Hach IntelliCal™ Smart Probes
HQ4300 model accepts up to 3 probes at once
Hach IntelliCal™ Smart Probes
Choose from a huge variety of parameters and styles
Hach IntelliCal smart probes store their own testing parameters, calibration history and settings. HQ meters recognize each probe so you can move probes between meters without recalibrating, minimizing errors and setup time. Proven technology delivers superior accuracy and response times&mdasdh;even with challenging samples or difficult operating environments.
Choose from rugged or standard probes. Rugged probes feature an IP68 stainless steel body and polymer sensor shroud with a steelsheathed cable; they are waterproof to 30 meters. Standard pH probes feature built-in ATC.
ORP probes have an epoxy body. Conductivity probes use a 4-pole graphite design. LDO and LBOD probes are immune to hydrogen sulfide and heavy metals interference and have no membranes to clean or replace—just replace the sensor cap about once a year.
Ammonia, ammonium, chloride, fluoride, nitrate and sodium IntelliCal ISE electrodes are also available.
Meter Only includes: Li-Ion batteries, USB wall charger, USB A to micro B cable (5.9-ft), wrist strap and manuals. Meter Kits include: IntelliCal conductivity probe, carrying case, three 90-mL containers and 1413 uS/cm Singlet® standard (pack of 20). 3-year meter warranty.
