BL983319 | Hanna TDS Controller 0-1999 PPM

Automate your nutrient management with the Hanna BL983319, a compact panel-mounted controller designed specifically for Hydroponics and Agriculture in Pakistan. Measuring in the 0 to 1999 ppm range, this unit is engineered for "Low Limit" Control: its relay activates when the TDS level drops below your setpoint.

This logic makes the BL983319 the perfect tool for automatic fertilizer dosing. As plants consume nutrients and the TDS of your reservoir falls, this controller triggers your dosing pump to add more fertilizer until the target concentration is reached. It features a large LCD, a fire-retardant casing, and a multicolor LED that indicates whether it is in measuring, dosing, or alarm mode. The adjustable Overtime Timer (5-30 mins) prevents fertilizer overdose in case of a pump failure or leak.

Frequently Asked Questions:

Q: Can I use this for an RO system alarm?

• A: No. This controller uses "Low Limit" logic (activates when TDS is low). For an RO system, you want an alarm when TDS is high.

If you need a High-Limit alarm for this range (0-999 ppm): You should look at the Hanna BL983329.

Q: Is this the best model for Hydroponics?

• A: Yes. The 0-1999 ppm range covers most leafy greens and vegetables, and the logic is designed to add nutrients automatically.

Q: Does it come with the probe?

• A: No. It requires the HI7634-00 EC/TDS Probe (sold separately), which is easy to install in standard pipe fittings.
