hydroCHEM-DS Conductivity
and pH
Dosing System
|
|
Full Size Image |
 | Fully
configured controller for Conductivity and pH in Hydroponic applications.
|
| Temperature readout is
provided, and optional temperature control output is optionally available.
All components are pre-installed onto the single panel. All that the
end-user needs to do is cut the tubing
to the desired lengths plug it in and turn it on. Low maintenance,
reliable peristaltic pumps. Supplied with all fittings and accessories.
|
| The new advanced design
makes this unit far superior and yet cheaper and easier to use than other
brands. The hydroCHEM Dosing System is the culmination of over 30 years
manufacturing experience.
|
| The hydroCHEM Dosing
System is quite simply the best hydroponics controller available anywhere
in the world in its price bracket. |
|
| Pre-installed onto mounting panels. No further installation
required. |
| Waterproof construction rated to IP65. |
| Highly reliable peristaltic pumps included. |
| Memory for 2300 stored readings, with automatic datalogging facility
(optional). |
| RS232 Interface for remote monitoring of system (optional). |
| Flow sensing to ensure system functions correctly. |
| Large digit mode makes the data easy to read in any light or from a
distance. |
| Automatic calibration |
| 4 Terminal conductivity sensor technology resists fouling for
maximum reliability. |
| User can choose readout in mS/cm, CF units, dS/M or ppM (TDS). |
|
| Quick-dose function |
| Temperature readout with optional temperature control output. |
| Fully adjustable ON and OFF times can be set separately for
Conductivity and pH pumps, eliminating over-dosing. |
| User can select acid or alkali addition. |
| Password protection, so only qualified users can change set-up or
calibration. |
| Good laboratory practices (GLP) function brings analytical Q.A. to
the hydroponics farmer. Instant recall of current calibration and
system set-up information. |
| 24 Hour calendar clock (optional). |
| Emergency shutoff timer shuts off Conductivity and pH pumps if they
operate continuously for user-set time. |
| Operates off a single AC/DC power supply. No electrical installation
required. |
