The PLC or HMI employed can either be customer supplied or else ASTI supplied as a part of a turn-key ready system ready for plug and play field commissioning right out of the box.
ASTI supplied HMI & PLC include options for advanced smart touchscreen controllers with full remote access suitable use in for Class I, Division II hazardous locations as well as Explosion-Proof controller suitable for use in hazardous Class I, Division I EX rated locations. Lower cost instrumentation options also exist for use in safe non-hazardous locations as well as blind installations if no local display is required.
Available in smart digital configurations for use with intelligent pH/ORP digital transmitters. Detailed information about this smart digital type configuration option can be found in the separate 3TX-HiQ digital pH/ORP measurement product webpage.
Back of sensor 3/4" MNPT and 1" MNPT threads can be sealed with waterproofing option for use in immersion or submersible type applications as well as for inline use. 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.

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.
