Models and Accessories:

Models include HM-40X, HM-41X, HM-42X, CM-41X, CM-42X, and MM-43X, each with specific electrodes and solutions.
Common accessories include electrode holders, stands, and attachments, with specific accessories for each model.
Optional accessories include external printers, turntables, stirrers, and data collection software compatible with Windows OS.

Electrodes and Measurement Ranges:

pH/ORP electrodes are available for general use, organic solvents, precise measurements, and high alkaline samples.
Dissolved oxygen electrodes are available for immersion and no-flow measurements, with various membrane sets.
Conductivity cells are available for general, low, and high electrical conductivity uses, with immersion and flow-through types.
Ion electrodes cover a wide range of ions, including fluoride, chloride, cyanide, sodium, potassium, calcium, nitrate, ammonia, carbon dioxide, bromide, iodide, cadmium, copper, silver, and sulfide.

Calibration and Solutions:

Standard solutions and ionic strength adjusters are provided for calibration and measurement accuracy.
Specific solutions are available for different ions, ensuring precise measurements.

Recommendations and Notes:

Ensure compatibility of electrodes and solutions with specific measurement requirements.
Consider interference from coexisting ions and conduct pretreatment if necessary to prevent measurement errors.
Contact the manufacturer for guidance on ion measurements, especially when dealing with coexisting samples.

Specifications and Functionality:

pH Meters: Models HM-42X, HM-41X, and HM-40X use glass electrode methods for pH measurement, platinum electrode methods for ORP, and thermistor resistors for temperature. They feature touch panel color graphic LCDs or customized LCDs. Measurement ranges for pH are 0.000 to 14.000, with ORP ranging from -2000.0 to 2000.0 mV. Temperature ranges from 0.0 to 100.0°C.
Conductivity Meters: Models CM-42X and CM-41X use AC 2-electrode methods for conductivity and thermistor resistors for temperature. They offer auto-selection of measuring frequency (80Hz/3kHz) and display ranges depending on the cell used.
Multi-Function Water Quality Meter: Model MM-43X supports multiple measurement methods including pH, ORP, ion, conductivity, and dissolved oxygen. It features a touch panel color graphic LCD and allows for simultaneous or single display of two channels.

Calibration and Performance:

pH calibration supports JIS, US, and customized standard solutions with a maximum of 5-point calibration. Ion and temperature calibrations are also supported.
Conductivity meters offer auto and manual range switching, with temperature compensation ranges from 0 to 100.0°C.
Performance is guaranteed within a temperature range of 0 to 45°C and humidity below 85% without condensation.

Additional Features:

Data memory capacity varies by model, with some supporting up to 2000 data entries.
Optional external printer connectivity is available for certain models.
Security functions, auto hold, and statistical calculation functions are included in select models.

Power and Dimensions:

Power sources include AC adapters and AA alkaline batteries, with power consumption ranging from approximately 3 VA to 18 VA depending on the model.
Dimensions for main units are approximately 130W x 60H x 230D mm, with weights ranging from 0.7 kg to 0.9 kg.

Standard Accessories:

Standard accessories include pH electrodes, standard solutions, KCL solution, electrode holders, and attachments.

Electrode Ion replacement chip Measurement range(Optimal pH range) Intereference of coexisting ion*1/ Note * 1 Interference of coexisting ion If an ion coexists in the solution, it can cause data errors when measuring the targeted ion. A selectivity coefficient of 10x means that if the solution contains a coexistent ion that is 10x times greater than the value of the targeted ion that is measured, an error occurs in which the value of the targeted ion equals the coexistant ion value. If the concentration level of the coexistent ion is high enough to affect the measured values, we recommend...
