Dissolved oxygen, salinity, turbidity, chlorine and multiparameter meters for water analysis in labs, aquaculture and treatment plants.
TL;DR
We supply water testing instruments in Thailand, including Hanna HI97701 and HI97711 chlorine photometers and DO, turbidity and multiparameter meters. Reagent refills and replacement cuvettes can be ordered alone with the meter model and item code. Every item is quoted on request.

Water analysis selection guide
01
Write free chlorine or total chlorine, not just chlorine. Include the expected minimum and maximum, reporting unit and decision limit from your method or customer requirement. For example, a value reported as a substance is not automatically interchangeable with a value reported as its constituent element.
02
Hanna HI97701 measures free chlorine over 0.00 to 5.00 mg/L as Cl₂. For a requirement covering both free and total chlorine, the manufacturer offers HI97711 with separate reagent choices. This illustrates why a quotation must name each result and reagent code, even when instrument ranges look alike.
03
The HI98494 listed in our catalog uses pH/ORP, conductivity and optical DO sensors. Its multiparameter label does not mean it performs the chlorine photometer methods above. Match every requested parameter to a documented channel, sensor or photometric method.
04
State monthly sample tests plus blanks, quality-control checks and repeats required by the method. For photometers, list reagent codes, pack sizes, cuvettes and storage limits. For sensor systems, include the relevant caps, maintenance solutions and replacement sensors. Compare total recurring requirements rather than assuming one cost always dominates.
05
Request model-specific check standards where appropriate. Hanna HI97701-11, for example, has a certificate carrying its lot, reference values and expiry. Keep a manufacturer quality certificate, a standard certificate and a separately requested calibration service as distinct quotation items. Specify site, cable length and record-export needs.
Yes. Send the meter model, full item code and pack quantity so we can check compatibility and supply. State whether you need cuvettes alone or caps too: Hanna lists HI731331 as a pack of four glass cuvettes without caps. The reagent code and method must also match your existing instrument.
Start with a parameter matrix. A multiparameter sensor instrument and a multiparameter photometer support different techniques. Mark which device, sensor or method produces each required result before deciding whether one instrument is enough.
Only use the reagent and procedure specified for the result. Hanna lists HI93701-01 for free chlorine and HI93711-01 for total chlorine in its HI97711 reference guide. Similar packaging or a common instrument does not make the methods interchangeable.
No. A model-specific check standard verifies the instrument against a reference; the sample test still uses its stated reagent and procedure. Check which standards are included in the exact kit and which need separate ordering.
Compare the same workload and verification plan: tests per month, reagents per test, control and repeat use, expiry losses and replaceable sensor parts. Ask for an itemized supply list so a lower instrument price does not conceal an incomplete setup.
Request the pack quantity and confirm whether caps are also needed.
Send the existing meter and method when requesting total-hardness reagents.
Free-chlorine photometer; confirm reagents and check standards.
Free and total chlorine with the appropriate method-specific reagents.
A separate pH, conductivity and optical DO sensor system.
Pair pH and conductivity measurements with colorimetric testing.
These references support the named chlorine-method comparison, check-standard documents, sensor-system example and replacement-cuvette pack. Verify the current model, method and kit supplied in Thailand before ordering.
Specifications, compatibility and supplied documents vary by model and option. Check them against your method and the current manufacturer data sheet before ordering. Supplying equipment does not validate a method or certify compliance.
