Its compact format is suitable for users who need conductivity and dissolved-solids readings without carrying a full-size portable meter.\u003c\/p\u003e\n\u003cp\u003eThe tester measures conductivity from 0 to 3999 µS\/cm, TDS from 0 to 2000 ppm and temperature from 0.0 to 60.0°C. Automatic temperature compensation corrects EC and TDS readings as sample temperature changes, while the user-selectable TDS factor and temperature coefficient help adapt the instrument to different water types. Automatic one-point calibration supports 1413 µS\/cm, 1382 ppm or 1500 ppm standards. A dual-level LCD displays the water-quality value together with temperature, and the stability indicator helps users identify when the result is ready to record.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMeasurement Tip: \u003c\/strong\u003eRinse the probe with clean water and then with a small amount of the next sample to minimise cross-contamination. Wait until the stability symbol disappears before recording the result. The user-replaceable AD32P probe reduces long-term ownership cost. Buy ADWA AD31 from Kamadi Pakistan for convenient EC and TDS testing.\u003c\/p\u003e\n\u003ch2\u003ePocket EC\/TDS Tester Selection Guide\u003c\/h2\u003e\n\u003cp\u003eChoose the AD31 when you need a waterproof pocket tester for conductivity levels up to 3999 µS\/cm and TDS values up to 2000 ppm. It is a practical choice for routine low-to-medium conductivity water testing. The package includes the replaceable AD32P probe, protective cap, 1413 µS\/cm calibration solution sachet, four 1.5V batteries and a user manual.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eMeasures conductivity, TDS and temperature\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eWaterproof housing sealed against humidity\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAutomatic temperature compensation for EC and TDS\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAutomatic one-point calibration with stability indication\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eUser-replaceable AD32P EC and temperature probe\u003cbr\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eModel: AD31\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eProduct Type: Waterproof EC, TDS and Temperature Pocket Tester\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eConductivity Range: 0–3999 µS\/cm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTDS Range: 0–2000 ppm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTemperature Range: 0.0–60.0°C \/ 32.0–140.0°F\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eResolution: 1 µS\/cm \/ 1 ppm \/ 0.1°C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAccuracy: ±2% full scale for EC\/TDS; ±0.5°C for temperature\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCalibration: Automatic, one point\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eTDS Factor \/ Temperature Coefficient: 0.45–1.00 \/ 0.0–2.4% per °C\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eProbe \/ Power: Replaceable AD32P probe \/ four 1.5V batteries\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eApplications\u003cbr\u003e\n\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDrinking-water quality checks\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eReverse-osmosis and filtration monitoring\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eHydroponic nutrient-solution testing\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eAquariums and aquaculture systems\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eLaboratory and field water analysis\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ADWA Instruments","offers":[{"title":"Default Title","offer_id":45973564948737,"sku":"142310001","price":26800.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0731\/5659\/1873\/files\/adwa_ad31_pocket_ec_tds_meter.jpg?v=1785181682","url":"https:\/\/kamadi.pk\/products\/adwa-ad31-conductivity-tds-temperature-tester","provider":"Kamadi Pakistan","version":"1.0","type":"link"}
