Frequently Asked Questions

Q: What does TDS measure and why does it matter for hydroponics and aquariums?
A: TDS (Total Dissolved Solids) measures the concentration of dissolved minerals, salts, and nutrients in water, expressed in parts per million (ppm). In hydroponics, TDS directly indicates nutrient solution strength — too low means plants are underfed, too high risks nutrient burn. In aquariums and reef tanks, TDS affects water quality and livestock health. The MC410 PRO monitors TDS 24/7 and alerts you the moment levels drift outside your target range.

Q: What is the TDS range and set point range of the MC410 PRO?
A: The MC410 PRO measures TDS from 0 to 1990 ppm with a 10 ppm resolution and ±2% full scale accuracy. The user-selectable alarm set point range is 100 to 1900 ppm, covering the typical TDS requirements for most hydroponic crops, aquariums, and water conditioning systems. A 0.7 conversion factor is used to convert EC to TDS.

Q: Does the MC410 PRO compensate for temperature changes?
A: Yes. The MC410 PRO includes Automatic Temperature Compensation (ATC) from 0 to 50°C, ensuring TDS readings remain accurate as solution temperature fluctuates — critical in grow rooms and greenhouses where temperatures vary throughout the day and night.

Q: How does the MC410 PRO alarm system work?
A: The MC410 PRO features a visual LED alarm that activates automatically whenever TDS rises above or falls below your configured high/low set points. This allows you to monitor nutrient levels passively and only intervene when the alarm triggers — ideal for unattended reservoirs and commercial grow operations.

If you have any questions about shipping costs, please don't hesitate to contact us before placing your order. We apologize for any inconvenience and appreciate your understanding.

Seres reserves the right to notify you of any additional shipping charges. We partner with multiple vendors and locations, which can alter shipping rates.

If you need to change the shipping address, please get in touch with us at support@seresag.com or call 1-877-237-3754.
