It uses Apera's proprietary 2301T-S Brush-Resistant Platinum Black (BPB) conductivity electrode, which features an integrated temperature sensor for automatic temperature compensation. The meter measures EC, TDS, and temperature simultaneously on a large backlit LCD, with stability indicators and calibration-status icons to help operators confirm that readings have settled and calibration has completed successfully.\u003c\/p\u003e\n\n\n\u003cp\u003eWith an EC measurement range of 0–200 mS\/cm, the EC400 can test low-conductivity reverse-osmosis (RO) water, standard nutrient feeds, runoff, and concentrated stock solutions. Its IP57-rated housing is designed for dusty, humid, and splash-prone production environments. The complete kit includes three premixed calibration solutions and a rugged hard-shell carrying case, making it suitable for daily checks across multiple mixing stations and reservoirs.\u003c\/p\u003e\n\n\n\u003cp\u003e• Product Type: Portable handheld conductivity and TDS meter kit\u003cbr\u003e\n• Brand: Apera Instruments\u003cbr\u003e\n• Model: EC400\u003cbr\u003e\n• SKU: AI412\u003cbr\u003e\n• Measurement Parameters: Electrical conductivity (EC), total dissolved solids (TDS), and temperature\u003cbr\u003e\n• EC Measurement Range: 0–200 mS\/cm\u003cbr\u003e\n• TDS Range: 0–100 g\/L\u003cbr\u003e\n• EC Resolution: 0.01 \/ 0.1 \/ 1 µS\/cm and 0.01 \/ 0.1 mS\/cm, depending on range\u003cbr\u003e\n• EC Accuracy: ±1.0% of full scale ±1 digit\u003cbr\u003e\n• Temperature Measurement Range: 0–80°C (32–176°F)\u003cbr\u003e\n• Temperature Compensation Range: 0–50°C (32–122°F), automatic or manual\u003cbr\u003e\n• Temperature Accuracy: ±0.5°C ±1 digit\u003cbr\u003e\n• Included Electrode: Apera 2301T-S BPB conductivity\/temperature electrode\u003cbr\u003e\n• Electrode Technology: Brush-Resistant Platinum Black (BPB) coating designed to improve measurement stability and resist fouling from nutrient particulates\u003cbr\u003e\n• Electrode Cable Length: 3 ft\u003cbr\u003e\n• Display: Large backlit LCD showing EC, TDS, and temperature simultaneously, with measurement-stability and calibration-status indicators\u003cbr\u003e\n• Calibration: Automatic 1–3-point calibration with smart self-diagnosis\u003cbr\u003e\n• Calibration Solutions: Three premixed reference solutions included\u003cbr\u003e\n• Configurable Settings: Solution standards, TDS conversion factor, temperature coefficient, temperature unit (°C\/°F), backlight duration, and automatic power-off time\u003cbr\u003e\n• Water and Dust Protection: IP57-rated housing, designed for dust-tight protection and temporary immersion\u003cbr\u003e\n• Power Supply: Four AA 1.5V batteries\u003cbr\u003e\n• Primary Applications: Nutrient-solution testing, source-water verification, reservoir monitoring, and runoff EC checks\u003cbr\u003e\n• Suitable Growing Systems: Hydroponics, coco coir, rockwool, and other commercial fertigation systems\u003cbr\u003e\n• Included Accessories: EC400 meter, 2301T-S BPB conductivity electrode with 3 ft cable, three premixed calibration solutions, and rugged hard-shell carrying case\u003cbr\u003e\n• Recommended Use: Routine verification of incoming water, prepared nutrient feeds, and runoff at mixing stations and reservoir banks\u003c\/p\u003e\n\n\n\u003cp\u003eKey Advantage: The Apera EC400 combines a wide 0–200 mS\/cm conductivity range with simultaneous EC, TDS, and temperature display in a rugged, portable instrument.
