Original product description
The EC-I503 is a laboratory ion meter designed to measure ion concentration in solution. It supports pX, mV, ion-concentration, and temperature measurement modes through a 5.0-inch color touch-screen interface. Documented measurement ranges include -2.000 to 20.000 pX, -2000.00 to 2000.00 mV, and -30.0 to 135.0°C.
Concentration values can be expressed in mg/L, g/L, mol/L, mmol/L, or pX. The instrument provides direct measurement, including continuous measurement, as well as sample-addition, standard-addition, and Gran-addition methods.
Calibration can use one to five points, with a configurable reminder interval of 1 to 999 hours. Selectable endpoint modes are Auto, Manual, and Time. Temperature operation supports ATC and MTC. Listed built-in ion types include H+, Na+, K+, Ag+, NH4+, F-, Cl-, I-, NO3-, CN-, Ca2+, Cu2+, Pb2+, and S2-.
Self-defined ion types are also supported. Because measurement suitability depends on the electrode and method, buyers should confirm the required ion-selective electrode, standards, concentration range, sample matrix, and temperature-compensation approach for their procedure.
The EC-I503 stores up to 2,000 measurements and retains the most recent calibration data for up to 10 electrodes. Electrode input is BNC with specified impedance above 3 × 10^12 Ω. The temperature input is Cinch for an NTC 30K Ω sensor. RS232 and USB outputs are listed, while printer support is optional.
Reported accuracy specifications are ±0.002 for pX and ±0.005 for pX II;±0.1 mV or ±0.005% of full scale for mV;±0.3% for concentration C and ±0.5% for concentration C II;and ±0.1°C for temperature.
Buyers should confirm how these accuracy classes apply to the intended ion, electrode, calibration standards, measurement range, and operating conditions.
Before procurement, verify the complete supplied configuration, included electrode and temperature probe, required accessories, data-export workflow, optional printer compatibility, plug type, and electrical input. The documented supply options are 110–220 V AC at 50/60 Hz and 9–12 V DC.
Also confirm whether the stated 250 × 165 × 65 mm housing dimensions exclude the electrode holder and accessories.
