Dosatron Etatron eOne Micro-Doser Kit – 3/4 Inch (Lo-Flo)

The Dosatron Etatron eOne Micro-Doser Kit – 3/4 Inch (Lo-Flo) is an ultrasonic injection system for accurately dosing super-concentrated fertilizers and chemicals into an irrigation line. With a built-in flow sensor and pressure relief valve, it delivers reliable proportional injection for smaller-scale fertigation lines using 3/4" NPT connections. It can integrate with a Dosatron Water-Powered Nutrient Delivery System or operate independently as a stand-alone solution.

Why Choose the Etatron eOne Micro-Doser Kit

The Etatron eOne MF kit is built around ultrasonic dosing technology, which enables precise injection of super-concentrated products at low volumes — a capability that standard peristaltic or venturi-type injectors often cannot match at the small volumes required for high-concentration formulas. Here is what differentiates this kit from a generic injector:

• Ultrasonic micro-dosing precision: The MF (Micro-Flow) ultrasonic pump is specifically designed to handle super-concentrated products accurately, reducing waste and dosing error compared to volumetric peristaltic pumps at comparable flow rates.
• Integrated flow sensor: The included flow sensor monitors water movement through the line in real time. This allows the doser to meter injection proportionally to actual flow rather than relying solely on a timer or manual calibration.
• Pressure relief valve included: The kit includes a pressure relief valve to protect the dosing unit and the irrigation line from pressure spikes, reducing the risk of component failure in pressurized systems.
• Flexible deployment: The kit is designed to work either in combination with a Dosatron Water-Powered Nutrient Delivery System — adding electronic precision to water-powered injection — or as a fully independent stand-alone injector where no Dosatron unit is present.
• Lo-Flo sizing for smaller lines: The 3/4" NPT, Lo-Flo configuration is matched to lower-volume irrigation lines. Growers running smaller greenhouse or propagation zones can size the injector correctly to their actual line flow rather than over-specifying with a large-bore unit.

Best Uses for the Etatron eOne Micro-Doser Kit

This kit is suited to applications where accurate, low-volume injection of concentrated products into a pressurized water line is a priority. The 3/4" NPT Lo-Flo configuration points to smaller irrigation circuits rather than large main-line installations.

• Commercial greenhouse fertigation: Integrating into existing drip or overhead irrigation lines to deliver fertilizer at consistent, measured rates across each irrigation event.
• Propagation and nursery zones: Smaller-diameter 3/4" lines typical of propagation benches or rooting zones benefit from the Lo-Flo sizing, where precise micro-dosing of rooting aids or starter nutrients is important.
• Supplementing a Dosatron system: Adding the eOne to an existing Dosatron Water-Powered Nutrient Delivery System extends the system’s capability by enabling injection of super-concentrated additives that are impractical to run through a standard water-powered proportioner.
• Stand-alone injection where water pressure is available: Where no water-powered Dosatron unit is installed, the eOne can serve as the primary injector for a fertigation zone, provided a stable water supply with adequate pressure is present.
• pH or adjuvant dosing: In systems that require precise chemical injection beyond standard nutrients — such as pH-down acids or biological products — ultrasonic micro-dosing reduces the risk of over-injection compared to manual addition or coarser dosing equipment.

Compatibility & System Integration

The Etatron eOne Micro-Doser Kit uses 3/4" NPT threaded connections and is configured for Lo-Flo lines. Before purchasing, confirm your irrigation line diameter and flow rate fall within the Lo-Flo operating range for this model. The 1 1/2" Hi-Flo variant is available separately for higher-volume main lines.

The kit is designed to integrate into an existing fertigation system and is explicitly compatible with Dosatron Water-Powered Nutrient Delivery Systems. In combination, the Dosatron unit handles bulk nutrient proportioning while the eOne handles precise micro-dosing of concentrated additives — a split that is common in larger commercial grows where multiple products are injected at different rates. For growers monitoring water quality alongside nutrient delivery, pairing this system with a dedicated inline EC or pH sensor is standard practice; see the Apera GroStar GS3-E replacement EC electrode for a compatible sensor option used in hydroponic water management setups.

The kit’s pressure relief valve provides a degree of protection against pressure excursions, but the system should be installed on a line that operates within the doser’s rated pressure range. If your water supply requires pre-treatment before entering the irrigation system, a compact reverse osmosis unit upstream of the injector can reduce dissolved solids in the source water and improve dosing accuracy.
