable for the intended process measurement & installation scheme.
  • pH sensors & ORP sensors are manufactured with sensor body housing materials of construction ranging from cost-effective Chlorinated-Polyvinyl-Chloride (CPVC) for simpler measurement requirements to rugged RADEL® (Poly-Phenyl-Sulfone, PPSU), KETASPIRE® (Poly-Ether-Ether-Ketone, PEEK) or RYTON® (Poly-Phenylene-Sulfone, PPS) to handle even the most difficult field process measurement applications.
  • Thick-wall break resistant low-profile parabolic pH glass element for slurry and viscous type process media extends service life for tough installations.
    • This type of rugged parabolic thick-wall, low-profile, break-resistant pH glass is now standard for all X3XX series pH sensors.
  • Novel extreme dehydration resistant reference technology option allows sensor to endure prolonged exposure to dryness as well as intermittent wet and dry operation conditions for batch applications and uncertain fluid levels

Inline, Immersion & Submersion pH Sensor & ORP Sensor Options

  • All 6X52/6X51/6X31/6X41 and 6X12/6X13/6X32/6X42/6X53/6X54 series pH sensors and ORP sensors are supplied standard (default) in the four (4) each protective tines ("GR") configuration. The number of protective tines can be reduced to the 2 each ("GRO") configuration or the guard feature removed altogether ("NG"). The reduction to 2 protective tines type guard (or else no guard at all) is sometimes desirable for ease of cleaning, particularly in heavy slurry and high viscous media process media applications.
    • No guard configuration is most typically used for sensors with break resistant parabolic pH glass element (X3XX series) or for ORP sensors (X8XX series)
  • All 6X11 series pH sensors and ORP sensors are supplied standard (default) in the without any protective tines (no guard) configuration. The number of protective tines can be increase to the two (2) each protective tines ("GRO") or four (4) each protective tines ("GR") configuration if desired. These options are typically invoked on the 6X11 sensor for immersion and submersible type installation use.
  • The 2X12 series pH sensors and ORP sensors are intended ONLY for 3/4" NPT inline installation only. Do not use these sensors for immersion or submersion style intallations.
  • Fast  temperature compensation response may be desired for some installations with variable temperature conditions (IotronTM ACCU-TEMPTM).
    • The ACCU-TEMPTM ("X") option is recommended for most inline installations for best temperature compensation as well as for immersion and submersible installations where the sensor will be frequently removed from service for cleaning and recalibration.
  • All inline and immersion sensors can have the waterproofing option added for submersible sensor installations.
  • All series pH sensors or ORP sensors may be mounted from rear using the 3/4" or 1" MNPT threads for immersion installations using a suitable mating insertion tube, standpipe or guide rod
  • Sensors employed for immersion of submersible style installations have some form of a protective tines (with guard) configuration to minimize possibility of accidental breakage during handling and field use.
  • The inline & immersion series pH sensors or ORP sensors can also be installed with a variable insertion depth into a process line or tank using a compression fitting only scheme (see link below)
  • Sensors with integral preamplifiers can be supplied with the rugged field ready Q7M/Q7F NEMA 6P rated quick disconnect snap connector system. See pictures shown below for visualization of this option.
