Force and mechanical measuring equipment
Designed to be a cost-effective solution for hydroponic gardens or greenhouses to maintain ideal nutrient solution concentration levels in the reservoir. The HI981413 GroLine Nutrient Dosing System is a complete solution with an advanced process controller and a built-in chemical dosing pump. Simply attach the probe and injection valve to the recirculating pump and supply the stock of fertilizer to be dosed.
- Measure EC/TDS/Temperature with only 1 probe
– Display shows EC or TDS and temperature
– Integrated metering pump
– Meter included electrodes and standard solutions, electrode washing.
– Popular and specially designed for glass, greenhouses and measuring in nutrient solutions
There are 3 options:
– HI981413-00: basic
– HI981413-10: with accessories for installation in pipeline
– HI981413-20: includes mounting accessories in measuring cup
The HI981413 Nutrient Dosing System is designed to maintain the concentration of nutrient solutions used in hydroponics and irrigation water. Nutrient concentrations in water used for irrigation are critical to successful plant propagation and growth. The HI981413 uses an amperometric conductivity sensor to measure the amount of fertilizer in the solution. The meter can be programmed to display results as either EC (electrical conductivity) or TDS (total dissolved solids). EC results are displayed as mS/cm while TDS is displayed as ppm with a selectable conversion factor from 0.45 to 0.99. The HI981413 was developed to be an inexpensive solution for gardeners to maintain ideal fertilizer concentrations. Simply insert the probe and injection valve in line with the recirculation pump and deliver the chemical to be dosed.
MULTI-COLOR SCREEN
If in control mode and operating as intended, the display will be green. If the control is not powered on, the display will be yellow while in warning state, the display will flash red.
SMART ALARM SYSTEM
Allows the user to enable or disable low and high level alarms for EC/TDS. When an alarm is triggered, all pumps will stop. For added safety, the alarm system also provides an over-dose protection feature where if the setpoint value is not adjusted within a programmed time period, the display will go into alarm mode.
The HI981413 features a peristaltic metering pump that is superior to diaphragm versions due to its ability to self-adjust when there is no liquid in the suction line.
BRUSHLESS MOTOR
Brushless motors have no gears or brushes that can wear out. The brushless design provides long life and low maintenance. The compact stepper motor allows for very precise control of chemical dosing.
LONG LIFE PERISTILIAL TUBE
Industrial grade peristaltic tubing is chemical resistant and offers a relatively long service life. Since the tubing lasts over time, it can be easily replaced. No special tools required.
HI30003 Amperometric Temperature / Conductivity Probe
The HI30003 probe combines both temperature and conductivity sensors and connects to the controller with a waterproof Quick Connect DIN connector.
NPT thread for in-line mounting and measuring cup
The ABS body of the probe has a 1/2” threaded fitting for mounting to an inline “T” fitting or flow cell. The rear end of the probe has a 3/4” NPT thread for sink/tank mounting. The probe body has a hex socket for tightening with a wrench.
