• Best reference service lifetime in process industry through proprietary, novel, non-porous, cross-linked, conductive polymer technology; Available in double junction (standard) or triple junction (optional “TJ”) configuration. 
• Large surface area industrial grade PVC membrane for measurement of ammonium (NH4+), sodium (Na+), calcium (Ca2+), lithium (Li+), chloride (Cl-) nitrate (NO3-), nitrite (NO2-) and perchlorate (ClO4-) are solvent bound to PVC electrode for excellent mechanical integrity during long term use and for aggressive field process installations. 
• Fluoride (F-) ion selective sensing elements offers nearly no interfering ions and excellent linearity across avery wide range of use. Available for use in application from 0-12 pH ranges with AB 6100 model or 5.5 to 9.5 with AB 8100, AB 5100 or AB 6100H models. 
• Solid-state silver halide type ion sensing elements for measurement of chloride (Cl-), bromide (Br-), iodide (I-), cyanide (CN-) and silver (Ag+) are designed for use at elevated temperatures due to unique design and manufacturing scheme. Very large surface area and thick crystals allow for repeated repolishing as may be required for extended sensor service lifetime. 
• Available in no protective tines to minimize air bubbles for inline low-flow type installations. Also configuration are also offered in 2 each (“GRO”) or 4 each (“GR”) protective tine configurations recommended for immersion and submersible installations. 
• All ion selective sensors come standard with Pt1000 temperature compensation element. ACCU-TEMP option for fast temperature response is recommended for inline and sanitary installation styles were only the sensor tip is in contact with the process solution. 
• Selected optional features include ACCU-TEMP Fast TC (“X”) which is critical for accurate temperature compensation of inline measurements. The braid reinforced thick PVC jacketed blue preamplifier cable (“BL”) is available to best results in high noise environments or for installation where mechanical wear on cable may be a potential installation issue. 
• Ion selective sensors in base without integral preamplifier configuration can be used for installation up to 35 feet (~10 meters) maximum. The leads must be wired directly into the ISE transmitter with this configuration and cannot be bridged. ISE probes without preamplifier should be keep to a cable length of 20 feet (6 meters) whenever possible. For longer cable runs or to bridge the signal use the with integral preamplifier configuration. 
• ISE sensors are available with integral conventional analog preamplifier to support cable lengths up to 100 meters (330 feet) as well as Q7M/Q7F NEMA 6P rated snap connector system (see more below). ISE sensors with integral preamplifiers can have their tinned leads bridges across terminal strips in a waterproof J-box enclosure assembly). 
• End of cable terminations are tinned leads standard for both with and without integral preamplifier configurations 
• Quick disconnect IP67 & NEMA 6P rated waterproof and corrosion resistant Q7M/Q7F snap connector option is available for ion selective (ISE) sensors with integral preamplifiers. 

FIELD INSTALLATION CONFIGURATIONS SUPPORTED & ISE SENSOR OPTIONS: 

• Quick-Disconnect Twist Lock Bayonet Style Receptacles allow for easy and fast insertion and removal from process line for calibration and cleaning. Standard in KYNAR® (Poly-Vinylidene-Fluoride, PVDF) material of construction with stainless steel locking pins. 
• The 6XX0 series ion selective sensor can be installed into inline low-flow panel assemblies as well immersed into a tank using a suitable standpipe or guiderod. It is submersible when a waterproofing option is invoked even without the use of an immersion tube to seal the rear threads. 
• Sanitary TRI-CLOVER style installations are supported using the 5XX0 series ion selective sensors employing the same 316SS hardware as for the sanitary pH & ORP sensors. See the pH & ORP sensor configuration page for details about the mating sanitary sensor holder with welded 1.5″, 2.0″ or 2.5″ TRI-CLOVER flange. 
• HOT-TAP valve retractable style installations are also supported using the 5XX0 series ion selective sensors employing the same 316SS retraction hardware assemblies as for the valve retractable pH & ORP sensors. 
• Double O-ring design ensures secure seal during operation with twist lock quick disconnect bayonet (8XX0) type ISE sensors and sanitary/HOT-TAP style ISE sensors (5XX0). o Standard material of construction is Viton®-75, with CV75, Simriz® 485 and Kalrez® 4079 Optional. 
• Back of sensor can be sealed with waterproofing option for use in immersion or submersible type applications as well as for inline use. For immersion and submersible installation it is recommended to add a protective tines option (“GR” or “GRO”) to the 8XX0 twist lock and 5XX0 sanitary/HOT-TAP ISE sensors as well as a suitable waterproofing option. 
• Available options for the ion selective sensors in the 6XX0 series immersion/submersible, 8XX0 inline twist lock quick disconnect & 5XX0 sensors for sanitary / HOT-TAP installations detailed on ISE sensors options section. 
• Extensive ion selective addendum support documentation is provided to ensure best practice field installation of the ion measurement systems using RHINO industrial ion selective sensors (review prior to purchase & commissioning). 

MATERIALS OF CONSTRUCTION & CORE TECHNICAL SPECIFICATIONS: 

• Most ISE sensor with PVC type ion sensing elements (ammonium, calcium, sodium, lithium, …etc) have a temperature range of +5 to +40 ºC (41 to 104 ºF) with a pressure of 1 to 10 psig (6.9 to 69 kPag) o Some PVC type ion sensing elements available in a special style to support use up to +50 ºC (+122 ºF). Inquire to factory if your inline ISE application will be over +40 ºC to see if this condition can be accomodated. 
• Most ISE sensors with solid-state ion sensing element (fluoride, chloride, bromide, iodide, cyanide, ..etc) have a temp range of +5 to +50 degree Celsius (41 to 104 degrees Fahrenheit) with a pressure of 1 to 20 psig (6.9 to 138 kPag) o Special AB 6100 fluoride ISE sensor support up to 70 degrees Celsius (158 degrees Fahrenheit) continuous use
