อุปกรณ์วัด pH (pH/ORP/ISE/EC/TDS/NaCl Benchtop Meter)

HI 2550 pH/ORP/ISE/EC/TDS/NaCl Benchtop Meter HI 2550 is a 2 channel instrument that measures up to 7 parameters. With this single laboratory bench meter you can measure pH, ORP, ISE, conductivity (EC), TDS, NaCl percentage and temperature. Utilizing an external temperature probe, pH readings are automatically temperature compensated. To ensure a higher level of precision, pH calibrations are up to five calibration points, ...
