BL983317 | Hanna Conductivity Controller 0.00-10.00 mS/cm

Take control of your nutrient dosing with the Hanna BL983317, a panel-mounted conductivity controller specifically designed for applications with higher conductivity levels, such as hydroponic nutrient tanks, industrial wastewater treatment, and cooling tower bleed-off in Pakistan.

Unlike the standard drinking water controllers (which measure in microSiemens, µS), the BL983317 measures in milliSiemens (mS/cm) with a range of 0.00 to 10.00 mS/cm. This higher range is essential for agriculture, as nutrient solutions are typically too concentrated for standard meters. The unit features a selectable dosing switch, allowing you to choose between "Low Limit" or "High Limit" dosing logic:

Low Limit Dosing: Activate pump when EC drops below setpoint (e.g., adding fertilizer to a hydroponic tank).

High Limit Dosing: Activate valve when EC rises above setpoint (e.g., bleeding dirty water from a cooling tower).

Technical Specifications:

• Range: 0.00 to 10.00 mS/cm
• Resolution: 0.01 mS/cm
• Dosing Relay: 2A / 250 VAC (Fuse Protected)
• Control Mode: Selectable (Trigger on Low EC or High EC)
• Setpoint: Adjustable from 0.00 to 10.00 mS/cm
• Probe Input: Compatible with HI7632-00 (Sold Separately)

Frequently Asked Questions:

Q: What is the difference between BL983313 and BL983317?

• A: The Range (Concentration).
  • BL983313: Range is 0-1999 µS/cm (approx 0-2 mS). Best for tap water, RO, and drinking water.
  • BL983317 (This Model): Range is 0-10 mS/cm. Best for Fertilizer injection (Hydroponics usually runs 1.5 - 3.0 mS) and Cooling Towers (which run high EC to save water).

Q: Which probe do I need?

• A: This specific model uses the HI7632-00 probe. Note: It uses a different probe than the drinking water models because it needs a different cell constant to measure high EC accurately.

Q: Can I use this to automate fertilizer addition?

• A: Yes! This is the industry standard for that. You set the switch to "Low Limit." When your plants eat the food and the EC drops, the controller turns on your dosing pump to add more fertilizer until the target level is reached.
