TDS-3: Precision in Water Purity Measurement
The TDS-3 is a pocket-format tester for total dissolved solids and temperature, built for routine spot checks rather than bench work. It reads TDS from 0 to 9999 ppm and temperature from 0 to 80 °C, with a hold function so a reading can be recorded away from the sample point. Facilities teams use it for RO membrane monitoring, incoming mains checks and quick confirmation that a filtration stage is still performing to specification.
COM-80: Multifaceted Water Quality Analysis
The COM-80 combines TDS, electrical conductivity and temperature in one meter, which matters when a single parameter is not enough to characterise a water source. Conductivity reads up to 9999 µS, TDS up to 5000 ppm, and temperature across 0 to 55 °C. It suits cooling-tower monitoring, aquaponics and general process-water QC, where operators need to track EC drift and dissolved-solids load on the same instrument.
COM-100: Advanced Water Quality Expertise
The COM-100 is the higher-resolution option in the combination range, covering TDS, EC and temperature with wider measurement spans and a factory calibration that holds well between services. Where the COM-80 is a monitoring tool, the COM-100 is better suited to work that has to be documented — commissioning reports, water-quality baselines, and troubleshooting a treatment train stage by stage.
pH-200: Accurate pH and Temperature Monitoring
The pH-200 is a waterproof pH and temperature meter reading 0.00 to 14.00 pH and 0.5 to 55 °C, with automatic temperature compensation and a replaceable electrode. pH is usually where dosing problems show up first, so this is the meter we recommend for laboratories, aquaculture operations, pool plant rooms, and any process where a coagulation or neutralisation step depends on holding a narrow pH band.
COM-300: The Ultimate Water Testing Solution
The COM-300 measures pH, TDS, EC and temperature in a single handheld unit — EC from 0 to 9999 µS, TDS from 0 to 5000 ppm, and temperature from 0 to 55 °C. It is the practical choice when one technician covers a full water-quality round and carrying three separate meters is not realistic: one instrument, one calibration schedule, one set of consumables to stock.
