Training HI5522 ISE fluoride HI4010 and HI4107 Chlorida in balikpapan East Kalimantan factory nickel

The HI4010 is a solid state, half-cell ion selective electrode (ISE) for the determination of fluoride (F-) in solution. Calibration HI4010 using Hanna standard HI4010-30 1 ppm standard with tissab and HI4010-10 10 ppm standard with tissab  The HI4107 is a solid state, combination ion selective electrode (ISE) for the determination of chloride (Cl-) in solution. calibration HI4107 using standard user for ISE Chlorida 20,50,100,500,1000 ppm (custom calibration) after calibration the result same with standard buffer , thank you for choose Hanna instrument.
