HANNA Graphic LCD Portable Meters with pH, ORP and ISE(2 pt cal), meter only.
|Quantity in Basket:
|METER ONLY****Graphic LCD Portable Meters with pH, ORP and ISE
ISE Calibration Up to 5 point calibration with 6 standard solutions.
Good Laboratory Practice Calibration data, date and ID information are stored for retrieval at a later time.
Six models are available to cover all applications. All meters feature HANNAs exclusive Calibration Check: the pH electrode state is compared to the previous calibration and the user is warned in the event of significant changes to avoid erroneous calibration due to a bad/dirty electrode or a contaminated buffer. The electrode condition is always displayed on the LCD and the OUT OF CALIBRATION RANGE warning alerts the user if the measurement is taken too far from the calibration points.In addition to all the features of the pH models, these meters also include direct ion concentration determination with ISEs. HI 98185 allows a choice of measurement units (ppm, ppt, g/L, mg/L, ppb, µg/L, mg/mL, M, mol/L, mmol/L, % w/v, user) and ISE electrode type selection (ammonia, bromide, cadmium, calcium, carbon dioxide, chloride, cupric, fluoride, iodide, lead, nitrate, potassium, silver, sulfate and sulfide). HI 98184 measures in ppm and the ion charge or nominal electrode slope can be entered manually. Up to 5 calibration points with six standard values are available.
HI 98184 are supplied with HI 72911B combined pH/Temperature electrode, pH 4.01 and pH 7.01 buffer solutions; (4) 1.2V AA, 1300 mAh rechargeable batteries; HI 710042-01 inductive battery charger with power adapter; rugged carrying case and instructions.
